5-6 Optional Communications

Standard Omron Protocol

The communications function allows you to monitor and set E5CK parameters by a
program prepared and running on a host computer connected to the E5CK controller.
When using the communications function, you must add on the unit for RS-232C or RS-
485 communications. The E5CK communications function allows you to read/write
parameters, do operating instructions, and select the setting level.
