The field bus is a standard field bus which allows a PLC to be connected to various other components of a control system (IP20 TBX modules and IP65 TBX modules, ATV and Momentum variable speed drives, Magelis terminals, etc.), including sealed I/O modules.
The Fipio field bus is made up of one or more sections interconnected by repeaters. The maximum length of a bus segment is 1000 m. The use of electrical or optical repeaters enables the length of the bus to be increased to 15 000 m.
Without repeaters, up to 31 IP67 sealed I/O modules can be connected with a remote‐power supply over a maximum distance of 1000 m.
Using electrical or optical repeaters, it is possible to connect up to 98 IP67 sealed I/O modules over a maximum length of 15 000 m.
Devices may be connected to a segment:
-
by linking, each element is simply connected to the previous segment by the cable, this is the case for an electrical point-to-point link,
-
by branching, each device is connected by branching on the main cable. A branch consisting of several devices can be created to control a geographically localized assembly,
-
by a mixed topology which enables equipment to be connected by both linking and branching.
For all such cases, the length of each section must be checked to ensure that it is compatible with the correct operation of the assembly.
