The following ladder program example shows how to return the Serial Gate-
way to the not prohibited status when the PMCR(260) instruction has been
executed and the sequence is completed. (This example uses port number 1
of a Serial Communications Unit with unit number 0.)

When execution condition W00000 is ON, the Serial Gateway Prohibited Flag
(port 1: Word n, bit 04: CIO 1500, bit 04) turns ON and the Serial Gateway is
prohibited.
At the same time, bit 00 of W000 is shifted one bit to the left.
When W00001 is ON, the Communications Enabled Flag for port No. 0
(internal logic port) is ON, and the Protocol Macro Executing Flag (port 1:
Word n+9, bit 15: CIO 150915) is OFF, the PMCR(260) instruction
executes.
At the same time, bit 00 of W000 is shifted one bit to the left.
When W00002 is ON, the sequence ends, and the Protocol Macro Executing
Flag (port 1: Word n+9, bit 15: CIO 150915) turns from ON to OFF, the Serial
Gateway Prohibited Flag (port 1: Word n, bit 04: CIO 150004) is reset to 0,
and the Serial Gateway is no longer prohibited.
