Introduction to PROFIBUS DP-V1
Functions of PROFIBUS DP-V1
11.1.4 DP-V1 services
The DP-V1 expansions offer new services, which can be used for acyclical data
exchange between master and slave. The system distinguishes between the following
services:
11.1.5 DP-V1 alarm handling
In addition to the acyclical services, the DP-V1 specification also defines extended
alarm handling. Alarm handling now distinguishes between different alarm types. As a
result, unit-specific diagnostics cannot be evaluated in DP-V1 operation using the
"DDLM_SlaveDiag" DP-V0 service. DP-V1 alarm handling has not been defined for
drive engineering as an inverter does not usually transfer its status information via
cyclical process data communication.
