Thank you steve

Steve, Russ... will the plc (cpu rack) talk to the workmaster even i dont connect it with an i/o rack? thank you...

Hello, yup guys i know , i work at a company that has a very bad procurement dept and overall management, i requested from them on 2012 to obtain the three main modules on the cpu rack and the power supply as a ready spare, on 2014 i made a followup request for the arithmetic and logic module, when ever i followup on them they just say that they are having trouble looking for these modules, but really i know for sure that there are quite a few of these parts on online, The techs suffer from horrible bosses and bad management

Thanks steve, our plc has failed, maybe bec of old age... http://forums.mrplc.com/index.php?showtopic=29518 any help from you guys is greatly apreciated thank you...

Hello, back on 2012 i posted on this forum about the weird behavior of our series 6 plc... http://forums.mrplc.com/index.php?showtopic=24079 And now the plc has finaly failed, it started when 1 output was not responding so we decided to reset the plc thru the cpu key switch and it did not run again, theres also no cummunications between the workmaster programer and the plc, the manual says try reseating arithmetic module, logic module & i/o module, still it failed to run, we pulled out the cpu rack and on our workshop after many power cycle reset this happened once... https://youtu.be/mInx-7s2RIw The biggest drawback is we have NO spare modules I would like to ask you guys if anybody has experienced this, and any suggestions what module to check first for an attempt of board repair... Thank You..

Thanks Russ, i have the GEK-96602A manual but there's no instance of backplane power rails there... We have only one PLC unit and cant afford the downtime just to trace and take notes of the power rails, I guess il just have to wait for it to fail hehehe....

Hello GE experts, need help on module supply voltage pins, i have some Input modules lying around and i want to power them up off the rack (on bench), thanks...

Hello Mr. Steve, im having dificulty copying the ladder wich is loaded on the PLC bec it is saved on a 1mb floppy disk wich cannot be read on a desktop floppy drive, it can only be read on the workmaster floppy drive, any way im going out for my 30 day vacation, we will pick this up after i get back ok Mr. Steve? Thanks again for your effort.

Hello Mr. Steve, i may have posted a wrong ladder, il try to get the one that is loaded on the PLC. Thank You for your effort.

Hello Mr. Steve, i have attached the ladder for the ALS, thanks. KFIA_ALS.rar

Thank you Mr. Steve, ill post the ladder as soon as i can.

Hi, I hope someone can help me with my Problem regarding Series 6 PLC which is programed to control "ALS" or Airfield Lighting System in an airport which i work at, the ALS has timer dependent lights which is programed to automaticaly turn on after 60 seconds whenever the operator or user switches it off, the problem is that the lights turns on in less than 60 seconds usualy 20+ secs, i have checked the ladder and all the values are correct and i am using as built and un-edited ladder, Timer is set to TS or to count in seconds and it is set to count 60 seconds. what i have noticed how ever is when i monitored the timer on the workmaster computer is that the counter is counting faster than it should be thats why even i have have the correct value for the timer which is 60 secs for the timer dependent lights it still turns on within 20+ secs. Could it be a hardware problem? Could a bad power supply cause Clock or timing problem? These are the module boards on the PLC IC600CB500K ARITHMETIC CONTROL MODULE IC600CB502L ADV.
