A01 MULTI CPU ERROR 4352
Details
- An incorrect number of devices were designated with the exclusive instruction for multi-CPUs high-
speed communication set in the program.
Remedy
- Read the common information of the error using a programming tool, check error step corresponding
to its numerical value (program error location), and correct the problem.
A01 MULTI CPU ERROR 4353
Details
- An unusable device was designated with the exclusive instruction for multi-CPUs high-speed
communication set in the program.
Remedy
- Read the common information of the error using a programming tool, check error step corresponding
to its numerical value (program error location), and correct the problem.
A01 MULTI CPU ERROR 4354
Details
- An unusable character string was designated with the exclusive instruction for multi-CPUs high-
speed communication set in the program.
Remedy
- Read the common information of the error using a programming tool, check error step corresponding
to its numerical value (program error location), and correct the problem.
A01 MULTI CPU ERROR 4355
Details
- An invalid number of read/write data (number of request/response data) was designated with the
exclusive instruction for multi-CPUs high-speed communication set in the program.
Remedy
- Read the common information of the error using a programming tool, check error step corresponding
to its numerical value (program error location), and correct the problem.
A01 MULTI CPU ERROR 5000
Details
- The scan time of the initial execution type program exceeded the initial execution watch time
specified in the PLC RAS setting of the PLC parameter dialog box.
Remedy
- Read the individual information of the error with a programming tool, check its value (time), and
shorten the scan time.
A01 MULTI CPU ERROR 5001
Details
- The program scan time exceeded the WDT value specified in the PLC RAS setting of the PLC
parameter dialog box.
Remedy
- Read the individual information of the error with a programming tool, check its value (time), and
shorten the scan time.
- Resolve the endless loop caused by jump transition.
A01 MULTI CPU ERROR 5010
Details
- The program scan time exceeded the constant scan time specified in the PLC RAS setting of the
PLC parameter dialog box.
- The low speed program execution time specified in the PLC RAS setting of the PLC parameter
dialog box exceeded the excess time of the constant scan.
Remedy
- Review the constant scan setting time.
- Review the constant scan time and low speed program execution time in the PLC parameter so that
the margin time of constant scan may be fully reserved.
