Connecting a PC to a PLC

The devices used to test this Driver are the following:

BASE 10-SLOT (IC693CHS391D)

SERIES 90-30 POWER SUPPLY (IC693PWR321R)

CPU 351 (IC693CPU351-DF)

ETHERNET CONTROLLER (IC693CMM321-BA)

INPUT SIMULATOR MODULE (IC693ACC300D)

OUTPUT 12/24 0.5A 32PT POS (IC693MDL753D)

STAT. MGR to PC (IC693CBL316A) cable

TRANSCEIVER

 

The steps for assembling these devices are described next.

1.Plug the POWER SUPPLY, CPU 351, ETHERNET CONTROLLER, INPUT, and OUTPUT into the rack (BASE 10-SLOT) as explained on document Series 90-30 Programmable Controller Installation Manual.

2.Connect one side of the STAT cable on CPU port 1 and the other side on the computer's serial port. This step is only necessary if the PLC's IP address is not configured yet.

3.Connect one end of the TRANSCEIVER to the corporate Ethernet and the other end to the ETHERNET CONTROLLER (side connection).

4.Plug the POWER SUPPLY feed cable to an outlet. Its PWR frontal led must be turned on.

5.Use LM90 software to program the PLC and to modify its IP address according to the network used. For more information about the IP address to use, please check the Appendix D - Assigning IP Addresses of Host Communications Toolkit for C/C++ Application User's Manual (GFK - 0870B). If LM90 returns a time-out error, there are errors in device's installation. Please check the serial port used by LM90 to communicate.
