Dear Sir, I am facing a strange problem....I am having a multiproject with 3 PLC's connected by MPI network....HMI is WinCC....I am attachingPLC project also... The problem: In OB1, network-35 of PLC-1&2...it calls FC80(a protected block) with many timers defined as "IN" timer datatype...I am not able to find out where are these timers (Ex.T14,T15,T37,T47, etc.,)....using Location I am seeing as read....I want to know where these timers get initiated? The MPI is using a global data table....But strangely in the table I cannot find the timers... I find timers only in main PLC-3....My questionbecomes... Are these timers being used at PLC -1&2??.....Also by using variable table both at PLC1&2 I observe different timing...I also saw HMI whether these timers are created by them...But I am new to HMI so couldn't come to any conclusion. I donot want to confuse you.....Please look at the project along with HMI and help me to understand where the timers get initiated? AttachmentPLC_project.zip (423 Downloads) |
