Hell the Boss you HWconfig looks ok, but the attached example does NOT have the S7 program in it. My guess is the problem lies with your handling of the DP_SEND and DP_RECV calls. Have another look at the link that Wizard mentioned and bear in mind especially the followingconcerning your setup: You highest Output address for the DP/DP coupler (on the CP342-5 side) is 691. This meansyour DP_SEND DB must be 692 bytes long. Similarily, your DP_RECV DB must be 596 bytes long (highest Input address is 595, you always start with I/Oaddress ZERO if you use a CP342-5 and this is commonly misunderstood). I hope this helps |
