Profibus DP Mk2 Option Card Installation Manual 4.5 Cable Types The network must be connected using a suitable cable. Two conductors plus a shield are required and there is a Profibus specification for the cable. Type A cable should be used for all new installations. Amongst the cable manufacturers Belden have the PVC jacketed 3077F single pair 2 core cable, which meets the minimum requirement. Information on Belden cable may be found on the Belden web site (www.belden.com). Belden 3077F Data Pair Screen Type A Profibus DP Cable Specification (for all new installations) Impedance 135 up to 165 ohm at a frequency of 3 to 20 MHz Cable capacitance 0.34 mm2 (corresponds to AWG 22) Cable type Twisted pair cable, 1x2 or 2x2 or 1x4 lines Resistance
Txd/Rxd - N Txd/Rxd - P Single and Dual Data Highway Configurations 4.7 Inter-connecting the Highway and Setting up the Profibus Card The Profibus Mk2 variants allow for different highway connections. The ‘single channel’ can be used for simple highways, and where there is an analogue transmitter connected it will also return the value from the transmitter signal. The ‘dual channel’ (both Simple and RedCom compliant) is used for redundant highway applications where the highway integrity (SR mode) or the physical connection is important (FR mode). 4.7.1 Single Highway with Analogue Input PLC/ Host r + Actuator 1B In Out L2 1A In Out L1 Data Highway r - Terminator r + Actuator Fit L1 and L2 on the last actuator 1B In Out 1A In Out L2 L1 Analogue Input 4-20 mA I/P A Tx I/P B Common + Tx Power Supply - r - Fig 15: Single Highway + Analogue Connections With the single channel option the actuator is connected to only one highway and an additional input is provided for measuring and reporting an analogue variable. The connection of the actuator to the highway uses terminals 1A and 1B (in and out terminals), the terminal numbers depend on the actuator type and are indicated on the actuator wiring diagram. The highway should be arranged so as to eliminate any stub connections. The last actuator on the highway should have the termination resistor connected by linking the highway 1B terminal to the Terminator terminal and fitting the internal links LK1 and LK2 in the Terminate position. Take care to ensure that the correct polarity is observed on the data highway connection, all the 1A terminals must be used on one data line and all the 1B terminals on the other. 23 of 66 Publication S420E V3.0 Issue 01/05
