4.5.6 Acyclic Messaging DFBs - Quantum

These following eleven sections provide information about the Derived Data

Types (DDTs) and Variables associated with each of the ten (10) Derived

Function Blocks (DFBs) created by the Application Communication Logic

functions of ProSoft Configuration Builder (PCB) that can be used to send

PROFIBUS DP-V1 acyclic messaging. Your application-specific control and

sequencing logic will use these variables to activate these special functions, if

required, as required, and receive any results that may be returned.

The last item for each DFB topic is a breakdown of the PROFIBUS acyclic

message structure. Creating these messages and handling the responses, if any,

will all be done for you by the provided DFBs. Since each message has its own

unique set of error codes, the primary reason for including this message structure

information is to help you interpret any error codes you may receive as a result of

activating one of these acyclic messages. The eleventh section contains acyclic

message error code information.
