Moreover, the CI 45 can exchange
data with superordinate systems and
PCs via an optional RS 485 interface
with MODBUS RTU protocol that is fit-
ted into the top-hat DIN rail.
Password protection
If required, unauthorized access to the
various Operating Levels can be pre-
vented with a password, or an entire
level can be blocked.
