Core 2.1 Modbus I/P data source error
-
Background:
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.Problem:
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.ModbusIpDataSourceVOI 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.
Thanks. -
Hi Glen,
Did you clear your browsers cache? Here are the upgrade instructions in case you missed them: http://infiniteautomation.com/index.php/download/2-uncategorised/98-upgrade-instructions

Hi Joel,
I switched browsers from IE to Firefox, but no help (of course MS updates installed IE11..).
I did find the problem...
JRE1.6 was installed, and the partially allowed Mango to function.
I installed JRE1.7 (client version) and had no functionality at all...
So I installed the server version of JRE1.7 and now seem to have everything I need immediately working fine.Thanks for your quick response.

That is interesting. Also make sure you have JDK 1.6 or 1.7 installed and you may need to set a JAVA_HOME environmental variable pointing to the JDK installation.

Joel, yes I did have to set JAVA_HOME as well.
Quick side question - where can I change the Mango web server port from 8080 to another port ... 9999 for eample?
-
It's in the /classes/env.properties file.
