Details for Operating Compact HMI SCADA on Client PC, through Server using Softcontroller
Hello Stefan Sir,
I have Compcat HMI 5.1 and Control Builder on my Laptop.
And on another system we are building a software,which will pick the OPC data from my laptop on LAN basis.
We have planned first to do this by using SoftController on my Laptop.
Ahead, I successfully entered and operated SCADA screens through control builder on my laptop using softcontroller. ( I kept Controller IP: 192.168.1.48:2 and My ethernet IP as 192.168.1.48)
But, if keeping my Laptop as client, and that other PC as Server. I want that SCADA on my laptop should be controlled by Control Builder on that other PC (server).[ through softcontroller only ]
So, what exact steps are there for setting connection between them ??
Like when having real physical Controller Module,if we set IP as 172.16.4.1 , then we use server PC or client PC on LAN as 172.16.4.11 ; ....... 172.16.4.12 ;.....and so on !!
So ,if we set here on SoftController IP as , 192.168.1.48:2; and my Server Pc as 192.168.1.48; so what will be my Client Laptop IP(which is having SCADA) in relation to SoftController/Server PC IP ??
Secondly, on Control Structure where should I make changes for this Softcontroller work(( on PLC Connect Servers,PLC generic control network, etc )). Please mention in detail for this part !!
Thanks in advance
I don't have enough time to take screenshots of every step required - I'm also a bit suspicious about configuring a laptop acting as a server to a professional control system. But if I were to ignore that fact; you should be able to connect to the soft controller in your laptop from any node on the network, just add the MMS process number suffix :2 as you have made yourself.
The IP-address of your laptop must be routable from the system it shall communicate with; either by assigning it with the same network ID of that system (e.g. 172.16.x.48) or be setup with static routing or default gateway. Several options exist, but I recommend putting it on the same subnet but with a unique IP-address. RNRP is optional (but still recommended) if only MMS traffic is to be routed.
About Control Structure; a CHMI project does not need to be visible there. If only controller to controller traffic is expected (MMS read/write of Access Variables or perhaps even IAC) you do not need to inject the soft controller into the structure.
Anyhow, if you want to use PLC Connect to communicate with the soft controller you must add it using standard procedures (create new controller in PLCC, setup communication parameters, perform PLC Upload and last deploy the network into the PLC server).
