(7) Analog output HOLD/CLEAR function
The following describes Trigger output request (RY19, RY29) and the analog output HOLD/CLEAR function.
• Even if Trigger output request (RY19, RY29) is turned on while the analog output HOLD/CLEAR function is
being executed, the D/A conversion is not performed. This is the same for the trigger output request
assigned to the extension digital input module as an external signal.
• Even when the operating status of the CPU module is back to RUN, the analog output value is not updated
until the D/A conversion is performed by another Trigger output request (RY19, RY29).
