  1. Several years ago before I arrived at my company, an integrator came in to do the automation on our system. They used a Controllogix 1756-L61S for the safety portion of the project. Apparently, when they completed the job they did not provide the source code with comments, safety password, etc. for anything and it got ugly between our company and theirs. In other words, they would not provide it if we went back to ask them. Allen Bradley has told us that we can not make any alterations now to the safety logic because we do not have the password that was used to create it. And they said there is no longer a master password that you could use like in previous controllers. Does anybody know of any workarounds for this? Or have heard of anything that might possibly work?
  2. I am using TIA portal to make HMI screens for a KTP700 BASIC HMI panel. I am using the built-in password protection pop-up screen. Is it possible to change the font size of text items on the password protection screen? The text, and the user and password fields are a bit small. I would like to make them bigger. Thanks in advance.
  3. NT2S Display - LOOP

    Hello. I have switched from NT2-ST software to NTXS. Now I'm having one small problem. In old software (NT2-ST) I had special screen called LOOP. You defined screens in this LOOP and the display would stay in this loop (using buttons NEXT/PREV) In newer software (NTXS) I can't find anything similar. Do I have to make LOOPS inside PLC to modify STR register? Or define a BUTTON Function on EVERY SCREEN? This would make a nightmare. Thanks. Best regards.
  4. Hello, Can a password protected PLC be updated with a help a memory cassette? The documentation states that it is not possible. But if the memory cassette is protected with the same keyword? Thank you.

  7. Panasonic FP-X C30R

    I'm very much a novice to plc programming. I've dabbled in years past with Mitsubishi FX units with Medoc long before G X Developer became available. I also did a bit on Schneider using Zelio software. All very much simple stuff using ladder logic and internal relays But I've got me a Panasonic PLC that is surplus to requirements where I work and I would like to investigate the possibility of using it for practice purposes. Who knows, I might even get it to do something useful. I expect it is a few years old - its got a version No 2.4 and what seems like a date on it 080916. First query - is there software available for this item. Second query will it be compatible with a computer running on Windows 7. I've checked on the internet and see that there is documentation out there the plc. I decided ask for some informed opinion from before I go too far into what turns out to be a "cul de sac". Regards jaymac.
