Omron FINS Ethernet Driver Displays "Device '<device name>' responded with write not possible (Tag '<tag name>', Size '<size>').[Main, Sub: '0x21, 0x08']" Error Message

Last Update: 11/7/2018
Possible Cause:
This error may indicate that the controller's rotary switches are set incorrectly.

Verify that the rotary switch labeled "UNIT No." is set for the Unit Number. Then, verify that the two rotary switches labeled "NODE No." are set for Node No (which is typically the same as the right-most octet of the device's IP address).

For more information, refer to Main and Sub Error Codes in the Omron FINS Ethernet help file.
