3.6 Profibus Port
The Profibus RS485 connector is a D9 connector in the top end-plate of the module (see below).
105G-PR1 (Profibus Slave) End Plate:
Note: If the “Use Rotary Switch Address” option in configuration software is selected, the two
rotary switches are used to specify the Profibus Node Address in the range 0 – 99. In this case,
the value on the left switch is multiplied by 10 and added to the value on the right switch to give
the node address.
Where the 105G module is mounted at the end of the RS485 link, the RS485 link should be
terminated by switching the termination switch “on” (down in the above diagram).
105G-PR2 (Profibus Master) End Plate:
For the Profibus Master 105G a second, unused, connector is also present.
The Profibus RS485 connection should be made to pins 3 and 8 of the Profibus D9 connector.
The pinouts for this connector are:
