AND NOT is used for a normally closed bit connected in series. AND NOT
cannot be directly connected to the bus bar, and cannot be used at the begin-
ning of a logic block. If there is no immediate refreshing specification, the
specified bit in I/O memory is read. If there is an immediate refreshing specifi-
cation, the status the Basic Input Unit's input terminals is read.
There are no flags affected by this instruction.
Immediate refreshing (!) can be specified for AND NOT. An immediate refresh
instruction updates the status of input bit just before the instruction is exe-
cuted from Basic Input Units (but not for Basic Input Units on Slave Racks or
for C200H Group 2 Multi-point Input Units).
