Omron E5ZN Series Manual

E5ZN Operation
Nomenclature
E5ZN (Orders for the E5ZN series will not be accepted after March 31, 2019.)
• The E5ZN is a Temperature Controller that features the ability to be built into equipment.
• The E5ZN is equipped with RS-485 communications, so process values can be monitored and parameters can be read or written from the host
system.
• The Terminal Unit can be separated from the Controller, so maintenance can be performed on the Controller without changing the wiring.
• If two or more Controllers are connected to the same host system, use an expansion Terminal Unit and close mounting to safe space and
reduce wiring.

Setting 0
Unit number 00
Set a different unit number for each E5ZN if more than one is connected using RS-485 communications.
Communications cannot be performed if the same unit number is used more than once on the same line.
Baud Rate
Set the baud rate of the Controller to match the baud rate of the host system.
Setting 0
Baud rate (bps) 4800
