2.3 Interfaces
Location and type of interfaces for predecessor devices and Comfort HMI devices
The Comfort HMI devices always have the same interfaces as the predecessor devices.
Exception : The RS-232 interface of the OP 77B predecessor device is not available for the
Comfort HMI devices.
The Comfort HMI devices have the following
additional interfaces:
● All Comfort HMI devices:
USB type Mini-B for commissioning with a configuration PC
● Comfort HMI devices as of KP/TP700 Comfort:
– Audio Line IN / OUT as of KP/TP700 Comfort, e.g. for connecting an audio amplifier
– Second interface USB type A, for connection of I/O devices such as printers or
keyboard
– Second interface PROFINET (Ethernet)
The following figure shows the interfaces on the predecessor devices of the KP400 Comfort
and KTP400 Comfort.
