Trigger type: "Symbol"
"CAS/MTS"
Collision Avoidance Symbol / Media access Test Symbol. These sym-
bols are identical and can be sent in the optional symbol window at
the end of a communication cycle. They are used to avoid collisions
during the system start.
"Wakeup Pat-
tern"
The wakeup pattern is sent to activate the nodes of the system.
Remote command:

"Header CRC"
Error in a cyclic redundancy check code of the header data which
covers mainly frame ID and payload length.
