Hello vghvghadam; What is the address you are trying to control? In Siemens S7-300 CPUs, this address should use peripheral addressing (with a preceding "P"), since analog outputs (and inputs) are outside of the image tables of the CPU, and generally start around address 256. Where and when do you need peripheral addressing? https://support.industry.siemens.com/cs/ww/en/view/18325417 So look in the hardware configuration the address selected for the analog output, let's say it is 272, then you should address it in your code as PQW 272. If this does not help you, please post a screenshot of the code that is giving you trouble, so we can examine it. Hope this helps, Daniel Chartier |
