Try to read the address not of IW304, but of PIW304. |

Thank you so much, I will try this out soon. I thought s7-300 was a powerful PLC? Why the low IO memory? |

For periheral addressing - check this. Some CPUs allow to increase size - see attachment. Increasing the size of the "Process image" increases the CPU cycle time. In the 90s and 00s, it really was powerful. Now the trend is S7-1500. |
