Probus DP V1 and Probus PA buses
Probus Remote Master module
Probus DP eldbus
Probus DP is one of the most widely used eldbuses in industry. Based on a
master/slave protocol, only master stations, sometimes called active stations, have
the right to access the bus, with slave, or passive, stations being limited to
responding to interrogations.
Version V0 of Probus only allows cyclic exchanges with I/O, whereas version V1
offers an acyclic message handling channel that can be used for device adjustment
or diagnostics during operation.
The physical link is a single shielded twisted pair, but numerous interfaces are
available for creating all sorts of topologies - tree, star, or ring - including those using
optical ber or a non-physical link.
Gateways can be used to communicate transparently with Probus PA, one of the
most commonly used standards in process applications for connecting
instrumentation. Probus PA can be used to supply devices across the network and
also to install sensors in potentially explosive zones (ATEX).

Probus Remote Master (PRM) module
Presentation
The Probus Remote Master (PRM) module is connected to the Ethernet Modbus
TCP/IP network via its integrated 2-port switch, as close as possible to the process
and the instrumentation.
The PRM module can be used to connect Modicon Quantum, Premium, M580, and
M340 PLCs to Probus DP V1 via the I/O scanner function.
Irrespective of the type of PLC, only one product reference is required and setup is
identical, thus reducing training and maintenance costs.
Two versions are available, standard and tropicalized, so as to adapt to any type of
environment.
The PRM module is open to Asset Management tools. A dedicated communication
DTM is supplied with the product, thus allowing any compatible FDT standard tool to
remotely adjust devices on Probus using Ethernet.
Conguration
From a single Unity tool, the user can create the Probus conguration, the PLC
application, and congure or calibrate devices.
The latter are integrated in the Unity catalog via their DTMs if they exist, or their gsd
les.
The I/O scanner conguration is created implicitly in Unity Pro using the Probus
conguration. The parameters assigned by default help optimize performance, as well
as the consistency of I/O data in the PLC application, irrespective of the PLC
platform.
Similarly, the I/O variables dened and presymbolized in the DTMs can be used
directly in the application. Finally, the screens integrated in Unity Pro, together with
the diagnostic functions integrated in the device DTMs simplify application
maintenance.
