Hello
I'm trying to use my Axon as Modbus Slave.
I have added an Serverchannel and added here my "device" with one register.
I'm not able to get the data from this device.
What did i wrong!
On Masterside (which is actual an RS485 USB Dongle + Analyzer) i don't get an answer of the Axon.
Thanks a lot

Hello
I'm using an Axon L505 with the Mervis Software and I am trying to communicate over Modbus with a Slave.
I have investigated, that i have to change the polatiy of the Port 1.3. Is there anywhere in the Software a possibility to flip the polarity?
Thanks
Sebastian

I've found out my problem.
In the tutorial an neuron was added at the modbus tcp, but i haven't realised, that the neuron is also the PLC.
Now i have added an ModbusTCP channel with the L505 and now the IO works.

Hello
I'm very new with the Mervis Software but i'm an experienced PLC programmer.
I have the problem, that i can't access the build in IO of the Axon L505. It could be possible that i didn't see the trick. I've tried the tutorial provided by unipi, but there directly is a modbus tcp slave attached and not the build in io were used.
Could anybody give me the advise how to connect these.
Thanks a lot
Sebastian
