Acyclic Data Transfer Via PROFIBUS DP
Acyclic data exchange takes place between the ET 200iSP and the PG / PC (SIMATIC PDM).
The ET 200iSP receives its parameters using acyclic data exchange. Identification data is also
transferred and displayed in SIMATIC PDM.
● Diagnostics and interrupts (with S7 DP slave and DPV1 slave)
● Data records
DPV0, S7 DP, or DPV1 slave
The ET 200iSP can be operated as a DPV0, S7 DP or DPV1 slave. The following table
compares the functions.

Interrupts
● Diagnostic interrupt
● Hardware interrupt
● Remove/insert interrupt
● Update interrupt
● Time stamping
If you configure the ET 200iSP using the GSD file (in HW Config), you will need SIMATIC PDM for
1
parameter assignment.
For the S7 DP slave, diagnostic and process interrupts are only reported when the CPU is in RUN
2
mode.
