Siemens graphical trending

[sparkotronic]

Hi all, I'm now finding myself being thrust into the world of Siemens Step 7 after 3 years on a Bradley exclusive site. I'm looking for some software to mimic Bradleys trend function on Step 7. I was using a 3rd party OPC trender for the Bradley PLC's and I'd like to continue using this. So....my question is, Can I access S7 PLC's via OPC? If so, what do I need software why and free if possible :) Cheers, Colin

As far I can see, there is no free software for OPC comms with Siemens plc. Siemens opc software is S7-Lean but you can use KepServer as well.
