If input condition CIO 000000 is ON, Communications
Port No. 0 Enabled Flag A20200 is ON, and Protocol
#02E1
Macro Executing Flag CIO 191915 is OFF, then se-
quence No. 000 is executed for Serial Communications

If Protocol Macro Executing Flag CIO 191915 turns OFF,
CIO 000100 turns ON (and remains ON for one cycle).
If Protocol Macro Executing Flag CIO 191915 is OFF
and Step Error Processing Flag CIO 191914 is OFF
D00201
when CIO 000100 turns ON, then the received present
value in DM00201 is moved to DM00300.
D00300
If CIO 000100 is ON (sequence end) and Step Error
Processing Flag CIO 191914 is ON, the sequence ends
abnormally and a FAL(06) instruction (Non-Fatal Diag-
nostic Instruction) is executed.
If the Communications Port Error Flag for port 0 turns
ON, a FAL(06) instruction (Non-Fatal Diagnostic Instruc-
