Comissioning of Redundant 900F with S800IOs
i want to know the steps for comissioning the DCS panel IP55 in which i have Redundant Freelance Controllers 900f with S800 IOs on Profibus and Modbus Devices to communicate probably RS 485,ABB Drives on Profibus i have one Engineering Station and Two Operator station
Writing down steps here will be duplicating information from manuals, I recommend to check above topics in online help or in following manuals.
Redundant AC 900F go through 2PAA109295 M&I - AC 900F Controller.pdf
Commissioning of AC 900F go through 2PAA109293 Engineering - Process Station - AC 900F.pdf
S800 I/O if you are using via GSD then check S800 templates app associated here with
Modbus communication check manual the M&I and 3BDD012515 Engineering - Communication and Fieldbusses.pdf
Also check associated app for drive integration please note that engineering is same as AC 800F.
This is a rather broad question. If you never did a Freelance project before have a look at the "Introduction - Getting Started" manual. See section 3, First Steps.
Remember to download "bottom up". That means start with the download of the Process Stations, which will also download the PROFIBUS configuration to the S800 and Start the Modbus communication. The Operator Stations should be downloaded after the Process Stations.
If you already did Freelance projects and know in principle how to commission a project, then I propose you be a little more specific with the problem you face.
