    1.0 INTRODUCTION The products described in this instruction manual are manufactured by RelianceR Electric Industrial Company. The AutoMax R Net Processor module (M/N 57C429) provides the means for an AutoMax/DCS 5000 rack to communicate over the R Net industrial network. The R Net network allows AutoMateR Processors, AutoMax/DCS 5000 Processors, and/or other devices (mini computers, color graphics terminals, etc.) to communicate with each other to create a distributed control or centralized...

  • Page 9: Mechanical/Electrical Description

    2.0 MECHANICAL/ELECTRICAL DESCRIPTION This section describes the mechanical and electrical characteristics of the AutoMax R Net Processor module. Mechanical Description The AutoMax R Net Processor module is a printed circuit assembly that plugs into the backplane of the AutoMax/DCS 5000 rack. The module consists of the printed circuit board, faceplate, and protective enclosure.

    The resulting number indicates one of the following fault conditions: EPROM checksum error Scratchpad RAM failure Dual port memory failure Node number switch setting greater than 250 Communication circuit failure Local watchdog interrupt Software test (negative buffer length detected) Software test (message length = 0 detected) Unused interrupt detected Attempt was made to access a word on an odd byte (address error)

  • Page 11: Electrical Description

    Electrical Description Network operation is controlled by a Motorola 68010 CPU/direct memory access (DMA)/serial I/O architecture. 16K bytes of dual port memory is provided to store the network variables. All program application data is sent and received by the AutoMax R Net Processor module's CPU.

    3.0 INSTALLATION This section describes how to install and replace the AutoMax R Net Processor module. For more information regarding the R Net network, refer to the R Net Application Manual (J 3075). DANGER ONLY QUALIFIED ELECTRICAL PERSONNEL FAMILIAR WITH CONSTRUCTION AND OPERATION OF THIS EQUIPMENT AND THE HAZARDS INVOLVED SHOULD INSTALL, ADJUST, OPERATE, AND/OR SERVICE THIS EQUIPMENT.

  • Page 14: Wiring

    Wiring The installation of wiring should conform to all applicable codes. To reduce the possibility of noise interfering with the control system, exercise care when installing wiring from the system to external devices. For detailed recommendations, refer to IEEE Standard 518 (Guide for the Installation of Electrical Equipment to Minimize Electrical Noise Inputs to Controllers).

  • Page 15: Module Replacement

    Step 8. Turn on power to the rack. An internal diagnostic routine is automatically executed by the module. If an error is encountered, the pattern of red LEDs will indicate the fault code. If all diagnostics are passed, the red LEDs will turn off.

    4.1.1.3 Register 13 (Slot Number) Register 13 indicates the slot location of the AutoMax R Net Processor module. 4.1.1.4 Register 14 (Messages Received Count) Register 14 indicates the number of messages received by the AutoMax R Net Processor module since power up. This register will increment (up to 32767) as messages are received.

  • Page 20: 12Register 22 (Response Time In Seconds)

    this register should be set to the highest number node that is on the system plus 1. Nodes on the network should be numbered consecutively to avoid unnecessary delays in transmission on the network. The maximum node number value should be identical in all devices connected to the R Net network.

  • Page 21: Globals

    AutoMax/DCS 5000 variables are mapped to the AutoMate image area during configuration and can be accessed by any task in any AutoMax/DCS 5000 Processor in the rack. (Refer to section 4.3 for more information regarding configuration). When AutoMax/DCS 5000 variables are referenced in application tasks, the data is directly obtained from/written to the AutoMate image.

  • Page 23: Figure 4.5 Use Of Global Coils

    When enabled by the Transmit Global Data Enabling Registers (registers 50 53), the individual points within these registers are broadcast to all other drops on the network. A global coil is enabled by setting its corresponding bit in the Transmit Global Data Enabling Registers.

  • Page 24: Command Buffer Area

    4.1.3 Command Buffer Area The command buffers in the dual port memory are used to store the commands for the AutoMax R Net Processor module that are generated by the GATEWAY_CMD_OK@ function. The buffers are controlled by the GATEWAY_CMD_OK@ function and are not used by the user.

  • Page 25: Read Register

    4.2.3 Read Register The Read Register command (003) is used to read data in up to 120 sequential registers. When initiated by the GATEWAY_CMD_OK@ function, this command will transfer 16 bit data from AutoMate registers to the AutoMax R Net Processor module's AutoMate image registers.

  • Page 26: Configuration

    Configuration Before running any application tasks, the system must be configured. The major function of configuration is to assign meaningful symbolic names to physical points in the system. This feature allows you to construct application tasks using variable names instead of actual physical locations.

  • Page 27: Figure 4.6 Gateway_Cmd_Ok@ Returned Status Error Codes

    returned status will contain an error code. Refer to figure 4.6 for error codes returned by the GATEWAY_CMD_OK@ function. Error Code Description 00 = Error Free 01 = Invalid Command Number 02 = Invalid Parameter/Incorrect Parameter Number 03 = Address Out of Range 04 = Count Error 05 =...
  • Page 28 Sample Application Program The following application program example illustrates the use of the GATEWAY_CMD_OK@ function to initiate a Read Point command. As described in section 4.4, R Net network variables on the R Net Processor module must be defined before they can be accessed by an application task.
  • Page 29 5.0 DIAGNOSTICS AND TROUBLESHOOTING This section describes how to troubleshoot the AutoMax R Net Processor module. If the problem cannot be corrected using the procedures below, the unit is not user serviceable. DANGER ONLY QUALIFIED ELECTRICAL PERSONNEL FAMILIAR WITH CONSTRUCTION AND OPERATION OF THIS EQUIPMENT AND THE HAZARDS INVOLVED SHOULD INSTALL, ADJUST, OPERATE, AND/OR SERVICE THIS EQUIPMENT.
  • Page 30 Communication Line Failure Problem: The top and/or bottom red LEDs on the module faceplate flash on and off. This indicates a CRC error or lost token timeout, respectively, signaling a communication line failure. The RECV LED may also be off indicating a communication line failure. The cause of a communication failure is a lack of integrity along the high speed line.
