If the program in the PLC was created using Logicmaster or VersaPro, you should still be able to upload from the PLC to PME. Be aware that you will not be able to get variable descriptions or rung comments. Those are not included in the runtime file on any 90-30 PLC.

The serial port for communication with that PLC is the fifteen pin port on the power supply module. The port itself is RS485, so you will likely need a RS485/RS232 converter. This guy has a good selection of cable options, decent experience with connecting GE Fanuc 90-30 PLCs, and a good reputation for customer support. I'm pretty sure he ships worldwide. www.PLCCable.com

Posting the same question in multiple threads is unlikely to generate more or faster responses. Its more likely to generate confusion if some respondents post in one thread and others in a different thread.

I have uploaded LM90 version 9.05 to my Google drive. Send me a private message with your email address and I'll add you to the share list. Do you need instructions on how to restore from your backup files?

You did not answer my primary question. Why do you think you need Logicmaster rather than something more current?

People frequently ask me to send them Logicmaster software and my initial response is always the same: Why do you think you need it? Logicmaster is a DOS application that has been obsolete for more than a quarter century. There have been three different programming software packages from GE/GE Fanuc/Emerson since it then, and if the program in your PLC was written using any of them, Logicmaster won't be able to touch it. You will need to run Logicmaster under a 32-bit operating system if you need to upload or download since Logicmaster's serial communications driver isn't compatible wit a 64-bit OS. If your program was created using Logicmaster, the current software from Emerson called PAC Machine Edition will almost always be able to import the Logicmaster file or upload it from the PLC. Bottom line, convince me that you really need Logicmaster and I'll be happy to share it with you. But you'll quite likely find that the current software is easier to use.

To use the SRTP protocol on the ETM001 you will need to add logic to set it up. It's covered in chapter 8 of GFK-2224. https://emerson-mas.my.site.com/communities/servlet/fileField?retURL=%2Fcommunities%2Fapex%2FKnowledgeDetail%3Fid%3DkA31t0000004ZgBCAU%26lang%3Den_US%26Type%3DDocumentation__kav&entityId=ka3QA000000fTNpYAM&field=File_2__Body__s

View Lock means that program block can not even be viewed, never mind edited. If you can't get the password from either the end user or the people who originally created the program, you are out of luck. There is no 'backdoor' password.

Most likely it will have to be one of the versions since Emerson took over. I think the last GE version was around 9.8, so probably something in the 10.x range.

If the default passwords don't work, all I can suggest is to try to contact whoever applied them or restore the device to its factory default state. This isn't a forum for discussion of password hacks.

Whenever I'm troubleshooting faults denoted by bits in a word I look for a place in the program where all faults are cleared by moving a value of zero into the word.

It might be easier to set up an array of long integers and use the value from the HMI as the index.

First, regarding your concerns about losing the program. There is a capacitor on the CPU module that will maintain the RAM memory for a few minutes if the CPU module is removed from the baseplate. There is also a connection point to attach a battery directly to the CPU module. The connector is located behind the front cover near the top. You need to remove the cover to see it. Regarding communications, your XP virtual machine must be a 32-bit version of XP. The serial communications driver in LM90 won't work on a 64-bit OS. The diagram you posted is a 'cheater' cable for a passive conversion from RS485 (the port on the power supply) to RS23 (the PC serial port). It might work, but no guarantee. The Horner device is a RS232/RS485 converter. It gets its power from the port on the power supply. The download of the program and the hardware configuration is to the port on the power supply in the rack with the CPU module. The power supply in the expansion rack is the same as the one in the CPU rack, but the power supply port is non-functional in an expansion rack.

As Victor Lazlo said to Rick Blaine in Casablanca, "Welcome back to the fight Chris. Now I know our side will win."

In GE's part numbering scheme, characters following the dash are just version numbers, denoting either a hardware or firmware modification. The two models you cited, -HK and -GF, are both newer than -AB, so they should be compatible with whatever is in your runtime project in the -AB.

If the link doesn't work out, send me a PM with your email. I've uploaded LM90 to my google drive and I'll add you to the share list.

I'm assuming this is a system that formerly worked properly and has suddenly started giving problems. You have already checked out the expansion cable and the termination resistor. Next, I would check the power supply in the expansion rack. As power supplies age, their capacity declines. The one in the expansion rack may have been sufficient to power the population of modules when it was new, but now it could be insufficient. If you have a spare, try installing it. Or else swap the power supply in the CPU rack and the one in the expansion rack. If the cables and the power supply aren't the problem,the next step would be to replace the baseplate.

Did Logicmaster configuration indicate "Config EQ" when you were online with the PLC? Is the termination resistor installed on the cable at the expansion rack? Have you verified expansion cable integrity?

If I had to install one immediately, I would go with VFD #2. After twelve years on the shelf, the bus capacitors in VFD #1 may need reforming. I would also check the manufacturer's recommendation to see how long the capacitors can go without reforming and go through the process if necessary to make sure you have a viable spare.

The expanded I/O addressing is mapped to R memory as shown on the third page of the pdf. It was a way to use register (16-bit) memory for discrete instructions since the Series Six instruction set did not permit anything like R123.00 to indicate the least significant bit of word R123. In programs that use the feature, you had to be careful not to use the R addresses corresponding to the expanded I/O addresses for timers or arithmetic operations. For your specific example, I1+0000 through I1+1023 are mapped to R193 - R256 with I1+0193 through I1+0208 mapped into R205. Thus, I1+0193 is bit zero of R205, I1+0194 is bit 01, etc. When converting to Rx3i, just use discrete memory or boolean symbolic variables. Whenever I've done Series Six conversions I've always referenced the Series Six address in the description of the Rx3i variable, along the lines of "was I1+0201". It helps in proofreading and debugging. You should also check the Series Six program to see if the corresponding R addresses are used anywhere.

I guess the question that needs to be asked is why is it necessary that both monitors display the same screen when an operator at either screen could easily navigate to any screen?

I have never set up a system like this myself. The help files seem more geared toward multiple View Runtime targets on computers rather than multiple Quick Panels. However, there does seem to be a distinction made between clients and servers with the implication that one HMI needs to be a server and the other a client. On the client, it appears you need to set up a directory for the data shared over the network. The following is from Proficy version 9.5 help. On the Client computer, create a folder where logging, alarming, and networking files will be stored. Share the folder as 'FrameworX'. See your Operating System guide for information on how to share folders. Have you set up a directory on one of the Quick Panels and is it shared?

I don't know if it will help in your situation, but I found this discussion on the Emerson forum. https://emersonexchange365.com/products/control-safety-systems/f/plc-pac-systems-industrial-computing-forum/10614/temporary-ip-settings-for-etm001-module-in-me10-0
