  • Page 12: Application

    – DP master mode for DP slaves according to PROFIBUS DP-V0 and DP-V1 – DP master mode for Siemens DP slaves – Direct data exchange (DP slave to DP slave) As a DP master, the CM 1542-5 is capable of enabling direct data exchange for its assigned DP slaves. – SYNC/FREEZE The outputs or inputs can be synchronized by the user program using system function DPSYNC_FR.

  • Page 13: Further Functions

    Data records from devices that are not connected directly to PROFIBUS and therefore have no direct access to the DP slaves are forwarded to the DP slaves by the CM. The services of the CM 1542-5 listed above can be used independently at the same time. Note...
