Dear all member,

          Hello every one I have two problem as follow:-

I am working on S7-300 with siwarex M but now I want to replace Siwarex M due to some issue. When I called to quotation for same peoples are telling that this model of Siwarex is outdated So I want to know which module I should use in place of Siwarex M.

        And same time will same PLC ladder logic will work with new one weigh module or we have to change it ?

         As on other PLC I was working S7-3-- 314c-2DP with Siwarex FTA  so there is some issue in feeding system be weight. So when I checked ladder logic what I fount all inputs of weight coming fro a Protected block called Siwa_FTA and It's showing protected so How can we open that block & how can I program a Weigh module ???

 Please help me in this problem ..!
