9.245 Fanuc-PLC9030

This page describes the device driver and the device window for the Fanuc-PLC9030 device. This device controls up to 320 inputs and up to 320 outputs at a Fanuc Series 90 / 30 PLC. It communicates to the PLC through a CCM (Communication Coprocessor Module) and requires the PLC to be configured in a special way (see the paragraph at the end of this chapter).

The Fanuc-PLC9030 device driver is part of the sat-nms framework for M&C of plain digital I/O functions. Monitoring alarm circuits or controlling waveguide switches are indicatives for applications of this framework.

The application configuration normally does not access the Fanuc-PLC9030 device driver directly. There are a couple of application level logical devices (e.g. Input , Output or WG-Switch ) which may use the Fanuc-PLC9030 device driver as a low level driver to access the physical I/O ports.

Port addressing

The device driver gives access to the I/O ports through five integer variables each for inputs and for outputs. Each variable stands for 64 input or output ports, which in total results in a pool of 320 input and 320 output ports.

The variables are named in way, that a translation of a particular port to a bit position in the variable is quite easy. Example:

An input port which appears in the Fanuc PLC as '%I00066' is accessed through the variable I00065 of the device driver. It is represented by the bit 2^1 in the variable (the least significant bit represents the '%I00065' input).

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

• --- Shows / commands I/O port states.
• --- The faults page.
• --- The device info page.
• --- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the Fanuc PLC.

Configuring the Fanuc PLC for the usage with this driver

To use a Fanuc 90/30 PLC as an I/O module for the sat-nms software, the PLC must be equipped with a CCM (Communication Coprocessor Module). The sat-nms software does not support a communication through the CPU serial interface.

The PLC must be configured in the following way (using a hand held controller ot the Fanuc PC software):

• Each I/O module must be placed in the input resp. output table at the lowest possible address. There must not be gaps of unused port addresses in the input/output tables.
• The total number of configures I/O ports must be set at the configuration page of the Fanuc-PLC9030 device in the sat-nms software (configuration parameters 'inputPorts' and 'outputPorts'.
• If the PLC is running a program, that actively sets or clears any output ports, the sat-nms software will not recognize these changes. The software always will signal the setting which recently was commanded. The state of outputs in the PLC is read back only after power on / after communication loss.
• The CCM must be configured to the following settings:
  • Configuration mode --- CCM ONLY
  • CCM Enable --- YES
  • CCM Mode --- SLAVE
  • Interface --- RS232
  • Data Rate --- 19200
  • Flow Control --- NONE
  • Parity --- ODD
  • Retry Count --- NORMAL
  • Timeout --- LONG
  • Modem ... --- NONE
  • CCM CPI ID --- 1

The required settings are the factory settings of the CCM as described in the Fanuc "Series 90 PLC Serial Communications User's Manual".
