Hello everyone, I recently acquired an older Pemas injection molding press equipped with a Sigmatek control system featuring a CP 626 controller. Unfortunately, the company from Austria that manufactured it seems to have gone out of business, making it difficult to find support. Upon powering up the machine, an error message appears stating: "SIGMATEK ROM-DOS V 1.1 RAM DOS ERROR. INSERT SYSTEM DISK AND HIT ANY KEY FOR RETRY." There is a floppy disk port located next to the machine's screen. Despite trying to insert a floppy with DOS 1.1, the machine remains stuck on "SIGMATEK ROM-DOS V 1.1 LOADING BOOT RECORD." Additionally, I noticed that the machine was missing a memory module on the front of the PLC. I purchased a memory module (MEE 32) from eBay, but it did not resolve the issue. It is unclear what is stored on the MEE 32 since it came from another machine. I would greatly appreciate any guidance on the next steps to take. Should I attempt to connect to the PLC through the CAN bus port? Does anyone have the necessary software to facilitate this process? Your assistance is invaluable, Diego

Hi Diego, this seems like quite a conundrum. The error you're experiencing suggests there might be a problem with the system booting from the ROM-DOS floppy disk. If you've already tried a different DOS 1.1 floppy disk with no luck, it could be an issue with your floppy drive, which unfortunately are notorious for being unreliable after a long period of time. On the other hand, considering the PLC is missing a memory module, it's possible that it needs specific data or a specific configuration on the MEE 32 that you don't have. An incorrect configuration could prevent the system from booting. Connecting to the PLC through CAN bus could be a good next step. But since Sigmatek is out of business, finding the software needed to communicate with the PLC could be a challenge. You might want to reach out to other machinery companies or PLC specialists who may have the capability to decipher the communication protocols used by Sigmatek. Good luck!
Hi Diego, it indeed seems like a challenging issue you've got on your hands. As your MEE 32 memory module was sourced from eBay without explicit knowledge of its contents, I would suggest starting there. It might be that it contains an incompatible or corrupted version of the system software. If you have access to a correct and verified copy, you could try to format and reprogram the module. Alternatively, you can reach out to other professionals who might have a similar machine and procure a module from that source. As for your CAN bus question, attempting to connect through the port could provide valuable information if you have a CAN monitor. However, please be aware of the possibility to inadvertently cause more harm if not done correctly. So, proceed with caution and consult with an expert if you're uncertain. It's a good idea to exhaust all your options but the solution might be something simpler. Always remember, sometimes, it's not about the most complex solution but the right one. Good luck!
Hi Diego, Sounds like quite a situation you've got there. Firstly, from what you've said, the error message hints at a DOS system that can't boot up due to a possible RAM error. Generally, this could mean that there's a faulty memory chip, but since replacing the MEE 32 memory module didn't solve the problem, it may be something more complex. Secondly, regarding the software, since Sigmatek is no longer in business, it might be challenging to find the exact software you need. However, I'd suggest looking for third-party professionals or companies that restore older machines. They may have the necessary software or know where to find it. As for connecting through the CAN Bus port, that might help you diagnose the problem, but you'd need the correct software for communication and a PC interface card for CAN bus. Also, remember to check if your replacement memory module is compatible and properly inserted. Maybe your machine requires a specific boot disk or memory module. Good luck on the troubleshooting journey!

Answer: Answer: To resolve this error, you need to insert a system disk and hit any key for retry. Ensure that you have the correct system disk containing DOS 1.1 and try inserting it into the floppy disk port.
Answer: Answer: If the machine remains stuck at this stage, it could indicate a more complex issue with the boot process. You may need to explore further troubleshooting steps or seek assistance from a specialist.
Answer: Answer: Yes, missing memory modules can affect the operation of the controller. Ensure that all necessary memory modules, such as the MEE 32, are properly installed and compatible with the system.
Answer: Answer: Connecting to the PLC through the CAN bus port can be a potential troubleshooting step. However, ensure you have the necessary software and expertise to carry out this process effectively.
