Safety M580 offline configuration in OFS

Domenico

Hello guys, I successfully configured a connection from Citect to a M580 Safety PLC by using the OFS. I imported the *.xvm file in the OFS and while the PLC is on line everything seems to work. The question now is: how I can manage citect configuration update  (eg. tag addition, deletion,...) if the PLC is not phisically available? The M580 soon or late will be shipped on final site so it will not longer available in my lab, so I wonder how I can modify the citect tag database if  the M580 is not phisically in my hands. I know that it is possible to load the PLC application to the Control Expert simulator, but this means that I need an instance of such software installed on the SCADA development station so, at the end, it is possible to develop a citect application WITHOUT the M580 PLC and WITHOUT the Control Expert software?

In addition, since the M580 configuration I developed is a safety application, it has 2 application programs inside: 1 for the standard PROCESS and 1 for the SAFE copro; this means that I have two *.xvm files (standard+safe) while in the OFS configuration I can load 1 file for each alias. There is a way to merge the process and safe xvm in one single file? If not I need to configure 2 alias for each safety M580 in order to load two separated xvm files or it is possible to "force" two xvm in one alias?

Thank you

  • Hi Patrick and thank you for your help!

    Knowing that the simulator is portable among different PC is very handy and give a big help during the development and test phase; thanks to your suggestion I just tested it on 3 sistems without any perticoular problems.

    I better investigated the xvm file usage in the OFS and essentially I can use it in off line mode just clearing the "Using Data Dictionary" option in the Alias configuration:

    By selecting "Using Data Dictionary" option the OFS reads the tag configuration directly from the PLC instead, so we need the phisical CPU (or simulator) in order to complete the citect configuration.

    In addition I discovered that a complete xvm file both with the process and safe tags is automatically created by the Control Expert once the software is compiled and downloaded to the PLC. You have to tick the option "save XVM" in the project settings:

    the auto created xvm file is saved in the directory C:\Users\Public\Documents\Schneider Electric\Control Expert 14.1\  (depending on the Control Expert version)

    At last, I can confirm you that even the SAFE application runs on the simulator.

    Thank you again for your help.
