  1. @Joe E. thanks for a lot of knowledge shared i appreciate it
  2. @pturmel What a great day already to meet you on that forum Phil :) You are a beacon of knowledge on ignition forum so really happy to see your reply. It might be too late as i already fell in love with this over 35 years old PLC :) which i bought for cheap on ebay full of cards. I understand it might be harder learning path then the latest PLCs but there is a lot of good engineering built into this device  which impressed me already. RsLinx works like magic. Also environment visually good. Regards  
  3. hi All I am trying to learn allen bradley PLC and i bought PLC-5 enhanced PLC/20. My first impression is very positive how powerful this PLC is for its age. My background is siemens so i am trying to learn allen bradley by youtube or reading manuals and also comparing to siemens s7. Any chance you give me your feedback please. PLC-5 seems to have 32 concurrent tasks which is similar to having 32 OB1s in siemens which is continuous task. This nearly blew my mind :) Does anybody know how this concurrency is achieved - is there firmware assigning each task a fixed time eg. 20ms and then jumping to another one? Does anybody know why PLC-5 is using octal system which is very unique I heard that allen bradley can simulate things in very sophisticated way using debug files - any chance somebody give me a gist a little bit? Why there are so many ways to use memory - half slot full or double? What is rack really - in siemens its just bunch on modules on a rack :) I also heard that allen bradley when simulating signals its doing it in unique way comparing to simplistic way in which rockwell allows simulation of inputs or outputs during testing - can you help me to get my head around this ? Is rockwell website my best source ? -of course apart from this forum :) Is there any place to find old, educational PLC-5 programs to understand - people dont seem to share it much i believe Regards
  4. FX3U-ENET-ADP how to connect and read strings?

    @AndreasW sorry for late reply. Massive thanks for your help. 
  5. hi All I am completely green in Mitsubishi PLC (i used to program siemens) but need kepware to connect to FX3U pls with ENET adp module. Could somebody pls help me with the very basics as kepware does not talk to the FX3U yet: What software do i need to read configuration/potentially do changes to FX3U and ENET? - is it free? How to check the port that the PLC is using - i assumed 5001 as default but it did not work- it is FX3 setting or ENET module setting? What kepware driver is best for the FX3 with ENET module? - at the moment ethernet driver seemed obvious choice to me Does ENET adp adapter can server only 1 connection at the time - is it hardware limit or something i can configure in the PLC? I will be trying to read strings from FX but how are these strings normally stored in mitsubishi FX3? - i found in the documentation that its either DSL  or DSH area - is it something that has to be configured upfront  or can i just use either DSL or DSH memory area? Massive thanks for any help upfront Regards
