[9] Port switch
This is a switch to enable the connector (T.P.) for teaching box and personal computer (PORT
ON=Communication start).
When connecting and disconnecting the teaching box and the communication cable connector for
personal computer supporting software, turn OFF this switch. When using this switch, turn ON after
connecting the connector.
(Also pay attention to signal status of the port switching input [4].)
For communication rate between the teaching box, personal computer supporting software and the
CC-Link gateway, up to 115.2kbps can be set. And, the communication rate between the CC-Link
gateway and the controller is fixed to 230.4kbps.
When the PORT is ON, the CC-Link communication does not become abnormal, however, data
communication for SIO communication stops. Therefore, output signal (data) from the PLC is not
outputted to the controller, and input signal (data) from the controller keeps a value immediately before
PORT was ON.
PORT ON status signal (TPC) is outputted from the CC-Link gateway to the PLC, therefore, performs
processing such as interlock if necessary.
