(3) Output status for each status
Depending on the states of the data link and head module, data may not be able to be output.
The following table shows how the states of the data link and head module affect the output (Y).
-: Not dependent on the status
Switch Head module status Data link status Output (Y) status
RUN Operating normally
Cyclic
transmission in
progress
Varies depending on the status and settings of the Motion controller. (  User's manual for the
Motion controller used)
(1)
If the Motion controller is in the stop error status:
The output (Y) status follows the "Error Time Output Mode" setting in the PLC Parameter.

The analog output status of the digital-analog converter module and analog input/output
module follows the setting of the analog output HOLD/CLEAR function.

(2) When the Motion controller is in the STOP status:
The output (Y) turns off.
The analog output status of the digital-analog converter module and analog input/output
module follows the setting of the analog output HOLD/CLEAR function.

The refresh device status of the Motion controller is as follows:
• Turns off if "Y" is specified for the CPU side device.
• Holds its status if "other than Y (M, L, etc.)" is specified for the CPU side device.

RUN Operating normally Disconnected
The output (Y) status is held for 3.5ms after the communication with the Motion controller is
terminated due to a break in the SSCNET III cable or other possible causes.
The output (Y) status after disconnection follows the "Error Time Output Mode" setting in the PLC
Parameter. (
