TCP variant of Ethernet Send and Receive function block
In Freelance V2013, AC900F and AC700F supports TCP variant of Ethernet Send and Receive (SRTCP) function blocks to transfer data between freelance controllers in different projects. But in V2016, it is not supported in AC900F and AC700F. What is the workaround to convert SRTCP blocks used in V2013 while upgrading to V2016.

Hello Govindaraj,
Modbus TCP would come to mind as a replacement. One would have to cope with the limited data type supported by Modbus TCP though. Bool or word variables are supported by Modbus TCP as coils or registers. For floating point values (4 Byte) you would need to convert them to 2 x 16 Bit values (RTOME function) which can be transported by Modbus TCP. The other direction, to re-combine the two register values back to a float is called METOR.

Where did you find that Freelance 2016 does not support SR_TCP any more?

Thanks. Was wondering because I could configure them in 2016. Now it is clear.
