Hello Design Tech; In the following FAQs you will find a sample configuration of a CP 342-5 as a Profibus slave (to a S7-300 CPU as master), and an explanation of DP_Send amd DP_Rcv functions required for cdata exchanges between the CP 342-5 and the CPU it shares the rack with (not the DP master on a seperate rack). DP link between CP 342-5 (slave) and S7-300/400 (master) with STEP 7 V5.1 https://support.industry.siemens.com/cs/ww/en/view/6519580 With the CP 342-5 you must always use the functions FC1 and FC2 for data transfer from the CPU to the CP... What should you watch out for when configuring a CP342-5 as DP master and why is it necessary to call the FC1 'DP_SEND' and FC2 'DP_RECV' functions in the user program of the CPU in order to transfer data? https://support.industry.siemens.com/cs/ww/en/view/18208090 Hope this helps, Daniel Chartier |
