PG Interface 20 mA

3.3.5
The programmers PG 635, PG 675, PG 685, PG 695, PG 730 and PG 750 can be connected to
the I P247 at connector X8 via connecting cables (e.g. 6ES5 731- 1.. .0).
Fig, 3/9 Connecting the programmer to the IP247
To set the transmission rate of the programmer (PG), you must connect pins 2, 3, 4, 17 together
in the connector on the PG side (transmission rate 9600 bps). When using standard cables, this
speed is already set.
In the programmable controllersS5-135U and S5-1 55U, you can also use the PG interface via
the backplane bus. To do this, you must insert the module in a suitable slot. The module is then
operated via the coordinator module (for details, refer to the Coordinator Instructions).
