Hi again, I can turn on the panel with a third party software with another computer. Now I want to send the magic packet with my s7300 CPU. How can I send the magic pocket? which block? How can I send a packet through ethernet to a MAC address? Thanks for your help, Bests, Ali ------------------------------------------------------------------------------------------ |

Hello Ali; The only protocol that will connect to MAC addresses supported by the S7-300, is ISO transport. It requires an Ethernet CP 343-1, the list of which is presented in the second document below: - What properties, advantages and special features are offered by the protocols TCP, ISO-on-TCP, UDP and ISO Transport? https://support.industry.siemens.com/cs/ww/en/view/26171811 - How do you configure the WRITE and FETCH services via Industrial Ethernet (ISO transport connection, ISO-on-TCP connection) for the S7-300/400 with Industrial Ethernet CP343-1 or CP443-1? https://support.industry.siemens.com/cs/ww/en/view/1853547 I have never done such a connection between a S7-300 CP 343-1 and a PC, normally ISO transport is used for WRITE and FETCH functions between CPs of S5 and S7 CPUs. So the following must only be considered as a suggestion: You will have to determine how the "magic packet" is constructed, probably by analyzing the transmission between the PCs you are using now, with wireshark for example. Then you will have to build it inside a DB in your S7-300. You will have to establish a Netpro connection between the CP 343-1 and your PC, over ISO transport. Once you have done so, and established the link using the PC's MAC address, you should be able to use the ISO transport WRITE function to send the "magic packet". Good luck in this project. Hope this helps, Daniel Chartier |

Hi dchartier, Thanks for your reply, I have found the data structure of the "magic packet" and I cannot send it to the PC. does ISO-on-TCP just work with communication modules???? CPU does not support FETCH and WRITE services? Can I send it via Ethernet port on my CPU?

Closed cause question posted twice. The second thread with the subject Turn On/Off a iPC277E Panel PC with a S7-300 is published within the conference Communication / Networks. Best regards,Jen_Moderator |
