@brief The PlcLinkWidget class

Provides a dedicated widget for linking a PLC-Slave to a PLC-Master IO entry.
|
|
Displays all PLC-Masters as expandable items, each showing their IO entries.
|
|
Each IO entry can only be linked to one slave. Already-linked entries are
|
|
shown as struck-through and greyed out.
