● Fall-back Operation of Analog/Digital Output Modules
As described in Section 8.1.2, “Checking Operation Specification of Analog/Digital
Output” of Chapter 8, “Detailed Description,” an analog/digital output module
performs fallback if it detects a loss of line access with the CPU module beyond 4
seconds.
Cause output fallback using the following procedure and check the control operation
after output fallback is activated.
1. Stop control operation on the FCN-500 or FCN-RTU using Logic Designer’s
Project Control dialog.
2. Press the shutdown button of the FCN-500 or FCN-RTU or execute Shutdown
from the Maintenance homepage of the FCN-500 or FCN-RTU to put the FCN-
500 or FCN-RTU in “Power Off OK” state.
