Hello,
I am having trouble with MODBUS TCP communication. I am trying to read the input registers on a master.vi after a slave.vi has written to it. Attached you will find my slave and master vi's. I have made sure I had the correct IP address, same starting address for master and slave, and also the same port number. The input register is array size 4 and I've also wired that in on the master for the quantity to read. Could someone please give me some pointers?
Greatly appreciated!

I found my problem. I was missing the TCP communication in the slave.vi.
Thanks
