Special I/O Unit Error Flags These flags are turned ON when there is an error in data
transfers between the PLC and the corresponding Special
I/O Unit or the same unit number has been set on more
than one Special I/O Unit. Each bit corresponds to the Unit

Special I/O Units 0 to 9.)
Special I/O Unit Restart Bits Turn the corresponding bit OFF→ON→OFF to restart a
Special I/O Unit. Each bit corresponds to the Unit with the
same unit number.
(Bits SR 28100 to SR 28109 can also be used to restart
Special I/O Units 0 to 9.)
