i installed AXON in exchange station and now i need change PLC program. But i cannot connect PLC and when i start deploy solution, it write that PLC is only partially connected.
How can connect the PLC without going to external place?
i use the my own protocol on RS485 line, normally i get from
function io.getportstatus(handle) value 0. Sometimes i got
34 in other way 31, but this values is not described in manual.
When i got this value, i cannot continue to read until restart.
is somewhere sources of this function to analyse problem?
the file /etc/apt/sources.list:
#deb http://ftp.debian.org/debian stretch main
deb https://files.unipi.technology/debian stretch main
do you have now problem with repository access?
E: Failed to fetch https://files.unipi.technology/debian/dists/stretch/InRelease Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)
E: Some index files failed to download. They have been ignored, or old ones used instead.

Hi , ok i need Modbus Master (CLI application running outside Mervis) to transfer to/from Modbus Slave (part of Mervis ???).
I would prepare some variables inside my application to be accessible from outside (as i wrote before, to transfer to IS).
Thanks for answer, i use the ModBus TCP, is any cli server in Unipi repository?
I modify my cron script to transfer setting from ftp file to Mervis registers and on other side transfer measured data from Mervis to local file. This can works without modification on server side, where is now more complicated solution.
