Note: This will probably be another of my long rambles. As most know I am not a "programmer" even though I deal with plc's consistently.
We have a rewinder that is approximately 12 years old using a Klockner-Moeller PS316 plc. The ANALOG cards are not available for this device anymore...IF YOU HAVE ANY LET ME KNOW IF WE CAN OBTAIN THEM, PLEASE.
What has happened is one of the Analog cards has failed, the module is good but the card is bad. We have called in a tech from the company that originally designed the control system, we have "rigged" an alternative to the analog cards. NOTE: I do not like this alternative (I could have done this but didnt think prudent nor liked the idea but y'all know engineers and management).
THis system is unique in that because of the drives (Amicon, which is now GE labeled drives) it needs 2 computers to interface FIX (intellution) and the plc/interface.
OVERVIEW
Rewinder for 30" to 40 " wide paper.
Has 2 spindles/shafts to wind paper on that turret (rotate) then match speed for auto splice sequence, existing drives are AMICON
Uses 2 75HP DC drives for the spindles
Turret motor is smaller and fixed speed...maybe 10HP AC (will have to verify).
PLC is Klockner-Moeller PS316 with 3 16 point Digital Input cards, 2 digital output 16 point, 1 4 channel analog input, 2 4 channel output cards and 1 HSC that I think is dual channel
Interface is Intellution FIX which has to connect to another computer to communicate with the drives.
MY QUESTION is thricefold:
First because this PLC has obsolete parts it is my major concern I need to replace it...I have in stock MANY GE FANUC 90-30 with all the parts needed but the analog cards. NOTE: I would prefer AB and you may understand part of that with the next statement but it may not matter.
Next are the drives, they are older etc and I have 2 Reliance Flexpack 3000 drives in a rewinder cabinet (from a dismantled system) that I would prefer to use...ie the reason for using an AB plc.
I would like to eliminate the computers and use an HMI as the interface because the data that has to be changed is primarily the analog values and if I can interface the GE Fanuc (or an AB plc) directly with the DC Drives I shouldnt have the need.
Questions
1. Does the above seem viable with todays technology to incorporate..ie will the GE Fanuc work or should I go for using an AB PLC?
2. I am not a fool, this is more than I can do in one sitting...ie setup drive and program plc/interface...can I reasonably expect to keep the cost under $15000 US (hopefully $10000 US) even if I have to hire an integrator/programmmer(preferably a programmer that can work with us). NOTE: We have the crew to do the preliminary install/wiring (mainly me) but a crew of hard wire electricians. Technically a programmer is all I think I need, the rest we can easily do.
3. TIME...as usual is of the essence. Is it viable to expect to do this within 3 days of actual downtime (I understand the work may take longer doing the install/wiring/programming).
I know I tend to ramble on but this is a real problem that I have now...the alternative they have come up with is to go get an OLD OLD rewind from a closed factory ...personally I dont think that option is better/cheaper/uses less time than doing an upgrade PLUS it means I MUST deal with more OLD ****. Getting the OLD unit requires sending a crew to disconnect it then ship it, then set it, and reconnect it. Geezus I am OLD and have to deal with myself every day...I get tired of dealing with OLD.
Last but not least...I MUST have FULL access to all programming.
Thanks for listening/reading...all thoughts will be appreciated.
