The 07 KP 53 MODBUS coupler, connected to the 40/50 series basic unit, provides the two additional communication ports COM3 and COM4. These ports could be used with RS-232 for point to point communication or with RS-485 for network communication. COM3 is at the top, COM4 at the bottom of the coupler.
- RS-232: 8-pole Mini-DIN plug, for pin assignment see one page before. The available cables 07SK50, 07SK51, 07SK52 and 07SK53 can be used.
- RS-485: Connection via two removable 3-pole terminal blocks. At the coupler side, the terminals are circuited in parallel. This enables an easy network cabling. The terminals are suitable for wires up to a cross section of 2.5 mm2. The recommended tightening torque is 0.5 Nm.
The MODBUS network is established with shielded and twisted pairs (with a cross section of 0.22 mm2 per wire, for instance).
The shield (preferably braided) is connected to earth near the coupler (< 1 m cable length).
