Dear All
I have worked with MODBUS TCP and RTU many times and commissioned successfully.
Here First time I m working with S7300 to establish communication between S7 300 CP 343-1 (As Client) and RTU (Server).First of all I checked the manuals and found the FB106, FB107 and FB108 need to be copied and configure FB 108 which call FB106 and 107 internally depends on whether we use it as Client or Server. I need to write some boolean values to the RTU and Read some boolean. But when download I am getting an error A090 i think this is related to license!! How I can skip this???
Also somewhere I found an another block FB101 which also can be usedto configure but don't have any manual for it searched a lot on the internet but did not found.
Can any one help me or guide me in this regards.
Thanks
Rahil
