Область применения

Communication modules connect the controller with an external communication partner to exchange data.
Comprehensive parameterization options make it possible to adapt the controller flexibly to the communication partner.
Modbus RTU master creates a Modbus RTU network for up to 30 Modbus slaves.

Дизайн

Usable BaseUnits

The standard BaseUnits of the ET 200SP are available for connection. The individual signals of the serial connection are connected with appropriate terminals.

A light BaseUnit opens a new load group. The power supply must be fed in via this BaseUnit. The first BaseUnit next to the interface module must always be a light BaseUnit.

A dark BaseUnit forwards the power supply of the adjacent light BaseUnit on the left via self-assembling voltage buses. A new infeed is therefore only required on the next light BaseUnit to the right.

All variants that correspond to BaseUnit type A0 can be used as BaseUnits.

System-integrated shielded connection

For a space-saving and EMC technically optimized connection of cable shields, a shield connection is available that is quick and easy to mount. This consists of one shield connection element that can be plugged onto the BaseUnit and one shield terminal for each module. The low-impedance connection to the functional ground (DIN rail) is carried out by the user and requires no additional wiring.
