Hi rogabob, In the hardware configuration, you put the values that you need? In the user program you put a value for the exit? L 10000 T PQW Have a look: SIMATIC S7-300 CPU 31xC and CPU 31x: Installation |

Hello rogabob; Welcome to the forum. What addresses are you using to interface with the integrated IOs of your CPU 314C-2DP? Have a look at the attached document, and look at the posts by Marcjan in the following discussion: S7300 cpu 314 c2 dp integrated analog I/O configuration Once you have connected through the right addressing, continue reading in the earlier thread about the scaling (analog input)/unscaling (analog output) functions available for reading and writing abnalog signals in these registers. Hope this helps, Daniel Chartier |

But you have created OB1 in the user program and have written the value and transferred to PQW? |
