Hi Everyone. I have the exact requirement for one client along with ET200 CPU.i have CPU 315-2PN/DP with 2 nos of ET 200M cpu's. I need to show the LED status of the CPU in my hmi. I have worked in the S7400H system before and i have achieved reading data from the Controller LED's via SFC51. But as far i know the SZL codes they mentioned in the SFC list only for S7 400 CPU's. I am not sure they will work in S7300 cpu since i do not have any CPU hardware in my hand. Please let me know how to achieve this requiement. Thanks... ------------------------------------------------------------------------------------------ |

hi, this works in the same way with S7-300 PLCs. have a look here: SIMATIC S7-300 Instruction list S7-300 CPUs and ET 200 CPUs chapter 10 hope this helps, regards, |
