Please check if the communication address is good.

Check communication address setting of software and the device.

1. Check if communication ID set in the device is same with communication ID set in a soft
ware.
See [Setting Changes] > [SETUP MENU F1] > [Communication Address (Board ID or Co
mmunication ID)] and check a communication address set in the device.
2. When you use several devices together, communication addresses set in the devices sh
ould be different from each other.
3. Check if baud rate is same with baud rate set in a software.
See [Setting Changes] > [SETUP MENU F1] > [Baud Rate] and check baud rate set in the
device.
* If you initialize the device, baud rate is set to 9,600 bps which is the default.
1.3

Please check if the communication port setting is good.

Check if communication port set in software is same with communication port set in PC.
1.4

Please check if the termination resistor is connected.

For long distance communication of RS422 or RS485, a resistor is connected to match impe
dance to reduce distortion and attenuation which are caused by delay. This resistor is called
termination register.
In the case that several controllers are installed, the termination resistor should be
connected to the last controller and the last controller only.
The device dose not communicate with PC. p.77
