How Communication Works
ZS Series controllers have communication functions with external devices. Use this function to
read the data in ZS Series controllers from the host and to write the setting data.
Communication is achieved via the Command and Response Method based on the
CompoWay/F, which is Omron's proprietary communication protocol. Controllers perform
processing according to the command sent from the host, and then return the result to the host
which sent the command as a response.
