Modbus RTU Communication via S7-317 2PN/DP

Post by alansal » Thu Nov 24, 2016 6:27 pm

Hello All,

As the topic says i need to communicate with another 3rd party via Modbus RTU. However i only have cpu (317-2EK14-0AB0 v3.2), no other CP343-1 etc. Is it still possible to read values?

If so, can it be done via standard blocks or do i need special software as well?


Thanks in advance.....
