2.32.8 Special Features
If the system time is put forward (e.g. after a system HALT and advancing the time),
VISONIK updates all those Time Reactions which should have been executed during
this skipped time.
Exceptions:
–
On system start with BOO,Z
–
On generating/changing the system time/date (in Function DATE), and the user has
set "Update Date & Time Reactions =NO".
–
In Macro Reactions (MC) if there has been a break in system time of more than 2
hours. Only a message is given to say that VISONIK has suppressed the Macro
command.
This rapid updating of time reactions can, under certain conditions, lead to uncontrolled
switching of various plant equipment, particularly if many time reactions should be
updated.
To avoid such circumstances all command outputs (switch and position commands)
related to Time Reactions are inhibited during updating! Once updating is finished only
the resulting setpoint is output so that the peripheral plant state agrees with the actual
set state.
