I have a S7-318 and 224XP with a profibus module. I can not communicate between the two of them. I have the hardware setup in the S7-318 as node 5 and the the I address is 400...415 and Q address 300...315(8 word out/8 word in) The V memory offset is 200. In the 224 the word that I am trying to see the the 318 is vd200. I've checked the profibus node on the module. I can see the vaule changing in the 224. I can not see the value in the hardware monitor/modify window. I'm thinking that i'm doing something wrong with the V memory offset or the address setup in the hardware configuration of the 318.
Thanks in advance for any help.
