Cautions
(1) Even if the dedicated commands (OPEN, CLOSE, BUFSND, BUFRCV) are executed with the
high-speed PLC, the actual operation will take place at the same timing as the medium-speed
PLC. Thus, the dedicated command should be executed with the medium-speed PLC.
(2) If a connection opened with TCP is closed, and is tried to be opened again within a minute, an
error completion (completion status C017) will occur. Wait a while before opening the connection
again.
(3) If the connection No. is not within the specified range, an error completion (completion status
C1A6) will occur, but the completion device and completion device +1 will not turn ON.
