  Dear Rudy and Thomas, I has a similar problem with tornado, toro, and jsonrpclib getting loaded into Python 3.5. I got around this problem by changing the following line in install-evok.sh file: "pip install tornado toro jsonrpclib" to "/usr/bin/pip-2.7 install tornado toro jsonrpclib" It forced the install to Python 2.7 libraries I updated build-essentials and python-dev for 2.7 (and all other versions) first: "sudo apt-get install build-essential python-dev"

  Hello @lessmann, the limit of how many devices can be connected to one RS485 line comes from the RS485 transceiver (the chip on the RS485 output) and on our PLCs it is 32. But be aware, that this is just a theoretical limit and the real limit depends on the current situation. Second limit of the RS485 is the speed of the communication. Since RS485 is a half-duplex type of communication (master can speak only to one slave at a time), the more devices you have the lower speed of updates you will have. If you have PLC with more RS485 ports, you can split the extensions into groups. Best regards, Martin
