[Unit]
Description=CoDeSys 3 runtime
# - multi-user.target is required to ensure codesys only runs when all
# other stuff like logins&co are ready
# - we cannot use application.target here since it causes a dependicy loop
# - getty.target is required so we wait until all logins are active,
# including those using the serial lines, before we start cdesyscontrol,
# which itself might mess with the serial lines
After=basic.target local-fs.target multi-user.target getty.target var-dyn.mount var-stat.mount
Requires=systemd-modules-load.service ubi-check-partitions.service var-dyn.mount var-stat.mount
Conflicts=testing.target emvtest.target maintenance.target
