How can I connect more than 10 operator stations to a single Freelance controller?
Voted best answer
There are a couple ways this can be addressed.
1. Add 800xA Operations on to the existing Freelance system. You can configure well over 10 stations using 800xA Operator Clients while only using 1-2 controller connections (single or redundant OPC Gateways). Plus, you get the advanced functionality of 800xA Operations.
2. A less costly method is to use the Freelance PLC Integration option. Use one controller connection for an OPC Gateway and connect it to the Freelance OPC Server. This will allow the controller to pass data to >10 DigiVis stations via OPC.
The question is to have more than 10 Operator stations for a single controller - such case does not happen in real projects... but the common case is to have:
Example1: Production line 1, Production line 2, and Production line 3 and a need of 20 Operator stations
Example2: One large factory with pre processing, main processing and post processing - again a need of let say 20 Operatory stations
In such scenarios we would have minimum 3 process areas and at last 3 controllers.
a single click of a mouse disables/enables communication between controller and DigiVis
-> go to CBF -> System menu -> Communication configuration
configure in a way that you will have:
5 OSes for area1 only,
5 OSes for area2 only,
5 OSes for area3 only,
5 OSes for ALL areas - global stations.
Such type of configuration to have local and global stations is well accepted by customers.
The below picture shows default configuration of communication - global OPC servers and global Operator stations - getting all data from all controllers
The next picture shows how to create local operator stations
and finally a screenshot of the system consisting of
2x Global OPC servers (that can be connected to 800xA to make even more global operator stations)
4x Global Operator Stations
4x Local for CPUs 1,2&3
4x Local for CPUs 4,5&6
4x Local for CPUs 7,8&9
4x Local for CPUs 10,11&12
all together 20 Operator stations and 2 OPC servers
