Error Status (S1+34, S1+35)
Indicates the PIDD error status.
Error Code
The analog input specified for Analog
101
Input is not configured.
PV Upper Range Value or PV Lower
Range Value is out of the range when
the PIDD instruction is started.
102
PV Upper Range Value or PV Lower
Range Value is set to an out-of-range
value while the PIDD instruction is being
executed.
An out-of-range value is set to MV High
103
Limit or MV Low Limit.
An out-of-range value is set to SP High
106
Limit or SP Low Limit.
Process Variable (PV) is set to a value
109 outside the range of PV Lower Range
Value to PV Upper Range Value.
The analog I/O module settings that were
111
set for Analog Output are incorrect.
Kp (Gain) is set to a value outside the
122
range of 0.00001 to 100.0.
Manual Mode Output MV is set to a value
130
outside the range of 0.0 to 100.0.
Control Period is set to a value outside
132
the range of 0.1 to 50.0.

Countermeasure
Check the analog I/O module settings.
Check if PV Upper Range Value or PV
Lower Range Value is set to an out-of-
range value, and check if PV Lower
Range Value ≥ PV Upper Range Value.
Check if MV High Limit or MV Low Limit is
set to an out-of-range value, and check if
MV Low Limit ≥ MV High Limit.
Check if SP High Limit or SP Low Limit is
set to an out-of-range value, and check if
SP Low Limit ≥ SP High Limit.
Check if the process variable is outside
the range of PV Lower Range Value to
PV Upper Range Value.
Check the analog I/O module settings.
Check the Kp (Gain) setting.
Check the value of Manual Mode Output
MV.
Check the control period settings.
