Power Supply
1) Supply the power to PLC (master unit).
Communication Establishment Check
• Confirm that the communication has been established with the
LED lamp on EC Gateway Unit.
* Refer to "Troubleshooting" in this first step guide
Slave Devices
• Confirm that communication is established also on PLC (master unit).
* Refer to PLC Instruction Manual.
Check on Safety Circuit
