2.4.6.9. PROFIBUS PLC Option (Harsh Enclosure)
The PROFIBUS PLC option board (Figure 2-115) is installed in position 3 (Figure 2-94) on the
main board. Connection to the PROFIBUS board in the harsh enclosure (Figure 2-115) is made
using a right-angle nine-pin connector inside the IND570 enclosure. This connector is a standard
Siemens part # 6ES7 972-0BA12-0XA0 or equivalent. It is not supplied by METTLER TOLEDO.
There are two nine-pin connectors on the PROFIBUS board – use the connector and cable routing
shown in Figure 2-116. Refer to Figure 2-114 for the PROFIBUS nine-pin connector assignments
and follow the wiring instructions included with the connector to terminate the wires.
