Hi,
I am working on the OMRON CPM2A PLC Communication with a PC using RS-232C No-protocol communication.
The purpose of this small project is that as soon as I send a character in the Hyper Terminal using the pre-defined protocol in the PLC PC Communication setup by setting DM 6645 to DM 6649 areas I expect the PLC turns the Reception Completed Flag (AR 0806) ON and stores the received character data into DM 0200 area and also want to see the output LED 1005 is turned ON on the PLC front pannel.
Here is an Example that I used in the test.
DM 6645 1001 <- RS 232C mode and No-protocol communication
DM 6646 0030 <- 9600, E,7,1
DM 6647 0000 <- Transmission delay
DM 6648 1000 <- Start Code is Disabled and Endcode found in DM 6649
DM 6649 0D00 <- CR End Code
Another question is about the sending the data in the Hyper Terminal.
Is there anything to keep in mind about the COM port settings?
Then thank you.
