The OR and ORB instructions are used when at least one of the conditions (here,
two sets of conditions: <0003: ON, 0004: ON>, and <0000: ON, 0001: ON, 0002:
OFF> are given) must be satisfied.
Description
• The OR and ORB instructions are used to connect in parallel the contacts for
these instructions with contacts on the previous line. An LD or LDB instruction is
used together with the OR and ORB instructions.
• As many contacts as desired can be connected in parallel provided they are used
in the same program.
Note: Output circuits (except for and )
cannot be included in the parallel connection.
