Action
• Take measures to reduce noise.
• Reset the CPU module, and run it again. If the same error occurs again
even after taking the above, the possible cause is a hardware failure of the
module, base unit, or extension cable. Please consult your local Mitsubishi
representative.

module, base unit, or extension cable. Please consult your local Mitsubishi
representative.
• Check that the inter-module synchronous interrupt program (I44) was
written to the CPU module.
• Set the inter-module synchronization cycle to be longer than the current
value in "Fixed Scan Interval Setting of Inter-module Synchronization"
under "Inter-module Synchronization Setting" in "System Parameter".
• Make the setting value greater than the current setting for "Communication
Period Interval Setting" and "Transient Transmission Time" in
"Communication Period Setting" of the module parameter.
• If the value in 'Transient transmission additional time (calculation value)'
(SW007A) is not 0, add the value (s unit) to "Communication Period
Interval Setting" and "Transient Transmission Time".
• Reduce the number of cyclic assignment points and the number of
connected device stations, and correct the settings so that a shorter value
can be set for the communication period interval setting.
• Do not perform the online change in the CPU module.
• Take measures to reduce noise.
• Reset the CPU module, and run it again. If the same error occurs again
even after taking the above, the possible cause is a hardware failure of the
module, base unit, or extension cable. Please consult your local Mitsubishi
representative.
