<![CDATA[Nibe Fighter 1130 with RCU 11]]>Hi!

I have just baught myself a ground heater with an attached RCU 11. I'm a total novice on modbus TCP to make that clear.

What I am looking for is a simple way to pick up values from the heater. In my knowledge they should be in holding registers. (Accordning to http://www.nibe.se/Pages/42625/RCU_Parameterlista_F1135_1235.pdf (In swedish, but in tables)

I have tried to configured mango, but when i enable the modbus IP in databases I get the following errors..

ERROR 2010-03-29 21:36:33,593 (org.quartz.core.JobRunShell.run:211) - Job com.serotonin.mango.rt.dataSource.PollingDataSource.PollingDataSource-1 threw an unhan

ava:525)

My configuration is
Transport type: TCP
Host: (Entered the IP adress)
Port: 502

I added one point.
Slave ID: 1
Register range: Holdning register
Modbus data type: 2 byte signed integer
Offset: 2 (Wich should be "Produktkod" or "Varmvattentemperatur (mantelgivare)" accourdning to Nibe
Settable: unchecked
Additive: 0

I guess it is something very obvious.
I have tried to make contact with another application that is using modbus and I get some results, so there is no network problem.

I've tried the 1.8.1 download on Windows and Mac using the available download and install instructions, and accessing a Modbus TCP slave, and it works perfectly. If this continues to be a problem for you i can only suggest you wait for the 1.8.2 release, forthcoming once some details with a collaborator are worked out, hopefully in a matter of weeks.

Deleted the whole tomcat directory (First copying the files that where posted here)
Extracted tomcat to c:
Extracted mango to C:\tomcat\webapps\ROOT
Started tomcat with c:\tomcat\bin\startup
logged in with admin
added a datasource (Modbus IP)
Added a point (Holding register)
Enabled the datasource and did got the error as explained earlier...

Did you use 1.8.1 out of the box, so to speak, or did you update anything about it? The thing is, i can't reproduce the problem with the version that is on the download page right now.

There appears to be a problem with the Modbus implementation version that you have. Try replacing WEB-INF/lib/modbus4j.jar with the attached version, restart, and see if that helps.
