The PROFIBUS PA connections for the ST100 are located in
the back panel. The connector pins are labeled “A(+) Pin #2”
and “B(-) Pin #3”. The ST100 PROFIBUS PA connections are
non-polarized, but polarity needs to be observed for other
manufacture’s devices. Connect the Field bus cable as noted
below.
In addition to the PROFIBUS PA connections in the back
panel, the ST100 also has a series of jumpers used to select
other digital communication protocol. Confirm that FF+/PA+
and FF-/PA- have the shorting jumper installed, this select
the output pins for the PROFIBUS PA digital protocol.
Topology and Network Configuration
The ST100 supports both Bus topology and Tree topology. Both types have a trunk cable with two terminations. The devices are connected to the
trunk via spurs. The spurs may be integrated in the device giving zero spur length. A spur may connect more than one device, depending on the
length. Active couplers may be used to extend spur lengths.
Active repeaters may be used to extend the trunk length.
The total cable length, including spurs, between any two devices in the Fieldbus should not exceed 1900m. The connection of couplers should be
kept less than 15 per 250m.
