Hi Andrew,
me again. Epics4 works now for me, everything solved with some hints of michael.
The problem of camonitor with specifying a deadband:
I got from camonitor the following. The multiple servers could be a problem, but I do not know how to get rid of it in my centos with virtualbox.
EPICS_CA_ADDR_LIST=localhost has been specified
I get after starting the softioc
camonitor ACM:TEST:AO.{"dbnd":{"abs":1.5}}
ACM:TEST:AO.{dbnd:{abs:1.5}} <undefined> 0 UDF INVALID CA.Client.Exception............................................... Warning: "Identical process variable names on multiple servers" Context: "Channel: "ACM:TEST:AO.{dbnd:{abs:1.5}}", Connecting to: 10.0.2.15:5064, Ignored: osboxes:5064" Source File: ../cac.cpp line 1320 Current Time: Sun Oct 03 2021 04:22:15.964251792 ..................................................................

I can’t seem to replicate your issue. I’m using this database:
Here’s me starting the soft IOC and writing to the records:
and here’s what my camonitor output looked like. I started it immediately after the softIoc, before the first dbpf command above:
The first two lines that show the undefined timestamp and UDF/Invalid alarm give the initial channel values as zero, then after testing with 10 and 0 there were no monitors posted until the value went over the deadband.
If you’re seeing something different, can you post your complete output from camonitor?
