Eberle pls 508

Eberle pls 508

(OP)
Dear all,

I have a dead PLS508 and now I'm into translating the PLC
program to Simatic S5 (or S7) and what I'm missing is how
Timers and Counters work.
If there's anyone out there who has programmmed Eberle PLC:s
in the past I'd be most grateful for any input here.

Example:
L E 0.1 #START BY START PLUS
L KW 1
= TWB 0 #TWB TIMEWORDBASIS
L KW 80
= TWO 0 #TWO TIMEWORD
= TI 0 #TI0 TIMER PULSE

If I understand it correctly this gives a 1 shot pulse on
timer TI 0 for every positive rising edge on input 0.1.
How does the timewordbasis work here, is 0 for 1/100:s of
seconds?
Timeword 80, is that in Decimal?

My free translation into S5 would be:

A E 0.1
L KT 80.0
SP T 0

This would trigger a 1 shot pulse on timer 0 for every rising
edge of input 0.1.
Pulse duration = (max) 0.8 S, provided of course that input
0.1 stays on during atleast 0.8 S.

Thanks.
