RE: medm question of simDetectorIOC

The problem is almost certainly that EPICS Channel Access is not able to connected from the medm client to the simDetector IOC.

 

• Are medm and the IOC running on the same machine?
• Is there a firewall running on that machine?  If yes then it needs to allow ports 5064 and 5065 for UDP and TCP, or be disabled.
• If they are on different machines have you set any of the EPICS_CA_* environment variables?  Normally you don’t need to.

Hi all,

1. start IOC
../../bin/linux-x86_64/simDetectorApp st.cmd
2. start medm
  cd areaDetector/ADSimDetector/simDetectorApp/op/adl
  medm -x -macro "P=13SIM_1:, R=cam1:" simDetector.adl

The following picture shows the effect of medm after startup, why is there nothing in the picture?
