Integration of the ATV312 in a PROFIBUS DP network controlled by a Simatic S7©
PLC IO image / Altivar 312 DP slave mapping
With the Altivar 312 DP slave module:
•The 1st slot defines the addresses of the PKW area, used for parameters management.
•The 2nd slot defines the addresses of the PZD data (control and status of the drive).
The configuration dialog box enables you to define the PEW and PAW assigned to the Altivar 312.
The table below shows this configuration and its pending drive's parameters:
