Behaviour after power failure
Storage in non-volatile EEPROM for structure, configuration, pa-
rameter setting and adjusted setpoints.
Storage in a capacitor-buffered RAM (typ. > 15 minutes) for data
of time functions (programmers, integrators, counters, ...)
Real-time clock(Option B, RS 422)
Buffer capacitor provides back-up for at least 2 days (typical).
Bus interface ( Option B)
TTL and RS422 / 485-interface
Galvanically isolated, choice of TTL or
RS 422/485 operation.
Number of multi function unitsper bus:
With RS 422/485: 99
With TTL signals: 32 interface modules (9404 429 980x1). Address
range ((00...99)See Documentation 9499-040-82911) .
