Connecting neighboring controllers

Example 10

Assign the inputs of the MasterStateMachine to the PD interface without changing anything in the function block itself.

Solution

A fieldbus master can be connected in two ways. Either via direct PD mapping or via PD mapping of the logical device.

With direct PD mapping, the fieldbus data is connected directly to the variables. This solution is useful as long as no logical device is created for the fieldbus and therefore cannot be used together with MOVIKIT "PD ready" in the same project.

In MOVISUITE^®, the system calls are deactivated.

The process data is available via the global variables.

The easiest way is to assign the inputs of the machine module directly to the fieldbus data.

This solution is very efficient and is recommended as long as no logical devices are used in the project.

The connection with the logical device via PD mapping is more complex and is not described in this manual.
