HI everyone

I have read through some posts regarding communication between 1200 and 300 CPU's using the Get block .It seems as if everything is set up correctly in my project .I have attached some screenshots of my setup .The problem is that when I trigger  REQ to read the data I dont get any error or signal change at NDR .It seems that nothing is happening and also looking ath my DB the data is not being read from the 300 station. I have checked and re-cheked ,but dont see any issues .

One thing I notice is that when I go online and look at my GET_DB , I dont see any value at RD_1 as configured in the program .Is this normal ?

hope someone could assist .

Thanks

Hi,

did you check the IP Adress. Local you have 10.30.2.202 and Partner 10.30.0.197.

Can you ping both adresses?

You can also check this FAQ, that´s exactly your topic:

How do you configure and program an S7 connection and the FB15 "PUT" and FB14 "GET" function blocks for data transfer between an S7-1200 CPU and an S7-300 CPU?
