2 Operation CX-Programmer Port Settings Use CX-Programmer to change and download the following Serial Port communication settings for the PLC port that the CP1-MODTCP61 is mounted in. • 115200 Baud Rate • 8,1,N Format • Serial Gateway Mode • 20 Response Timeout (20*100 ms = 2.0 seconds) *1 Note 1 Setting the Response Timeout value for 2.0 seconds will optimize communications recov- ery when a timeout occurs. Peripheral Service To maximize the throughput of the CP1W-MODTCP61, the amount of time per PLC scan that is allowed for servicing communications ports should be increased.
This setting applies for both Slave/Server and Master/Client modes and is accessed through the PLC Settings in CX-Program- mer. On the Peripheral Service tab, uncheck the ‘default’ option, and enter 50 (5.0 ms). Transfer these settings to the PLC and cycle power to apply the changes.
