Output read-back function
Reads back output results and diagnoses whether the external output signals (Y0 to Y7) are correctly output.
By diagnosing whether the output terminal status matches the output data of the safety device, the output read-back function
detects output operation errors of the safety remote I/O module.
To use this function, setting parameters is not required.
Operation at error detection
When the safety remote I/O module detects an error with the output read-back function, the output read-back error (error
code: 0106H) state is applied and all output points are turned off. For details on the error state, refer to the following.
Page 118 Error codes related to the safety remote I/O module
The maximum output voltage in the output OFF state is 1.2V. However, even if the voltage exceeds 1.2V due
to a short circuit or failure of the hardware, no error is detected until the voltage exceeds 7V. Thus, connected
devices may turn on even when the output of the safety remote I/O module is in the OFF state.
