what are the full form of differnt timers

we use different timers in Simatic S5 PLC like
SF
SE
SS
and two more i dont remember their name
i know they are timer on delays and off-delays respectively but i want to know the full abbreviated full form of it,plz do mail me soon
Thankyou.

Per Step 7 help,

SS = Retentive On-Delay Timer Coil (analagous to S_ODTS)
SE = Extended Pulse Timer Coil (analagous to S_PEXT)
SF = Off-Delay Timer Coil (analagous to S_OFFDT)

Are you asking for the German translations from which those abbreviations derive?

I'm curious why the need for this info and that from your S5 post. Care to share?

SF is off-delay
SS is retentive on-delay
SE is extended pulse
SD is on-delay
SP is pulse
