Unit Configuration Example
Minimal Configuration
Small Systems with 2 Channels or 4 Channels Communicating with the Host Device via RS-485
(CompoWay/F Protocol)
• Alarms can be allocated to the auxiliary output for the End Unit.
• G3ZA/G3PW outputs can be used.
Multiple Units without an EJ1N-HFU
Building Systems Communicating with the Host Device, such as a PLC, PT, or Computer, via RS-485
(CompoWay/F Protocol)
• The 2 auxiliary alarm outputs provided on the End Unit can be used for integrated alarm systems.
• G3ZA/G3PW outputs can be used.
• Distributed placement is possible by using multiple EJ1C-EDU End Units.
Multiple Units with an EJ1N-HFU
Using the EJ1N-HFU@-NFL@ to Build a System Communicating 1:1 with a PLC Using Programless
Communications
• The 2 auxiliary outputs provided on the End Unit can be used.
• The 4 event inputs and 4 auxiliary outputs of the HFU can also be used.
• G3ZA/G3PW outputs can be used.
• Distributed placement is possible by using multiple EJ1C-EDU End Units
