9.2 Error Details
(1) Types of errors
The following errors are detected by the QD60P8-G.
(a) Overflow
error
This error occurs if the accumulating count value overflows (exceeds
99999999) when the count type of the accumulating counter is the linear
counter.
To clear this error, turn ON the error reset request (Y8 to YF). Further, to
start count operation properly, set "1" in the "counter reset request" of the
buffer memory.
(b) Buffer memory setting range outside error
This error occurs if any setting error is found by a check made on the
values set to the buffer memory when the operating condition setting
request flag (Y1) turns ON. It occurs if any setting value in the "comparison
output setting value" or similar of the buffer memory is outside the range.
To clear this error, set a correct value and turn ON the operating condition
setting request flag (Y1) again.
(c) Intelligent function module switch setting error
This error occurs if any setting error is found by a check made on the
setting values of the switch settings for intelligent function module set in the
PLC parameter when power is switched from OFF to ON or the
programmable controller CPU is reset.
To clear this error, set a correct value on GX Developer, perform write to
PLC, and then switch power from OFF to ON or reset the programmable
controller CPU.
(d) Module
error
This error occurs if a fault occurs in the module for some reason.
Change the module if the error occurs again after power is switched from
OFF to ON or the programmable controller CPU is reset.
