I have a friend of mine that just called me from CA. All the lights on the SLC 5/04 are flashing around like the CPU is in infinite reset. They are out in field and dont have the laptop with them When they put the processor in PROGRAM it stops cycling the lights and appears to act ok, Once he puts it back in RUN mode, ALL the lights are flashing Any ideas? Thanks

Hello All, This is a post for a friend of mine. He is using RsLogix 5000. When uploads a file from the processor, it uploads the program, but doesn't upload the Tag Names, Rung comments etc. Its just the actual lines of logic. He also says he isn't getting the prompt for the uploading of Data Tables. Any ideas? Thanks for the help

Hello all, We have an old PLC driven steam generator. PLC is a Allen Bradley SLC 5/04 with a Allen Bradley DTAM Operatar Interface that is connected from the RS232 port on the SLC to the OIT. Yesterday I attempted to hook up my laptop using a PCMK card, and RSLinx didnt see it the processor. PCMK card is good, and RSLinx configured properly. What could it be? any ideas? Thanks John Bourg

PCMK was connected to the DH+ or DH 485 port. DTAM is connected to the RS232 port The PCMK is configured under "configured drivers" in Rslinx.. but the Network setup for the PCMK card is currently set up for "DH+". I wonder if i have the option to set to DH485? In fact I did notice that the DH+ LED on the SLC was just flickering on/off..not solid like I'm used to seeing on other processors. Could it be something in the communication setup in the RSlogix 500 controller properties I used the PCMK Card / cable on another PLC just before I hooked up to this one so I know (well think) that that part is ok

When you use the "Compare" function to compare to different RsLogix files, can you export that to .pdf or similar? I need to run the Compare tool, and be able to email the report. Thanks for the help

Thanks Bob, Logix compare report sent via, .pdf Thanks again

We had a similair issue, the problem was that oil yes oil, had leaked from the old conduit onto the chassis (backplane) causing the same problem. It wasnt till I visibly saw oil on the back part of one of analog input cards that I found the problem. You could also make sure its not looking for a EEprom to load from on Boot that isnt there: Data File S2 under Memory Module Tab: Memory Module Loaded on Boot S:5/8

I have a friend in CA that is trying to hook up directly to a Panel View 1000 (2711-K10C8L1) RsLinx lite configured for DF1-Rs232. Panelbulder 32 version 3.8 He was able upload/download to his SLC using a 1747-CP3 using DF-1. I did some research on the 1747-CP3 cable, and a old thread said that this cable will not work when hooked up directly to a Panelview. He got a serial cable to hookup to the panelview 1000 I'm here in Maryland trying to troubleshoot his communication issues so bare with me. I asked him first if there were 2 RS232 ports on the Panelview 1000 (one for printer, other for communcation) he says no that there is only one. I had him verify Rslinx DF-1 config. when he hits "auto configure" , Rslinx just wonders, and doesnt see the panelview. I ask him to open Panelbuiler 32, and at the open/new/upload/download box I had him select "Upload" He gets a box with "ok" and a little "caution symbol" This is 101 in PLC's, and its killing us because we both know it, but are exhausted out of ideas

An update. Turns out he bought a null modem calbe instead of a serial cable I'll let the forum know how things went once hw gets the proper cable

A friend of mine is trying to comunicate with a SLC 5/04. He is using a PCMK card. Series B He has installed the PCMK Driver correctly. He has set up the correct driver configuration for the PCMK in RsLinx correctly (Rslinx-lite) Once he hooks up to the SLC, Rslinx only sees his workstation. He verifiied the cable from the PCMK to the SLC, even purchased a new one. The question is that the RSlogix 500 , file under "channel configuration" Channel one is set up for "DH+", with a baud rate of 230k Could this baud rate be set to high? Since this is the current file installed on the SLC that is functioning properly, could the fact that the baud rate in the Rslogix file be causing issues with Rslinx seeing the processor. The only other thing I supposed is a faulty PCMK Card. Thanks

Thats the exact cable he just bought. Thanks

We have the workstation node set to 77. Its got to be the PCMK card. In Rslinx everything is "RUNNING" no errors.

Will do Thanks

anyone ever experience this fault 684 on there panelview. Simply cycling the power on the Panelview gets rid of it, but kinda curious as to what this is. Any thoughts

Well the demon came back, and I suggested checking the power supply, and indeed it was the power supply. The power drop was enough to cause the SLC to go into infinite cycling of start-up reset. They replaced the power supply, problem solved mracer called it first

The decision was made to replace the SLC 5/04 because of its age. They downloaded the RSLogix file, and everything appears to be ok.

Thanks Ken, It appears that It's repeating the start up sequence over and over. I suggested cycling power. verifiy the battery Do a upload and go online to verify any possible errors, but usually in my experience you will get a FAULT on the CPU if thats the case. I think they are going to try to wipe the processor (VBB /GRD) and try to re-download. If that doesnt work then it's more than likely the SLC is faulty. The processor is quite old, so maybe its time. I'll post what they find I'm presently in Maryland tryin to help a California bud Thanks again Ken

I have a question about the Analog Output Module 1746-NO41. For a 4-20mA output the scaling is 6242 for 4mA, and 31208 for 20mA per the manual. I have discovered that the program on one of our systems has the scaling wrong per the manual, 6242 for 4mA, and 32208 for 20mA. I'm going to change it to what the manual states 31208 for 20mA. I have been having some infrequent issues with the outputs on this system. What effect would this incorrect scaling have on the analog output card itself. In other words if the SLC is calling for 20mA output and the scaling is off, what would this likely cause. Sorry if this is a dumb question. Thanks, John B.

I have a question. If you have a SLC 5/04 that has an EEPROM. Does the processor pull from the EEPROM everytime you lose power or only when the battery is failed. Isnt the battery supposed to hold the current program if you lose power, and only load from the EEPROM if the battery fails?

Is this the correct part # for a SLC 5/04 and 5/05 Memory Module? Part # 1747-M13

Well I just finished up a major project upgrade for one of our critical systems, and it went flawlessly. I had to do quite a bit of RsLogix, and Panelbuiler programming myself. I want to thank first the owners of this site because of the wealth of knowledge on this froum is tremendous, and has helped my PLC/Programming skills a huge amount in a short time. I also want to thank others like TWControls, and others like Ken Roach who have answered my threads quick enough so that I dont go home staring at the ceiling all night scratching my head. Now I'm am no way an expert, but I have the ambition to be the best I can be at this. I was givin alot of praise here at work for my efforts, but I feel I need to share it with you guys. Thanks, John Bourg

The company which I'm currently employed with is finally getting a couple of newer laptops They want me to get some quotes on purchasing RSLogix 500 Pro for these 2 laptops. What is the expected cost? Do I have to buy it twice or do I get a break on the second activation. Should I goto Rockwell directly? I think our so called "Preferred Vendors" are gouging us on this Thanks for the input John B.

Thanks Ken That helps, I'll order it tomorrow

Well money isnt really tight, this is a billion dollar company I work for, but if I can save them a few bucks I will. If not then I'll just order it. Just thought there quote was a little high. Thanks fellas

I uploaded this PanelBuilder file from a old PV 550. I cannot open it up. Can anyone else try it to see if they can, and maybe have some input as what to do? Thanks baxter_w.PVA
