[WDT ERROR]
The execution time of one high-speed interrupt
exceeded 100ms.
■Collateral information
• Common information: Time (value set)
• Individual information: Time (value actually
measured)
■Diagnostic timing
• Always
• If the processing time of the high-speed
interrupt program is long, review the
program.
• Cancel sampling trace, data logging, scan
time measurement, and step specification
for executional conditional device test in
the interrupt program.
RUN: Off
ERR.:Flashing
CPU Status:Stop

[PRG. TIME OVER]
The program scan time exceeded the constant
scan time specified in the PLC RAS tab of "PLC
Parameter".
■Collateral information
• Common information: Time (value set)
• Individual information: Time (value actually
measured)
■Diagnostic timing
• Always
Review the constant scan setting time.
RUN: On
ERR.:On

[PRG. TIME OVER]
The low speed program execution time set in the
PLC RAS tab of "PLC parameter" exceeded the
excess time of the constant scan.
■Collateral information
• Common information: Time (value set)
• Individual information: Time (value actually
measured)
■Diagnostic timing
• Always
• Review the constant scan setting time.
• To secure sufficient excess time, correct
the value for "Constant scanning" and "Low
Speed Program Execution Time" in "PLC
Parameter".

[PRG. TIME OVER]
The program scan time exceeded the constant
scan setting time specified in the PLC RAS tab of
"PLC parameter".
■Collateral information
• Common information: Time (value set)
• Individual information: Time (value actually
measured)
■Diagnostic timing
• Always
Review the constant scan setting time in
"PLC parameter" so that the excess time of
constant scan can be fully secured.

5011
[PRG. TIME OVER]
The scan time of the low speed execution type
program exceeded the low speed execution watch
time specified in the PLC RAS tab of "PLC
parameter".
■Collateral information
• Common information: Time (value set)
• Individual information: Time (value actually
measured)
■Diagnostic timing
• Always
Read the individual information of the error
using the programming tool to identify the
numeric value (time). Check the value and
shorten the scan time.
Change the low speed execution watch time
in the PLC RAS setting of "PLC Parameter".
