4.4.6 Acyclic Mailbox Message DFBs -M340
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.
