Was running Core 2.03 and Modbus I/P (both unlicensed). Had five Modbus I/P data sources setup with less than 20 registers each. Worked fine.
Decided to upgrade to Core 2.1 and associated modules as I want to move to licensed versions.
Had problems upgrading, so uninstalled 2.03 and installed 2.1 then setup one Modbus I/P data source with five registers. Works fine.
Tried to add a second Modbus I/P data source, but when trying to save the Modbus IP Properties, get the following error:
com.serotonin.m2m2.http.vo.HttpReceiverDataSourceVO cannot be cast to com.serotonin.m2m2.modbus.vo.ModbusIpDataSourceVO
I have restarted the instance a few times.
I removed the HTTP data source and restarted the instance, then tried again to add a second Modbus I/P ds, but now get "A server error has occured".
Any help is appreciated.
