co⚡e: Sparkplug™ MQTT edge

v1.4.2.11
Fixed: Time to Wait after a succesful publish (this is a blocking time during which data will not be sent)

v1.4.2.10
Fixed [#136] Edge seems to publish "empty" payloads

v1.4.2.10
Fixed [#136] Edge seems to publish "empty" payloads

[#131] updated example project to the new library version

[#131] v1.4.2.9 fixes issue with skipping DBIRTHs and DDEATHs
incidentally, device messages are now more responsive, as we publish additionally whenever the Node is WAITing for NDATA timer

v1.4.2.8 library changed identity to:
co⚡e: Sparkplug™ MQTT edge and host
CODESYS + MQTT + Sparkplug = 'Plug & Play' IIoT

overhauled and went for an SFC approach

in lieu with cfUnit v1.2

in lieu with cfUnit v1.2

sunk develop branch of unittest

[#129] updated example for new library version 1.4.2.7

[#129] v1.4.2.7 SeqNums : Edge/Device Now successfully publishing with the correct seqnums
Changed SparkplugBSimple to also optionally accept a specific SeqNum

v1.4.2.6
Update: Devices now send DBIRTH, needs further testing/debugging
Check FB_Device.readyForPublish() -> called by: PublisherFound := itfMessageSource.readyForPublish();

v1.4.2.6

The first valid (but yet !UNTESTED!) attempt to let FB_Edge publish the Device Messages via IMessageSource
See statemachine step "PUB_DEV_MSGS"

As said, needs testing/debugging

PrimaryHost: Fixed a bug where you would hit an exception if there weren't enough Host Pool Objects

[#125] Updated example project. Primary host now sends xCMDs.
Note: The Edge Applications are still on an older version of the library, which publishes, but sometimes publishes out of sequence.

[#125] PrimaryHost now publishes NCMDs and DCMDs
Fixed bug with FB_EdgeTopicProvider.SetNCMDTopic
Note: currently only birthed metrics can be xCMDed. A generic xCMD is needed to, for example, send a Node Rebirth to a node which we have not yet received its birth certificate.

[#130] PrimaryHost itterator . Primary Host now itterates all its Edges and devices looking for an xCMD and publishes them

[#130] PrimaryHost itterator . Primary Host can now itterate all its Edges and devices looking for an xCMD

Edge: Fixed Compiler warning about external usage of VAR_IN_OUT for publish period

[#130] FB_RemoteEdge's IMessageSource now offers its own NCMDs as well

[#130] Host Itterator - RemoteEdges implement IMessageSource for their child devices
Still need to implement NCMDs in FB_RemoteEdge's IMessageSource

[#130] Host crawler - implemented IMessageSource in FB_RemoteDevice for DCMD

[#129] Renamed some functions
Corrected GetDBIRTH to GetDDATA

[#129] refactored IAuthor => IMessageSource
fixed IMessageSource method names to have the interface owner as the Subject of the verb
split informPublishDoneOrError() into two properties, PublisherDone and PublisherError
