Please note
S Please refer to the PLC manual or the manual for your
module /scanner for the correct type of cable. Take
into account the distance and the baud rate selected.
S Select the appropriate cable cross-sectional area.
Note the voltage drop in the supply line for the bus
interface and the internal logic.
Caution
S Make sure of the correct polarity when connecting
the field bus interface and the power supply for the
bus interface/logic.
S Connect the screening.
If the SPC200 is at the end of the field bus, a terminating
resistor (120 Ohm, 0.25 Watt) must be fitted between the
cores Data + (pin 4) and Data - (pin 2) of the field bus plug.
If you are using T-adapters, we recommend that you fit the
terminating resistor on the unused output of the T-adapter.
