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
