14 Multi CPU Errors (A) [C80]
A01

Multiple CPU synchronization processing error

Details
The program run section of a synchronous interrupt program has been exceeded.
The multiple CPU synchronous interrupt program (I45) has not been completed within the program run
section.
Remedy
Check the detailed information (time information) in the module diagnostics to verify its value (time), and
take the following actions:
(1) Review the processing details on the multiple CPU synchronous interrupt program so that its processing
is to be completed within the period specified in the fixed scan interval setting.
(2) Set the period specified in the fixed scan interval setting to an appropriate value.
A01

Receive queue full

Details
Number of reception requests of transient transmission exceeded upper limit of simultaneously process-
able requests.
Remedy
Lower the transient transmission usage frequency, and then perform again.
A01

Receive processing error

Details
Transient reception failed.
Remedy
Lower the transient transmission usage frequency, and then perform again.
A01

Transient data error

Details
Too many processings of transient transmission and cannot perform transient transmission.
Remedy
Correct the transient transmission execution count.
A01 Constant scan time error
Details
The scan time exceeded the constant scan time set in the CPU parameters.
Remedy
Check and correct the constant scan time setting.
A01 Module configuration error
Details
The module type set in the system parameters ("I/O Assignment Setting") differs from that of the module
actually mounted.
Remedy
Re-set the module type in the system parameters in accordance with the CPU module or intelligent func-
tion module actually mounted.
A01 Module configuration error
Details
The I/O numbers set in the system parameters ("I/O Assignment Setting") are overlapping between mod-
ules.
Remedy
Re-set the I/O numbers in the system parameters in accordance with the intelligent function module or I/
O module actually mounted.
