RE: PLC Loose connection dettector don01 (Electrical) 6 May 01 08:50 kamran, I don't know of any software for detecting loose connections at the plc. On the input side you could easily write your own. SET a minimum value timer to detect an input rising ( say use pulse rising realy) If the input is lees than minimum time flag it to check the cct. Have a play with this concept and you'll be able to refine it to filter all sorts of issuesLet us know how you goDon RE: PLC Loose connection dettector jbartos (Electrical) 7 May 01 07:52 Suggestion: It appears that there is an inquiry about a self-diagnostics. This feature is not standard and many self-diagnostic features/software are custom made. They usually must be justified.
