Parameters
6.5 Setting to prevent continuous RUN in TEST MODE
(1) What the setting to prevent continuous RUN in TEST MODE is
The setting to prevent continuous RUN in TEST MODE is for preventing a continuous
RUN for a long time in TEST MODE.
If the RUN state in TEST MODE exceeds the restriction time (continuous RUN
tolerance time in TEST MODE), the "TEST MODE TIME EXCEEDED" (error code:
8100) continuation error occurs.
(2) Measuring the continuous RUN operation time in TEST MODE
(a) Measurement start
When the CPU module goes into RUN status in TEST MODE, the measurement
of the RUN continuous time in TEST MODE starts.
(b) Measurement stop
When the CPU module goes into the state below, the measurement of the
continuous RUN operation time in TEST MODE is stopped and the measurement
value is cleared.
• When the CPU module is put into the STOP status
• When the PLC is power-off
• When the CPU module is reset
Remark
1. The continuous RUN operation time in TEST MODE is not measured during
operation in SAFETY MODE.
2. Measurement of the continuous RUN time in TEST MODE continues even if
the operating time in TEST MODE exceeds the set continuous RUN tolerance
time and the "TEST MODE TIME EXCEEDED" (error code: 8100)
continuation error occurs.
