STB NIB 2212 Fieldbus Interface
Summary
The fieldbus interface on the STB NIB 2212 is the point of connection between an
Advantys STB island bus and the INTERBUS network. Like every INTERBUS node,
the NIM has two nine-pin SUB-D connectors for data reception (in) and transmission
(out). The connectors are located on the face of the NIM.
Fieldbus Port Connections
The in and out fieldbus interfaces are located on the front of the INTERBUS NIM at
the top:
It is recommended that you use 9-pin SUB-D connectors compliant with INTERBUS
Club or corresponding international standard.
The in connector is optically isolated. The signal level is according to EIA RS-485.
The pin-out for both the in (upper) and out (lower) connectors should be according
to the table below (pin numbers correspond to callouts in the figure above):
