There is no priority in the error codes; all errors will be displayed in the order
they occur. All error codes consist of a combination of a letter and a number,
so they can be distinguished from the other state indications immediately.
The unit number is used to identify individual CPU Bus Units mounted on a
PLC. The unit number must be unique for each CPU Bus Unit. Selecting a
non-unique number for a CPU Bus Unit will prevent the PLC System from
starting correctly.
