Connection
5 Connection
X310
The X310 (9-pol D-Sub) bus connector is occupi
to the Profibus-DP-Norm EN50170.
See the following table for details of the pin assignment.
The bus termination necessary on the bus line in the physically first and last sub
via corresponding circuits in the bus connection sockets (e.g. built by Siemens).
Attention! The device will only communicate with the master if
− the master is connected to the mains (or powered by 24V DC)
− the device is connected to the mains (or powered by 24V DC)
− the first and the last subscriber on the connected branch have a correctly set bus
termination
− all other devices in between have no bus termination or a deactivated bus
termination.

4 CNTR-P control signal for Repeater
5 DGND isolated Ground Connection for Bus Termination
6 VP isolated 5V for Bus Connection

Only admissible types ar
e to be used for the bus socket. They must all be suited for the 12 MBaud
transmission rate.
This is, for example, type Profibus connector 12 MBAUD (6ES7 972-0BA11-0XA0) from Siemens.
Only admissible types are to be used as a line for the Profibus (line type A).
This is, for example, type UNITRONIC-BUS L2/F.I.P. 1x2x0,64 from Lappkabel.
Attention! The line screen is to be connected to ground (PE) on both sides with good conductivity.
