Tcp/Ip Send Failed; Unsend Data Send Error; Module Moderate Error; Parameter - Mitsubishi Electric M800 Series Manual

M800/M80/E80/C80 Series Alarm/Parameter Manual
14 Multi CPU Errors (A) [C80]
A01

TCP/IP send failed

Details
Data was not sent correctly with TCP/IP.
Remedy
Check the settings for connection with the external device.
Check the operation of the external device or switching hub.
Since there may be congestion of packets on the line, send data after a certain period of time.
Check if the connection cable is disconnected.
Check that there is no connection failure with the switching hub.
Execute the PING test, and if the test was completed with an error, take the corrective action.
A01

Unsend data send error

Details
Unsent data found, but could not be sent.
Remedy
Check the settings for connection with the external device.
Check the operation of the external device or switching hub.
Since there may be congestion of packets on the line, send data after a certain period of time.
Check if the connection cable is disconnected.
Check that there is no connection failure with the switching hub.
Execute the PING test, and if the test was completed with an error, take the corrective action.
A01

Module moderate error

Details
A moderate error has been notified from the intelligent function module connected.
Remedy
Check the detailed information (system configuration information) of the error by executing module diag-
nostics using the engineering tool, identify the error module, and eliminate the error cause.
A01 Module moderate error
Details
An inter-module synchronous signal error has been notified from the intelligent function module connect-
ed.
Remedy
Check the detailed information (system configuration information) of the error by executing module diag-
nostics using the engineering tool, identify the error module, and eliminate the error cause.
A01 Another CPU module moderate error
Details
A moderate error has been notified from another CPU module.
Remedy
Check the detailed information (system configuration information) of the error by executing module diag-
nostics using the engineering tool, identify the error module, and eliminate the error cause.
Check the mounting status and reset status of other CPU modules.
A01 Multiple CPU synchronization processing error
Details
The execution interval of a synchronous interrupt program has exceeded the set value.
The run of a multiple CPU synchronous interrupt program (I45) has not finished within the multiple CPU
fixed scan communication period.
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.
