Verification checks on linuxRT machines:

  • Please see $IOC/cpu-<bld>-<name>/README on instructions on how to power cycle machines remotely through the use of ipmi commands
  • Once you set-up your linuxRT machine and boot up, log in as laci to your linuxRT system. ( ssh laci@cpu-<bld>-<name>)
  • Test if your machine is running real-time linux using  uname -a

...

# ===================================================================

# Now we start the ethercat scanner process under the linux screen program:

# This will allow us to attach/detach to our Ethercat scanner process

# ==============================================

cd $EPICS_IOCS/cpu-b084-hp03

su laci -c $EPICS_IOCS/vioc-b084-tmp1/scannerStartup.sh

# =================================================

 


Verification checks on linuxRT machines:

  •  Test if your machine has the Etherlab EtherCAT driver module loaded.

...

# ==================================================================================================

# Load Additional databases:

# ==================================================================================================

# Load the database templates for the EtherCAT components

# dbLoadRecords("db/<template_name_for slave_module>, <pass_in_macros>)

dbLoadRecords("db/EK1101.template", "DEVICE=TEMP:BCM_EK1101,PORT=COUPLER0,SCAN=1 second")

dbLoadRecords("db/EL3202-0010.template", "DEVICE=TEMP:BCM_EL3202,PORT=ANALOGINPUT,SCAN=1 second")


Verification checks on development machine (preferably lcls-dev3):

Check that your python version is correct (the scripts used to generate the chain.xml are python-based):

    • Python version: Python 2.7.9
    • export the correct version to the path

 $ python --version

 Python 2.7.4

$ export PATH=/afs/slac/g/lcls/package/python/python2.7.9/linux-x86_64/bin/:$PATH

$ python --version

Python 2.7.9


Debugging Tips

  • Check that the ethercat kernel module is installed: ls /dev/EtherCAT0

  • Manually start scanner process on EtherCAT Master (linuxRT machine)

    On a linuxRT machine:

    <path_to_scanner_binary> -f <rate_in_hz> <path_to_scanner_xml> <path_to_unix_socket_created_by_scanner> <max_message_size>
     
     Example (from directory containing scanner binary):
    ./scanner -f 100 ../../etc/scanner.xml /tmp/sock1 100
