I thought the issue was not having a serial port on your computer.......If you get a USB to serial convertor, you will need to use COM1 thru COM4 at 9600,E,7,2.

You need a USB to Serial convertor. Omron makes one - CS1W-CIF31. Many other manufacturers make one.

The connector on the CPM1 is not RS232C level signals. Instead, it is TTL level signals. You need a CPM1-CIF01 adapter and then the serial cables in the post above will work.

Two ways to send more profiles to the C200H-NC111:
1. Send new data to the Data Memories like you are currently doing. You must send a restart to the module to get the new data to be read by the module. This involves either 1.) power off and back on again or 2) setting bit...
Use the keyence Instruction DIFU - Differention Up (commonly known as rising edge one-shot.)

Try out the ZEN nano controller. It ha a built in display for setting up the unit. Less Expensive than S3D8

Unfortunately, this is a common thread that runs through all Japanese PLCs. Mitsubishi, Omron, Idec, Aromat, etc. all offer only one timer - the on delay timer. All other forms of timing have to be built with logic using the on-delay timer. Jay in Dallas

The method that you describe was exactly the way manufacturers did multidrop before tristate RS422/485 was invented. The firmware of the node, though, was responsible for the re-transmission of the signal.
As long as your remote nodes are "listen" only, you should be able to get by...
The Omron CPM2A or CPM2C can provide both the quadrature input and the pulse output to control either stepper or pulse-driven servo.
