  ACyCLIC COmmUNICATION 

The INTELLIBUS supports acyclic communication (extension V1 of the Profibus protocol) which  

allows to read the actuator’s state, to read all its configuration. It can be also reconfigured through 

the V1 extension.

There is two type of master in the acyclic communication:

-  The master class1 which supports cyclic communication. It is normally the same PLC which 

manages the actuators.

-  The master class2 supports all the acyclic communication. It can be included to Profibus  

without interference. A laptop equipped with a Profibus module and PDM software may be used  

as a master class2 anywhere on the line.

The INTELLIBUS supports the Read and Write messages  

of the master class1 (MSAC1_Read, MSAC1_Write).

For master class 2, this interface supports Initiate, 

Abort, Read and Write services. Interface board supports  

a maximum of 2 simultaneous class2 master connections.

We advise to use PDM Siemens software to read and 

configurate the actuators with a master class2. We can 

give you an Electronic Device Description (EDD) which 

allows you to manage our actuators with PDM.

With PDM and this EDD you can configure and parameterise  

the actuators and also recover information for diagnostics  

and maintenance.

For example, alarms, activity, torque curves…

To use PDM, not straight to the fieldbus but above  

the PLC then the PLC must be Siemens S7 400 series.

In case of a redundant system, the connection of PDM 

to one fieldbus line, will collect all data including those 

communicating on the other line.
