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

Problems with Axon as Modbus Slave
Polarity of RS485
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?
RE: Problems with the onboard IO in Mervis
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.
Problems with the onboard IO in Mervis
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
