Function
 LD
LD is used for the first normally open bit from the bus bar or for the first normally open bit 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 specification, the status of the CPU Unit’s built-in input terminal is read and
used.
 LD NOT
LD NOT is used for the first normally closed bit from the bus bar, or for the first normally closed bit of a
logic block. If there is no immediate refreshing specification, the specified bit in I/O memory is read and
reversed. If there is an immediate refreshing specification, the status of the CPU Unit’s built-in input ter-
minal is read, reversed, and used.
