2. Core functions

It is a hosted hub designed to be used in conjunction with GE Fanuc’s VMIxxx-5565 series reflective memory real-time network products for embedded systems

When signal loss or loss of effective synchronization mode is detected, the port can be automatically bypassed to keep other nodes in the network running

The optical port adopts a small form factor pluggable (SFP) transceiver, which only needs to be configured with the required port. It can be combined with multi-mode (short distance) or single-mode (long distance) transceivers to save small network costs and optimize the system

For large networks, multiple VMIAC-5595 components can be cascaded, supporting up to 256 nodes

The reflective memory network can be monitored and controlled through a simple PC serial port (RS232 port) or through a local area network (LAN) or web browser (Ethernet port)

3. Control and Status

Additional control registers allow manual disabling of transmitters on any port

The front panel manual switch includes a received momentary reset switch and a Gang Select switch. The Gang Select switch configures the VMIACC-5595 port as an 8-port loop or two independent 4-port loops

The three LEDs next to each port provide visual indications of port status, and additional status indications and operating modes can be obtained through serial or Ethernet ports

The status information includes detection of installed transceivers, detection of signals (light), detection of effective synchronization modes, and port operation speed (2Gb/s)

Control registers allow channel bypassing based on the absence of a single valid synchronization mode or multiple synchronization modes, as well as signal (light) loss. Each port can be manually activated or bypassed, regardless of the status indicator

4. Ethernet controller

10BaseT interface conforms to Transmission Control Protocol/Internet Protocol (TCP/IP) standard

Each hub component has a unique MAC address and can run on a local area network (LAN) or a wide area network (WAN)

Contains a remote user interface available via standard Ethernet connection, controlled by a standard HTML based web browser, displaying status data, supporting bypass mode, “dark to dark”, and forcing each port on/off or automatic, all of which are saved in NVRAM

Functional characteristics

1. Basic Introduction

VME-3125A provides isolated 12 bit analog-to-digital conversion with 32 single ended analog voltage input channels (16 differential) for VMEbus’s 6U Eurocard. The optional gain and A/D range support an input voltage range of ± 50mV to ± 10V, and the current input option supports 32 single ended channels with ranges of 0 to 20mA, 4 to 20mA, and 5 to 25mA. To minimize system software overhead, all inputs are continuously scanned and digitized at a total sampling rate of 40000 samples per second, and the measurement data of each channel is accessed by VMEbus at any time through a dual port data register. For voltage input, a 40Hz low-pass input filter can be selected to minimize the impact of system noise, and the standard unit is equipped with a 50kHz low-pass filter.

2. Core functions

Programmable Gain Amplifier (PGA): Jumper options include series voltage gain x1, x10, or x100 for all channels; For voltage input, the full range of the A/D converter can be selected as ± 5V, ± 10V, or 0 to+10V; the data encoding software can be selected as offset binary or binary complement code

Input configuration: The input can be configured with 16 differential voltage channels or 32 single ended voltage or current channels through jumper wires; A single front panel 37 pin ultra small D-type connector provides connections for all input channels

Working mode: All 16 or 32 input channels are continuously scanned at the maximum sampling rate, and the resulting data is stored in a dual port data register for VMEbus to access; After any reset operation, the scan automatically starts without the need for additional programming to initiate the A/D conversion process

Built in Test Function (BIT): By selecting the BIT working mode, the operation of PGA, ADC, and related control logic can be verified. In this mode, the internal reference voltage is applied to the input of PGA, bypassing the analog input multiplexer. All data channels read through the control interface will reflect the selected BIT reference voltage

3. Features related to VMEbus

Compliance: Compliant with VMEbus standard ANSI/IEEE STD 1014-1987, IEC 821 and 297, with 6U external dimensions

Board address: The physical address is selected through the onboard address jumper, using VMEbus address lines A07 to A15; The VME-3125A board occupies 128 bytes of address space and can be located on any 64 word boundary of the short I/O (A16) space

Address Modifier: Address modifier bits are selected and decoded through jumpers to respond to non privileged short I/O access, monitoring short I/O access, or both access privileges

4. System reset and indicator lights

System reset: System reset establishes the following board states: all channels automatically scan, front panel diagnostic LED indicator lights up, offset binary data format

Front panel system diagnostic LED: The software controlled front panel LED lights up when the system is reset and can be turned off under software control to provide an external indication that the built-in test has been completed

Simulate input data format

The analog input is digitized and stored in 32 dual port data registers (16 registers for differential operation) as a 12 bit right aligned digital value. The software can select data codes as offset binary and binary complement. In binary complement encoding, the sign bit (D11) is extended to the most significant bit (D12 to D15) of the data register.

Introduction

Product Features

128 bit TTL input/output

16 8-bit I/O port jumpers, allowing for selection of input or output operations on 8-bit boundaries

24mA current injection capability

Supports 8-bit or 16 bit data transmission

Function description: High density TTL I/O board, supports up to 128 bit TTL input or output through user installed port direction control jumpers. Each jumper sets an 8-bit port as an input or output port, and each output has a current absorption capacity of up to 24mA. It is designed with a high-quality ground plane to enhance noise resistance. When the system is reset, all I/O ports are initialized to inactive state, and all ports are activated by writing to I/O register 7

Reference materials: including “The VMEbus Specification” and various application and configuration guides provided by VMIC, such as “Digital Input Board Application Guide”

Working principle

Block diagram: The functional block diagram is divided into six sub parts: VMEbus basic logic, data transceiver, address comparison logic, read/write register control logic, registers 0-3, and registers 4-7. There are also multiple subsystem block diagrams

Board addressing: supports data transmission of monitoring or non privileged short I/O memory space, selects I/O access type through jumper, factory configured to respond to short monitoring I/O access, and has two board selection DIP switches for setting the board’s base address

VMEbus basic logic: including typical VMEbus drivers, receivers, and control logic

Register read/write control logic: Address bits A01, A02, A03 and read/write control lines are decoded into eight write control lines and eight read control lines, routed to the enable pins of each bidirectional latch, which can be selected for read or write operations through jumper wires

Data transmission description: The corresponding I/O data register is selected for data transmission through address bits A3, A2, and A1 combined with a data gating signal. The board selection signal generates an active signal for data transmission with DSO and DS1 logic gates. The board selection also activates a delay signal to generate a delayed version, which is used to provide setup time for the data transceiver during the write cycle before locking the data into the I/O register. The DTACK signal indicates that the data has been latched (write cycle) or is valid (read cycle)

I/O port enable description: The system reset signal (powered on or initiated by the VMEbus master device) disables all I/O ports/registers, and enables all I/O ports by writing to the I/O register R7L, regardless of whether they are configured as input or output ports

Programming

I/O register mapping: 12 bit addresses (A15 to A04) are used for board selection decoding, and the address switch is set to match these bits to generate data transfer board selection signals. The 128 bit I/O is divided into eight 16 bit registers for word transfer, and address bits A03, A02, and A01 are used to decode one of the eight registers, with a detailed I/O register mapping table

I/O port direction: Programming should be consistent with the I/O configuration selected by the jumper in the I/O port direction. The output port can only write data, and the input port can only read data. Please refer to Section 5 for jumper configuration details

Configuration and installation

Unpacking procedure: Product components may be sensitive to electrostatic discharge, unused boards should be stored in their original packaging, and it is recommended to use conductive materials when placing them. After receiving them, check for any transportation damage and handle them promptly

Physical installation: Power off installation or removal of the board, insert the board into the appropriate slot of the chassis, ensure correct alignment and orientation

Jumper and switch positions: Refer to Figure 5.3-1 for information on jumper and switch positions

I/O port direction jumper configuration: Table 5.4-1 specifies the use of jumpers J10 to J25, and installing jumpers will configure the corresponding ports as input ports

Address modifier: Factory configured to respond to short monitoring I/O access, installing jumper J9 can be changed to respond to short non privileged I/O access

Address selection switch: There are two address selection switches on the board, and Figure 5.6-1 shows their use in the addressing scheme

I/O cable and card edge connector configuration: The I/O connectors (P3 to P6) are 64 pin DIN standard, designed with high-quality ground planes connected to VMEbus ground and alternating I/O pins for connectors. They support connection to connectors P3, P4, P5, and P6 through four cables and have connector pin/channel allocation tables

Maintenance

Maintenance points: When the product malfunctions, it is necessary to check the software, system configuration, electrical connections, jumper or configuration options, whether the board is fully inserted, whether the connector pins are clean, whether adjacent board components are interfered with, cable and I/O connection quality, etc. If it needs to be returned for repair, it is necessary to contact VMIC to obtain a Return Merchandise Authorization (RMA) number

Ordering information

The meaning of each parameter in the ordering options: A represents the type of relay (0 is a latch relay, 1 is a non latch relay); B is the number of channels (0 is 64 channels, 1 is 32 channels); C is a reserved option (0).

Functional feature details

Recommended P3 and P4 cable connection connector components: The matching connector for 96 pin IDC is ERNI No.913.031, and the 0.033-inch ribbon cable (96 pin large-scale termination) is ERNI No.913.049; The matching connector for the 96 pin discrete wire is Harting No.09 03 096 3214, the female pressure contact point is Harting No.09 02 000 8484, and the connector housing is Harting No.09 03 096 0501; The printed circuit board connector is ERNI No.913.216. The Harting crimping tool model is 09 99 000 0075.

Basic function: Provides 64 C-type latch relay contacts through two 96 pin DIN connectors, with an additional set of normally closed contacts for built-in testing (BIT). The latch relay remains in state after power failure until a change command is received.

Contact configuration: C-type contacts include normally open (N.O.), normally closed (N.C.), and common contacts. Normally open and common contacts can form A-type contacts, while normally closed and common contacts can form B-type contacts. The normally open contacts are located in row A of the connector, and the common contacts are located in row C. This arrangement allows 64 core cables to be used for A-type switches.

Relay and BIT logic: Bipolar relays are used on the board, with only one pole leading out to the user and the other pole used by BIT logic. When reading the board, the status of the control data register or normally closed pole will be read. The control register and relay address are the same, and users can monitor the status of both user contacts and control registers simultaneously. Due to the fact that the reading pole and the user pole are controlled by the same coil, BIT can monitor the user contacts through the normally closed contacts of the second pole.

Control and feedback: When writing logic 1 to the data register, the normally closed contact provides logic 1, achieving positive data feedback for the BIT logic of the contact. Writing logic 1 to the control register activates the relay, causing the normally open contact to close and the normally closed contact to open. When reading the BIT logic of the contact, it returns logic 1. Due to the long time required for the relay state to change (up to 7ms), users can avoid misjudgment by checking the data register status instead of waiting for the relay contacts to close.

Compliance: Complies with ANSI/IEEE STD 1014-1987, IEC 821, and 297 VMEbus specifications, with parameters A24, A16: 3D/39, 2D/29: D32, D16, D08 (EO): slave equipment.

Addressing scheme: The base address of the board contains the board ID, with a 16 bit CSR above it. The output register is located on the next long word boundary above the CSR, and the contact register is located above the output register. The output and contact registers can be addressed as 16 8-bit bytes, 8 16 bit words, or 4 32-bit long words, located on any 128 bit boundary within the standard data or short monitoring/non privileged I/O space.

Board addressing: 20 jumpers are used to select the base address of the board, 1 jumper determines the address space (standard data or short I/O), 1 jumper selects monitoring, non privileged, or any access mode, and the remaining 18 jumpers set the base address of the board.

Non latch option: If the non latch option is ordered, a standard relay will be used, and the contact data will not be affected. However, when the power is cut off, the contacts will not remain in the state. Reset and power-off will cause the relay to return to the normal position (normally open contacts open, normally closed contacts closed), and other operations are the same as the latch version.

Functional feature details

Basic functions: It can detect COS with 64 digital inputs, perform time tagging and counting. The onboard buffer can store COS information with time tags to analyze SOEs. The pulse accumulator is used to count COS. When COS is detected, it can be programmed to issue an interrupt, and each channel processes it independently.

COS timing: The input signal is latched every millisecond, and after a programmable debounce time (1.25ms-1.024s), if a valid COS is detected, it will be time marked and stored by a millisecond timer. The minimum reliable detection pulse time is 2ms.

COS detection: Programmable detection of rising edge, falling edge, or both, detecting COS can generate interrupts or disable.

Time stamping: Each COS event can be marked with a timer value of 0-65s, which updates every millisecond. When the maximum value is reached, it resets to zero and notifies the host.

Sequence of Events (SOE): SOE memory is allocated to two buffers (each capable of storing 3000 events), where the host processes one buffer while the other can load new event data. SOE logic can issue interrupts to the host at the end of the buffer or when the user sets a count.

Pulse Accumulation: Each channel has a Pulse Accumulation Count (PAC) register, and when the count reaches 65535, it will notify the user through a flag in the control register or issue an interrupt.
