Flowcode Support Board

Hi
I am trying to integrate Modbus TCP into my project, I have basically copied the Modbus TCP Part 1 video, where you set a coil on the Master and read the value of the coil on the Slave.
I am using two BL0080 boards connected by a cisco switch using the W5500 Wiz ethernet modules. I can ping both of my devices successfully, I have also used wireshark and I can see the TCP packets port 502 being sent when the switch is pressed on my master and acknowleged by the slave.
But my LED never illuminates on the slave, I have written a loop at the start of my slave programme which flashes the LED 10 times to check its integrity.
I have attached my Master and Slave programmes, I would appreciate any help.

Hello,

Only thing I can spot is the calculation in the master


should instead be
The program worked in the simulation for me after changing the IP. Might be worth trying the slave simulation with the hardware master and visa versa to see if you can nail down a bit more which side isn't behaiving as expected. The console window might be useful here so you can better see the communications being sent and received.

Hi Ben
Thanks for your reply, I have changed the calculation, and have tried using Master hardware and Slave simulation.
i have disconnected the W5500 module and used my interface 0 on the laptop with the IP address set to the Slave IP.
When I run the simulation the LED flashes 10 times to prove led functionality as expected, but I never get any RX/TX leds flashing on the Modbus Slave Icon or the Network Comms Icon .On the Console display for Modbus Slave I get the following:

Socket Open: OK
Listening: OK
Master Connected
Master Connected
Master Connected
Master Connected
Master Connected
Master Connected

But my LED does not repond to the master switch.
I assume the Rx/Tx Leds should flash on the simulation icons, but nothing happens on mine.
Am i doing something wrong, could you please point me in the right direction?
