4 Protocol 3100
4.1 Process Data Objects
The Process Data Objects (PDOs) are used for the high-speed
exchange of process data.
In this chapter, you will find a description of the Process Data
Objects that are cyclically sent from the ekr 500 digital Unit Touch
web guiding controller to the customer control system.
For the exchange of process data, the protocol 3100 supports
three Transmit PDOs (Tx PDOs). The Process Data Objects are pre-
configured for standard applications in the factory and cannot be
changed.
