Error
Code Error Contents and Cause
(SD0)
• The scan time of the initial execution
type program exceeded the initial
5000 execution monitoring time specified in
the PLC RAS setting of the PLC
parameter.
• The scan time of the program
exceeded the WDT value specified in
5001
the PLC RAS setting of the PLC
parameter.
The program scan time exceeded the
constant scan setting time specified in
the PLC RAS setting of the PLC
parameter.
5010
The low speed program execution time
specified in the PLC RAS setting of the
PLC parameter exceeded the excess
time of the constant scan.
The scan time of the low speed
execution type program exceeded the
5011 low speed execution watch time
specified in the PLC RAS setting of the
PLC parameter dialog box.
Corrective Action
• Read the individual information of the
error from the peripheral device,
check its value (time), and shorten
the scan time.
• Change the initial execution
monitoring time or the WDT value in
the PLC RAS setting of the PLC
parameter.
• Resolve the endless loop caused by
jump transition.
• Read the individual information of the
error using the peripheral device,
check its value (time), and shorten
the scan time.
• Change the initial execution
monitoring time or the WDT value in
the PLC RAS setting of the PLC
parameter.
• Resolve the endless loop caused by
jump transition.
• Review the constant scan setting
time.
• Review the constant scan setting time
and low speed program execution
time in the PLC parameter so that the
excess time of constant scan can be
fully secured.
Read the individual information of the
error using the peripheral device, check
the numerical value (time) there, and
shorten scan time if necessary. Change
the low speed execution watch time in
the PLC RAS setting of the PLC
parameter dialog box.
