Peak analog

[mhollida 0]

Hello all need some help with a project. Am using a 1200 with IF2OF2 analog card. One channel of analog input reads a pressure transducer for machine hydraulic pressure. I already have it set up and scaled to read pressure on a display (Proface operator panel). WHAT I need to do is capture the peak reading during a segment of the machine cycle. I have bits that define the start and end of the measuring period. Any ideas on this. Thanks for your help Mark

Do a compare of the analogue and an integer, if the analogue is GRT than the integer and it is the sample period then MOV analogue to integer. SOR XIC B3:0/0 GRT N7:0 N7:1 MOV N7:0 N7:1 EOR B3:0/0 is the sample period bit N7:0 is the analogue N7:1 is the integer that strores the max PS you can copy paste the line above into RSlogix by selecting to the left of the ladder (goes red) then pasting.
