Am I trying to do something that is already done for me?
We are setting up communications between a SLC 5/04 and an Opto 22 Brain using serial communications.
The basic premis is the transmission of an ASCII string to and from the PLC which shares the data needed.
My concern comes in the error proofing of this string between the 2 controllers. Do I need to create a check sum routine inside the Ladder logic to validate the string?
Does the CRC option for the channel 1 port allready do this for me?
Does anyone have any ideas or insight into this issue?
Thanks in advance,
Tim
