TeSys-U

conguration

principle

The TeSys-U in this case is connected to Ethernet through an Advantys STB island. The connection can be

done either using a pre-wiring solution or an inter-segment Advantys solution.

The conguration of motor starter data used behind an Advantys STB required two steps:

In the rst step the data exchanged between Advantys STB and PLC must be congured in I/O scanning v

service. All Advantys I/O image is exchanged during this stage.

In the second step the data of the selected Motor starter is identied inside the Advantys I/O image. v

The goal is to assign a dedicated DDT to this starter.

First step: I/O scanning conguration of the STB island b

Unity I/O scanning service conguration is done from the Modbus image provided by Advantys STB.

The Input base register of the Advantys Modbus image is used to ll the RD slave index of the I/O scanner

(Read). In the same way, the output base register is linked to the WR slave index (Write). A rst additional regis-

ter is used for diagnostic purposes.

4-Conguration

PLC and motor control device conguration

In the following example the I/O scanning service periodically reads the Modbus image of Advantys STB and

stores the data from %MW599.

In the same way, data from MW%660 from Unity Pro is written to the output area of Advantys Modbus image.

Between PLC data and Advantys data a difference of one address must be taken into account during

I/O scanning conguration.
