OK those settings should result is a +1.0V output
(as they do here)

Possible reasons for a very different output voltage:

1. Measuring wrong pins ( analog output 0 would be measured from TB3 pin 4 to TB3 pin 3)

2. Marginal 5V supply to 7I97T

3. Problem with the voltmeter

4. Damaged 7I97T analog output driver

5. 7I97T analog output connected to shorted  load

    • enable directly to the Rexroth DKC11.3 drive

You have basic7i97.hal in your .ini file but I think 
you wanted main. hal there instead.

That's why you get this error:

CANNOT FIND FILE FOR:basic7i97.hal

Thanks - of course -so simple i should have noticed it myself
Next error after changing name of hal in ini:

Debug file information:
Note: Using POSIX realtime
hm2_eth: rtapi_app_main: Resource temporarily unavailable (-11)
./main.hal:9: waitpid failed /usr/bin/rtapi_app hm2_eth
./main.hal:9: /usr/bin/rtapi_app exited without becoming ready
./main.hal:9: insmod for hm2_eth failed, returned -1
2077
Stopping realtime threads
Unloading hal components
Note: Using POSIX realtime

Why "temporarily" unavailable?

That typically means a connection issue

Either the link was not up when LinuxCNC started, the IP address was wrong or similar
