Hello all,
I need to talk to a GE 90-30 series PLC using the RS232 protocol. I need to be able to send data strings in the following format to the PLC via RS232 from a PC:
stx <Data> etx
Is this easy enough to do?
I'm OK with the PC side of things but I'm unsure of how this will be achieved in the PLC. For example, is this possible through the RS232 port of the PLC? and if so how do I “see” or access the data in the PLC?
What I need to do ultimately is fire different PLC outputs depending on the data value received. Again I'm OK with this, it's getting and comparing the data in the PLC that's the problem.
Any help would be greatly appreciated.
Thanks, AJ
