Fieldbus Connection

3.14.1

RS-485-Based Fieldbuses

Connection

The connections for the fieldbus and service bus are equipped with double terminals.

Connect the field bus to the appropriate terminals on the base backplane.

Cable length

Com units can be configured for various transfer rates. The required transfer rate and the bus
system used dictate the maximum cable length.

For standard applications, the technical data for cable type A in accordance with DIN EN 61158
and DIN EN 61784 applies. The following table refers to standard applications.

Danger!

Explosion hazard due to improper installation

Improperly installed fieldbuses can cause explosive mixtures to ignite.

Observe the wiring specifications set out in IEC/EN 60079-14 for laying lines in an explosion-
hazardous area.

Danger!

Explosion hazard due to unapproved accessories

Accessories that do not meet the requirements for use in hazardous areas can cause explosive
mixtures to ignite.

Only use accessories and devices that are approved for use in the respective environment.
