11-5 CPU Error Indicators
The CPU Unit of the C200H/HS and C200HX/HG/HE PCs has the following indi-
cators to show errors that occur in the Position Control Unit. The errors are indi-
cated for the Position Control Unit as a Special I/O Unit.
11-5-1 Special I/O Unit Error List
Error
Error cause and operation
Remedy
Waiting for Special
I/O Unit startup
There is a hardware fault at a Special I/O Unit.
The PC will not begin operation in this condition.
Replace the Special I/O Unit where the error
occurred.
The faulty Unit will be indicated by a “$**”
character in the I/O Table Read operation.
I/O Unit over
Two or more Special I/O Units have the same unit
number setting. The PC will not begin operation in
this condition.
The Special I/O Unit Error Flag (SR 25415) will be
ON.
Change the unit number settings to eliminate
duplications.
The unit numbers can be listed with the I/O
Table Read operation.
Special I/O Unit
error
Refreshing between the CPU Unit and Special I/O
Unit did not proceed normally. In this case, only
the faulty Unit won’t operate.
The Special I/O Unit Error Flag (SR 25415) will be
ON.
Mounted on the Remote I/O Slave Rack and the
mounting position parameter of the Unit (bits 08 to
15 of m+2) is set to “00.”
With a C200H/HS PC, determine the unit
number of the faulty Unit from flags AR 0000
through AR 0009. Restart the Unit by
toggling the corresponding Restart Bit
(AR 0100 to AR 0109) after eliminating the
cause of the error.
With a C200HX/HG/HE PC, determine the
unit number of the faulty Unit from flags
SR 28200 through SR 28215. Restart the
Unit by toggling the corresponding Restart
Bit (SR 28100 through SR 28115) after
eliminating the cause of the error.
Replace the Unit if it doesn’t restart after
toggling the Restart Bit.
Correct the mounting position and mounting
position parameter and restart.
