Name Value Specification 1 Shield - Cable shield 6 +5V +5 V +5V output 1) 2 - - Not used 7 - - Not used 3 RxD / TxD-P B-line transmission / reception data 8 RxD / TxD-N A-line transmission / reception data 4 RTS / LWL Request to Send 2) 9 - - Not used 5 GND5V 0 V Reference potential GND 5V 1) 1) Can be used for external bus termination or to supply the transmitter/receiver of an optical waveguide transmission. 2) The signal is optional. It is used to identify the direction of an optical waveguide connection. 11.1.3.2 Mating connector � 9-pin DSUB connector, e.g. Erbic MAX Profibus IDC Switch, made by ERNI 11.1.3.3 Cable type and configuration The cable names given refer to cables made by Lapp. They have proven to be reliable and are successfully used in many applications. However, it is also possible to use comparable cables from other manufacturers, e.g. Lütze or Helukabel. � LAPP KABEL UNITRONIC BUS L2/FIP FC; 1 x 2 x 0.64; ∅ 7.8 mm, with tinned CU shielding for quick-connect applications with IDC connectors 138 E 732 GB 14.12.2006

The bus termination has to be provided at the beginning and at the end of every bus segment. Most PROFIBUS connectors come supplied with integrated terminating resistors. For bus connections with connectors without integrated terminating resistors, the PROFIBUS-DP interface has its own terminating resistors. They can be activated with the help of the two DIP switches on the module (switch set to ON). To ensure safe operation of the network, only one bus termination may be used at a time. The external connection can also be set up discretely (see Figure 35). The power supply of 5 V required for the externally connected terminating resistors is supplied at the PROFIBUS connector of the PROFIBUS-DP interface (see pin assignment in Table 48).
