Hi All, this forum has been of a great help for me in learning.
i have two problems
1- I have setup an alarm so i want to calculate the number of times the alarm goes on for that i can use a counter but in counter i have to set a specified value upto which it can count so what is a better approach
2- below I have attached a pic of my output window i am using two ML 1400. Input is given at plc1 and output is at plc2. They are connected via ethernet switch now when i unplug the cable of plc1 the output goes off with error bit being enabled on message command but when I plug the cable in again the error bit stays on and i have to go offline and then online again to turn output on. what is the solution to that when i plug the cable in again the program starts working again.
thank you
