DPV1 Messaging
This section describes DPV1 messaging functions supported by the PROFIBUS
Slave module.
Note: Every DPV1 read or write request has to be acknowledged by the PLC application program.
Otherwise the PROFIBUS master shuts down communication for both channels, V0 (cyclic IO
data) and V1 (non-cyclic messages). This can cause unexpected lost of data between the master
and the PS69-DPS slave.
DPV1 Class 1 Read Response
The DPV1 Class 1 Read Response message is used by the Slave to reply to a
Master DPV1 Read Request. The MSG instruction Request/Confirmation format
is as follows.
