Version Changes
IEC The number of clients for a report has been increased:
An unbuffered report (urcbA … urcbP) can be allocated
to max. 8 clients (previously: 1), and a buffered report
(brcbA … brcbH) can be allocated to max. 4 clients
(previously: 1).
OUTP Bug notice: With version P63x -650 the test operation
of output relays can be executed independent from the
off-line state of the device!
MAIN The previously available parameters (003 039) MAIN:
Warm restart und (000 085) MAIN: Cold restart
have been relabeled MAIN: Soft Warm restart and
MAIN: Soft Cold restart, respectively. They still
trigger a 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.)
For a restart including hardware tests, the following
new parameters can now be used:
●
(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).

functionality), so that they have now been removed:
●

●
(221 106) COMM1: Test position dev.
