Hi everyone - my first post here. I have a customer with a SLC5/01. The controller is 1747-L511. Battery seems good. The fault LED is flashing. I tried to connect to it using RSlogix500 and I got this message (photo1). I selected 'Load From EEPROM' and got this notice. (photo2) Customer has the printed ladder but I can't tell which data types are what. everything is just numbers - no B's, no I's and no O's. the timers and counters are just numbers too. Luckily the printed ladder has a cover sheet, which led me to the PLC2.(photo3) The rack has two 8 channel inputs and 2 8 channel outputs. I would like to replace everything with a micrologix 1400 or something, if I could translate the code. Can anyone advise on this matter please?
