PLC Systems with CPU Firmware Versions Prior to 5.03

In order to support TCP/IP configuration mode, you must have Logicmaster 90-70 release 6 and PLC CPU firmware version 5.03 or later. Certain CPU models (CPU 780, 788, and 789) cannot support firmware version 5.03 or later. To allow support of TCP/IP Client features (COMMREQs) in pre-5.03 CPUs that cannot support TCP/IP configuration mode. We support reduced functionality Client support through MMS-Ethernet configuration mode.

To compensate for the lack of TCP/IP configuration mode, the pre-5.03 CPU user must take two additional steps that the users of TCP/IP configuration mode do not:

(1)configure TCP/IP parameters (including the IP address of the Ethernet Interface) in the GSM, and (2) use the Assign Channel Status Vector COMMREQ to specify the location of the sixty-four (64) Channel Status bits.

1.Move the cursor to the desired rack and slot location. The slot may be either unconfigured or previously configured.

2.Press the Communications softkey, i.e., Comm (F6). Your screen display will change to the one shown on the following page.
