E3), then time t4i is allocated the measured time t4. For additional measurements, while A0
remains at 0, t4i is only re-saved if the measured time t4 is greater than the old value of t4i.
Supplementary conditions
The language commands SIRELIN, SIRELOUT and SIRELTIME may not be used in
synchronized actions.
The language command SIRELAY may only be used in synchronized actions of the SPL
(SAFE.SPF). The connection must be specified beforehand using the language commands
SIRELIN, SIRELOUT and SIRELTIME.
Example
