Process Data Objects (PDO’s)
PDO’s are variables continuously transferred between the Device (slave) and the PLC (master)
The PROFINET interface supports only one slot for input and one slot for output.
Each sub-slot can have one register (from the list below) assigned to it. The input slot supports a maximum
of 20 sub-slots. The output slot supports 12 sub-slots. When adding a sub-slot, a list is available (through the
GSDML) with all the available registers. The order in which the registers can be added is not fixed.
Appendix A shows an example in TwinCAT.
This document describes how the data is encoded in the PDO’s. The name of the register corresponds to the
name used in the GSDML. The tables also show the Modbus registers which are linked to the PDO data.
More information about the registers can be found on the Vögtlin website under the download section, look
for digital communication.
