3.1.8.4.1 Transmission via the Serial Interface
Use the WAGO communication cable to produce a physical connection to the
serial interface. This is contained in the scope of delivery of the programming
tool IEC 1131-3, order No.: 759-333/000-002, or can be purchased as an
accessory under order No.: 750-920.
Connect the COMX port of your PC with the communication interface of your
controller using the WAGO communication cable.
Warning
The communication cable 750-920 must not be connected or disconnected
while the coupler/controller is powered on!
A communication driver is required for serial data transmission. In
WAGO-I/O-PRO CAA,
this driver and its parameterization are entered in the
"Communication parameters"
dialog.
