800xA OPC Server Network
What is the difference between "Generic OPC Server Network" and "PLC Generic Control Network" ?
Voted best answer
Generic opc acts as both server and client and is intended when small amount of opc items are required read and write but you need to create opc property individually under control connection aspect and if u need alarm then you have to depend on alarm expression(soft alarms).
This is generally used bet xa and any 3rd party opc or in between xa systems and this is license free
PLC generic control network is derived from PLC connect package n it has its built in opc DA/AE and has its own aspect objects so easier to configure by instantiating it's aspect objects .
Generally PLC connect supports opc client,modbus drivers this is a licensed one
The sooner (Generic) is part of 800xA Base. Involves one OPC DA Connector service provider. Deliver an "Untyped solution" after upload (all uploaded objects become "Generic OPC Object"). No built-in alarm feature, alarm expressions are required for alarm.
The latter is part of PLC Connect. The tags are added a bit differently, additional (PLC Connect) services needs to be added apart from installing the PLC Connect system extension. PLCC support object types. PLCC can also provide "PLC soft alarms" to 800xA over OPC AE. Just as for Generic OPC System 800xA connect to the PLCC server via an OPC DA Connector.
