Omron TXDU Instruction

7 posts in this topic

Does anybody have the details on the TXDU command for the new version 3 serial cards for the CS1/CJ1? Omron has not updated their manuals yet. I need to setup the RS-232 port on a CJ1W-SCU41 to no-protocol. The instruction help in CXP version 5.0 does not show the breakdown of the control words. Thanks in advance for any help.

You are correct,lIllE. TXD/RXD is for use with CPU mounted serial ports including V1.2 SCBs and above. TXDU/RXDU is for Serial Communication Units.
