PfofiBus Gateway
[10] Port switch
This switch is used to enable the teaching pendant/PC connector (TP) (PORT ON = Start
communication).
Set this switch to the OFF position when connecting/removing the communication cable connector for
teaching pendant or PC software. To use the teaching pendant or PC software, plug in the connector
first, and then set the switch to the OFF position.
(Also check the signal status of the port switching input [4].)
Port switch ON:
Power (24 VDC) is supplied to the teaching pendant. The emergency stop circuit
of the teaching pendant is enabled.
Port switch OFF: Power (24 VDC) to the teaching pendant is cut off. The emergency stop circuit of
the teaching pendant is disabled.
The baud rate between the teaching pendant or PC software and ProfiBus gateway can be set to a
maximum of 115.2 kbps. For your information, the baud rate between the ProfiBus gateway and
controller is fixed to 230.4 kbps.
When the port switch is turned ON, no ProfiBus communication error will generate, but the data
exchange via SIO communication will stop. Accordingly, the PLC’s output signals (data) will no longer
be output to the controller and the input signals (data) from the controller will remain as the values
that were effective immediately before the port switch was turned ON.
A PORT ON status signal (TPC) is output from the ProfiBus gateway to the PLC, so provide an
interlock or other process as necessary.
