KEEP
a (Executing)
The explicit message instruction is executed when a (executing)
turns ON. The port number 0 is specified.
Explicit

instruction
The Communications Port Enabled Flag (A202.00) is OFF during
Port: 0
network communications and turns ON when they are completed
(for either normal or error completion).
d (Execution completed) is turned ON when a (Executing) turns
ON and the
ON.

a (Executing) is turned ON and held ON when the
execution condition and Communications Port
Enabled Flag (A202.00) turn ON.
a (Executing) is turned OFF when d (Execution
completed) turns ON.

d (Execution completed)
If the Explicit Communications Error Flag
(A213.00) when execution is completed, explicit
memory communications were completed
normally and normal processing after network
communications is performed.
If the Explicit Communications Error Flag
(A213.00) is ON when execution is completed, an
error has occurred in explicit message
communications and the Communications Port
Error Flag (A219.00) is checked. If it is OFF,
processing for an explicit communications error is
performed on the assumption that an explicit
message was sent and an explicit message
response was received.
If the Explicit Communications Error Flag
(A213.00) is ON when execution is completed, an
error has occurred in explicit message
communications and the Communications Port
Error Flag (A219.00) is checked. If it is ON,
processing for a FINS communications error is
performed on the assumption that an explicit
message was never sent.
