25: Unit error
02
Parity/checksum error occurred
because of incorrect data.
Transfer correct data into memory.
03
I/O setting error (The registered I/O
configuration differs from the actual.)
Either change the actual configuration to
match the registered one, or generate the
I/O table again.
04
Too many I/O points
Redesign the system to remain within
permissible limits.
05
CPU bus error (An error occurred
during data transfer between the CPU
Unit and a CPU Bus Unit.)
Check the Unit, Service Boards, and cable
connections and issue the ERROR CLEAR
command.
06
I/O duplication error (A rack number,
unit number, or I/O word allocation
has been duplicated.)
Check the system’s settings and eliminate
any settings that occur twice.
07
I/O bus error (An error occurred during
data transfer between the CPU Unit
and an I/O Unit.)
Check the Unit, Service Boards, and cable
connections and issue the ERROR CLEAR
command.
09
SYSMAC BUS/2 error (An error
occurred during SYSMAC BUS/2 data
transfer.)
Check the Unit, Service Boards, and cable
connections and issue the ERROR CLEAR
command.
0A
Special I/O Unit error (An error
occurred during CPU Bus Unit data
transfer.)
Check the Unit, Service Boards, and cable
connections and issue the ERROR CLEAR
command.
0D
Duplication in SYSMAC BUS word
allocation.
Check and regenerate the I/O table.
0F
A memory error has occurred in
internal memory, in the Memory Card,
or in Expansion DM during the error
check.
If the error occurred in internal memory or
the EM Unit, correct the data in the
command an execute it again.
If the error occurred in a Memory Card or
EM used for file memory, the file data has
been corrupted. Execute the MEMORY
CARD FORMAT command for the PC.
If the above remedies do not eliminate the
error, replace the faulty memory.
10
Terminator not connected in SYSMAC
BUS System.
Connect the terminator correctly.
