Version Changes
MAIN The previously available parameters (003 039) MAIN:
Warm restart und (000 085) MAIN: Cold restart
have been relabeled to MAIN: Soft Warm restart
and MAIN: Soft Cold restart, respectively. They still
restart of the device, but now the hardware tests are
not carried out anymore during the startup phase. (This
way the restart needs less time.)
The restart including hardware tests is now made
available by the following new parameters:
●
(010 166) MAIN: Warm restart
●
(009 254) MAIN: Cold restart
LOG_2 There is a new function group LOG_2 (Programmable
Logic 2). It is identical to the previously available
function group LOGIC, but it offers only four logical
equations. These, however, have long-term timers,
settable from 0 to 60000 s (= 16 hours, 40 minutes).
