Hi Lauri,
this node contains native c parts which will be compiled internally while installing.
This mechanism is not active in ctrlX due to security issues with this mechanism.
We recommend to use for Modbus our PLC and the PLC library we have for Modbus.
Alternatively you can build the package external with the node package manager.
By the way, the correct version would be 1.14, the RM22.03 decleration is just internally.
Regards
