Conversion Data Does
Not Change
There are two ways to restart Special I/O Unit operation after having changed
DM contents or having corrected the cause of an error. The first way is to power
up the PC again, and the second way is to turn the Special I/O Unit Restart Bit
ON and then OFF again.

Note SR bits 28210 to 28215 cannot be used with C200HE and C200HX/HG-
CPU3j-E/4j-E PCs.
If the error is not cleared even after turning the Special I/O Unit Restart Bit ON
and then OFF again, then replace the Unit.
The following tables explain the probable causes of troubles that may occur, and
the countermeasures for dealing with them.
Probable cause
The input is not set for being used.
The peak value function is in
operation.
The input device is not working, the
input wiring is wrong, or there is a
disconnection.

Countermeasure
Set the input to be used.
Turn off the peak value function if it
is not required.
Using a tester, check to see if the
input voltage or current is
changing.
Use Unit's error codes to check for
a disconnection.
