The company I work for have a large number of Schneider PLC's across a number of different sites and the engineers in charge of them are hoping to simplify the process of retrieving force data.
Unity Pro is really lacking in this area, to retrieve this data involves loading up the project running on that plc, connect to it and then click the red [F] icon in the bototm right hand corner of the application screen.
I've tried analyzing the modbus tcp traffic in the hopes of retrieving this but have learned two prohibitive factors:
1. There is a huge amount of data being exchanged between Unity and the PLC every second, and;
2. Schneider use a single function code, 0x5A (90) and then encapsulating everything within sub commands etc. I presume this is to prevent direct access to the memory registers.
So I'm wondering if there is any sort of software that will retrieve forced variables and their values in an easier way? Preferably something that can be automated as a scheduled task.
Any help would be greatly appreciated
Oh, and I'm currently working with a Modicon M340, but there are some quantums and I can't remember what other devices we'd like to have this functionality on.
