Cordsets
Com unit cordset
If two com units are used in a redundant system, they must be connected using a cordset via
the front socket to enable internal data exchange.
Com unit FB8211* has 2 front sockets. The socket with contacts 1 - 8 is used to connect the
com unit cordset. The socket with contacts 9 - 16 is used as a service bus connection.
Com unit FB8210* is not designed for redundancy mode and therefore has no front socket.
Overview of cordsets
Cordset for backplane
The following table shows an overview of possible cordsets. Cordsets establish a local
connection between a base backplane and an extension backplane. If a base backplane is
extended with an extension backplane with additional I/O modules and power supplies, the
backplane cordset ensures data exchange between the com units on the base backplane and
the I/O modules on the extension backplane. The length of the backplane cordset is up to 3 m.
Overview of cordsets
Cordset for gateways
There are two types of cordsets for gateways. One with a wired connection in Ex-i protection
and one with M12 threaded plugs in Ex-e protection. The gateway cordset provides a local
connection between two gateways. If two gateways are used in a redundant system, they must
be connected using a cordset via the front M12 socket or plug to enable internal data
exchange.
Warning!
Explosion hazard through use of incorrect cordset.
The use of incorrect cables in a potentially explosive atmosphere can create sparks that can
ignite the surrounding atmosphere.
