Description and steps to take
E40 I/O error Selectable With FP3/FP10SH, communication error in the MEWNET-TR
system has occurred.
For all other PLCs an abnormality in an I/O unit has been
detected.
Check the contents of special data registers DT9002 and
DT9003/DT90002 and DT90003 and the erroneous
MEWNET-TR master unit or abnormal I/O unit (also expansion
unit or application cassette). Then check the unit.
Selection of operation status using system register 21:
 to continue operation, set K1 (CONT)
 to stop operation, set K0 (STOP)
E41 Intelligent unit error Selectable An abnormality in an intelligent unit.
Check the contents of special data registers DT9006 and
DT9007/DT90006 and DT90007 and locate the abnormal
intelligent unit. Then check the unit referring to its manual.
Selection of operation status using system register 22:
 to continue operation, set K1 (CONT)
 to stop operation, set K0 (STOP)
E42 I/O unit verify error Selectable I/O unit wiring condition has changed compared to that at time
of power-up.
Check the contents of special data registers DT9010 and
DT9011/DT90010 and DT90011 and locate the erroneous unit.
Then check the unit and correct the wiring.
Selection of operation status using system register 23:
 to continue operation, set K1 (CONT)
 to stop operation, set K0 (STOP)
E43 System watching
dog timer error
Selectable Scan time required for program execution exceeds the setting
of the system watchdog timer.
Check the program and modify it so that FP2SH/FP10SH can
execute a scan within the specified time.
Selection of operation status using system register 24:
 to continue operation, set K1 (CONT)
 to stop operation, set K0 (STOP)
E44 Slave station
connecting time
error for
MEWNET-F
system
Selectable The time required for slave station connection exceeds the
setting of the system register 35.
Selection of operation status using system register 25:
 to continue operation, set K1 (CONT)
 to stop operation, set K0 (STOP)
E45 Operation error Selectable Operation became impossible when a high-level instruction was
executed.
Check the contents of special data registers DT9017 and
DT9018/DT90017 and DT90018 to find the program address
where the operation error occurred. Then correct the program.
Refer to the explanation of operation error and the instruction.
Selection of operation status using system register 26:
 to continue operation, set K1 (CONT)
 to stop operation, set K0 (STOP)
