Hi Expert house, We are using for valve feedback time out defined in UDTs. There are two time settings TD0 and TD1. We have at least 50-60 valves of various types like Diverter valve, flap valve etc.. with separate UDTs My question is if I wish to change the time in UDT. What is the procedure. 1) Go ONLINE with PLC and change in UDT 2) Then shall open individual valve blocks where this UDT is used. In fact each valve block has called block FC117 where this times are used.. So is it OK if just I open FC117 and save it. OR any download of FC117 is envisaged. Next question is that if by any reason I want to affect these time changes in only one valve block but not all, is there a way. If valve feed back error bit is forced (it is "M" type in logic) will it avoid trip Thanks in advance Vijay Attachmentdiverter valve_pic2_PNG.pdf (67 Downloads) |
