with Modbus RTU protocol that is fit-
ted into the top-hat DIN rail.
Devices with option system interface
can be connected via bus coupler to
fieldbusses.
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.
