Detailed Description

Processimage synchronisation via Modbus/TCP.

This device is derived from the signal based sDevice to read and write line levels via ethernet using the Modbus/TCP protocol; see also the Modbus Organization.
When configured as master, the mbDevice initiates commucation with a specified list of slaves in order to retrieve input line levels and to set output line levels. The latter are locally buffered and are propagated to the event-based interface inherited via the base class sDevice. When configured as slave, the mbDevice accepts connections from any Modbus master, will response to their request sand update the local line-level buffer accordingly.

Further dedatils on the configuration, incl. an example, are provided by the ModbusDevice user-reference

Technical details.

The mbDevice slave implements reading and writing bits/coils/registers/holding registers, incl. the multi-read/write variants; regardless which commads you use, they all refer to the one process image implicitly defined by the event configuration.
The mbDevice matser usees the commands read multiple bits and write multiple coils for process image synchonisation.
All network communication come with quite relaxed timeouts. Please let us know, if you require more strict timeout behaviour.
Network communication is currently implemented synchronous with the edge detection background task; this is restrictive and may be changed in future revisions.
Communication uses an additional line-level buffer; a better solution would be to share the line buffer with the sDevice; however, this is not supported by the current sDevice interface.
Programatic configuration is still incomplete.
The mbDevice compiles with MinGW/Windows, however, it was not properly tested in this configuration; please let us know, if you plan to use mbDevice in a Windows context.

Note: This device must be explicitely enabled in Makefile.plugin.
