You will need to indicate which model PLC you have before you can get any meaningful assistance. If you contact a local distributor of GE Fanuc products, they might be willing to make the programming software available to you. If the PLC belongs to your school, then the school should have the proper software. -
Bill, There are some quirks with the S90 Micros when it comes to getting to the 'Logic Equal' state. It may have to do with the use of the 'Always_On' bit (%S0007) or one of the other internal system bits. I can't remember the details, but I think there used to be something about it among the FAQs at the GE Fanuc website. Try this link: http://elitenet.geindustrial.com/techadvis...,Case=obj(2820) -
I keep an old DOS computer on hand for running LM6, so I can't offer any first-hand advice. The newest Windows version I've run LM6 (serial version) on is Win95. The challenge will be to get Win 98 to recognize the parallel WSI board. I expect your config.sys settings would be the same as they would be under DOS. -
Go ahead, ask for a raise. State your case as you've presented it here. Your efforts are making X dollars per hour for the company, and you think you should get a piece of it. Presented that way, the worst the boss is likely to do is turn you down. You can buttress your case even further by checking to see what a person with your skill set might be earning at another company. Just don't make it an ultimatum, as in "If I don't get a raise, I'm outta here". Presented like that, your boss is likely to call your bluff. -
These two units have been "blessed" by GE Fanuc product support: HE500USB600A from Horner Electric http://www.heapg.com It has been tested with Logicmaster, VersaPro and CME. Belkin model F5U103. It works with VersaPro and CME, but not with Logicmaster. -
power up mode
in GE
Check the fault tables. If it's configured to power up in run mode and it won't, the reason is probably that there is a fatal fault preventing it from running. Once you correct what caused the fault and clear the fault tables, you should be good to go. -
PROGRAMMING
in GE
If you're already familiar with some other brand of PLC, and you're comfortable working in DOS, picking up the quirks of Logicmaster won't be too difficult. If this is your first-ever PLC project, your learning curve will be longer. Since you already have the PLC and software, you might be interested in programming some simulated processes to learn basic PLC applications. The advantage to a simulated process is that it runs entirely on your computer. If your program doesn't work the way you expect, you don't break anything. Check it out at the MRPLC store. http://shop.mrplc.com/view_product.php?product=PS32001 -
PROGRAMMING

Logicmaster is GE Fanuc's generic name for its old DOS-based programming software. There is Logicmastyer One for the Series One, Logicmaster Six for the Series Six, Logicmaster 90-30 for the Series 90-30, Logic master Five, Logicmaster 90-70, and even Logicmaster Three. The current programming software is called Proficy Machine Edition Logic Developer PLC. If you're just getting into GE Fanuc PLCs, that would be a better place to start. If you're trying to learn enough to be able to support existing PLCs that were programmed with one of the Logicmaster packages, you need to specify which one. Having said all that, I'm not aware of any books or tutorials specificaly targeted to any of the Logicmaster packages, although the manuals for all (except Series Three) are available. -
Something like this perhaps? http://shop.mrplc.com/view_product.php?product=PS32201 -
NO. The PLC PWM output is a low-voltage DC signal. A 3-phase AC motor requires an AC signal. The rated current of the PLC output at 24 VDC is 0.75 amp. The speed of a 3-phase AC is a function of the frequency of the applied voltage. Even if you argue that the PWM waveform looks like an AC waveform, the PWM output does nothing about frequency. How were you planning to wire this up? A 3-phase AC motor needs three wires to it. There is only one solid-state output on your PLC (IC200UDR005). Do you need any more reasons? You might be able to do crude motion control with a PWM output fed to a VFD's analog speed reference input. Make sure the RMS voltage from the PWM output doesn't exceed the maximum value that the VFD can accept. The basic strategy would be to have the PLC create a trajectory, and assuming that the motor follows the reference. The area under the plot of velocity vs time is the distance traveled. Without feedback, the emphasis is on the word crude. Your accuracy and repeatability will be lousy. -
If I understand your question correctly, you want to know whether it is possible to control position using an AC motor and drive without any position feedback device. The answer is yes as long as you're not particularly concerned with accuracy, repeatability or speed of response and as long as you've reached the target position you don't need much torque to maintain it. -
90-30 PLC copy
in GE
The only way I know of is to get the password. You can try contacting the original manufacturer of the machine or the original programmer. If you're forced to guess, there are 65536 possibilities. The password is a 4-digit hex value between 0000 and ffff. A lot of manufacturers that use passwords tend to use the same password for every machine so the field service people will be able to remember them. Try variations on the machine's model number or the telephone number of the manufacturer's home office. Try the machine's serial number. Put yourself in the position of the engineer at the machine builder. You need to come up with a password strategy that will prevent unauthorized people from accessing the code, but you need to make it possible for authorized people to get access at any hour of the day or night. How would you approach the task? Of course, it's possible that the password is random and unique to your PLC. In that case, if you can try one number every 5 seconds, it will only take you 91 hours to try out all the combinations. -
I got hung up on the String vs INT aspect of the question. Russ, over at the GE Fanuc forum was sharp enough to identify the real question as being about indexed addressing. I'd have more respect for your criticism, guest, if you would register and identify yourself. Any jacka$$ can take anonymous potshots. I'm not calling you a jacka$$, just pointing out that you're exhibiting behavior that could lead a person to the conclusion that you are. -
I just uploaded the Series One Junior manual to the site. http://forums.mrplc.com/index.php?act=Downl...&CODE=02&id=370 -
File Name: Series One Junior Manual File Submitter: Steve Bailey File Submitted: 8 Feb 2005 File Category: Manuals, Tutorials Hardware and programming manual for the old GE Fanuc Series One Junior. This was a Koyo product that was never marketed by TI after they took over the product line nor by Koyo after they started PLC Direct (later Automation Direct). It uses the s Click here to download this file -
The manual for the Series One Jr. is publication number GEK-90503A. It is not available online, but it is available in pdf format. Contact your local GE Fanuc distributor and ask for a copy of the 'Legacy Products' CD. -
The MOVE instruction copies the bit pattern from the source to the destination. It is up to you to interpret what the bit pattern means. -
QuickPanel
in GE
What Quick Panel model and download cable are you using? The cable HMI-CAB-C49 has a converter that draws its power from the QP port. It's possible that either the converter or the QP port is damaged. -
Timer Problem
in GE
Create a timer that resets itself after one minute. Use the output from that timer as the input to a counter. The counter's accumulated value will be minutes, the timer's accumulated value will be seconds. When the counter's accumulated value gets to 120, two hours have elapsed. -
It's been a while since I did anything with a Quick Panel, but I remember that in order to be able to retrieve a file from a QP, the original creator of the screen file must have downloaded it to the QP in the proper format. It was Total Control's version of OEM protection. They called it "Store Project" if you wanted to be able to upload from the QP later. If you stored only the compiled screen files, you couldn't upload. I don't remember what messages you get if there is no project file available for upload, but this could be what you're seeing. If nobody else posts here, you might want to try asking the same question at the GE Fanuc forum. http://gefanuc.bnsi.net/eforum/index.php -

Ask a specific question and I'll do my best to answer it. Versa Pro is not the most current software for programming GE Fanuc PLCs. The software they are currently promoting is called Proficy Machine Edition. Machine Edition requires significantly more computer resources (RAM, processor speed) than Versa Pro. -
Had a Senior moment there. I think I was confusing this forum with the GE Fanuc forum where you can't attach files to your posts. -
Zip up all the files in the folder and post the zip file in the downloads section. I'll open it and print it as a text file and post that for you to to upload. Alternately, if you're on good terms with your local GE Fanuc distributor, ask for a demo CD of VersaPro software. The CD also has Logicmaster on it. There used to be a demo version of Logicmaster available on the GE Fanuc website. I don't know whether its still available. They have placed a lot of the manuals in an area that requires registration to access. I haven't gotten around to registering yet, so I can't post a URL for you.
