Reset the PLC parameter I/O allocation
setting to conform with the actual status

Reduce the A series special function
modules (except the A1SI61) that can
make an interrupt start to the CPU
module to 12 or less.
Keep the number of special function
modules that can initiate an interrupt
(with the exception of the A(1S)I61
module) to 12 or fewer.
Keep the number of A1SD51S to six or
fewer.
Keep the number of serial
communication modules (excludes
A(1S)J71QU24) installed to six or fewer.
