H
System error (The OS detected an error.)
• Follow the procedure below.
(1) Check if the Ethernet module, the power supply
module, and the CPU module are properly connected.
(2) Check if the operating environment of the Ethernet
module conforms to the general specifications of the
CPU module.
(3) Check if the power capacity is sufficient.
(4) Check if the hardware is normal according to the
manual for each module.
If the actions above do not solve the problem, please consult
your local Mitsubishi representative.
