wimzwart Posted November 11, 2013 Report Share Posted November 11, 2013 Hi, I'm looking for some help with the following: My client is looking for a alarm in a existing program in U90 ladder. He wants to have a alarm when a curtain input has been active for example 5 times within a curtain time for example 24 hours. So I need a combination with a timer and counter to set a output alarm. For the amount of times I want to use a Variable to let the operator change it. Can somebody advise me how to solve this or has a example for this. Thanks Wim Zwart Quote Link to comment Share on other sites More sharing options...
