Greetings, I am in the midst of working on an older Allen Bradley PLC, specifically the model 1772-LP3 (PLC-2), and I require assistance with program transfer. It is my understanding that this particular controller utilizes RS-422 and Modbus ASCII communication protocols. Can anyone provide guidance or suggest best practices for executing this transfer efficiently? Any available documentation or firsthand accounts would be immensely valuable. I appreciate any support you can offer. Thank you!
To effectively program a PLC with the DF1 protocol, it is essential to have the necessary software. Conducting a Google search can assist you in finding the appropriate software for your needs. It is important to note that program comments and descriptions are not saved in the PLC itself. If you are able to obtain a printout of the program, it can provide insight into its functionality. However, without this information, deciphering the program can be a challenging and time-consuming task. It has been approximately two decades since I last tackled a project like this, so I now respectfully decline such requests. Best of luck in your programming endeavors!
jstolaruk advised using specific software for this operation, which can be found through a Google search. The PLC system inherently supports the DF1 protocol, necessitating the use of the mentioned software. Unfortunately, program comments and descriptions are not stored within the PLC, making it essential to locate a program printout for insight into its functionality. Otherwise, deciphering the program can be a time-consuming and challenging task. As it has been two decades since engaging in such tasks, jstolaruk now declines these requests. Good luck with your endeavors! Inquiring about the software's name required for this task and confirming if an RS-422 communication cable is suitable, or if a different type of cable is needed, would be greatly appreciated. Thank you for your valuable input!
A quick search on Google brings up numerous results related to PLC-2 programming software for Windows, including options such as PLC2Software.com and A-B PLC-2 Programming Software. Additionally, the cable required for programming the PLC-2 may be unique or specialized.TOPDOC PLC-2, available at SoftPLC eShop, is another popular option.
If you're dealing with Allen-Bradley's outdated control system using their specialized communications protocol over an RS-422 connection, it's crucial to understand that it's not Modbus ASCII. This protocol has been obsolete since the 1980s, making it essential to seek assistance from individuals with the necessary tools and expertise in handling it.
jstolaruk mentioned that a Google search brings up various results related to PLC-2 programming software for Windows. Some of the options include PLC2Software.com and A-B PLC-2 Programming Software. A special cable may be required for this programming. However, I have found a new approach to tackle this issue in the modern age. After encountering old processors and facing the same challenges as many others, I have been exploring solutions to overcome this obstacle. It seems that the main difficulty lies in the lack of necessary computer software and dongles. Ken Roach pointed out that the controller uses Allen-Bradley's proprietary communications protocol over an RS-422 connection and has been obsolete since the 1980s. If you are struggling to navigate this process on your own, it may be beneficial to seek assistance from professionals who have experience working with older PLCs. It is essential to have the right tools, cables, software, and setup to effectively communicate with these outdated controllers. Remember, reaching out to experts in this field can save you time and frustration.
Hello there, I've worked on a PLC-2 before and it can indeed be a bit tricky. Given its age, the first hurdle is usually finding a computer that has an RS-232 port for the 1770-KF2 that you'll need for communication. Once that’s sorted, you can look for a copy of the 6200 programming software. Remember, you'll probably need to use an older operating system like Windows XP to operate this. Transfer can be done through Ladder-Read and then Ladder-Write, just remember to run checks for logic errors. Be patient though, as the process can be quite slow. There's excellent documentation found in the Allen Bradley Knowledgebase that goes into more detail on these steps if you're still unsure. Good luck with your project!
Sure, I'd be happy to help! I once worked on a similar model, and I found the key is to use Allen Bradley's 1784-PKTXD, which is a network interface card specifically designed to support DH+, DH485 and Remote I/O communication, basically all the networks the PLC-2 1772-LP3 utilizes. Also, for software, you probably want to look into Rockwell Automation's RSLogix 5000. You'll need a converter in between because the connection is RS232 to RS422. About the transfer procedure itself, have standby copies of your data, as the process might end up erasing the old one during transfer. It does take some patience and trial-and-error, but once you get it right, it's pretty straightforward. Let me know how it goes!
