3.7 Connecting the KTP Mobile connecting cable to the connection box
Mobile Panels 2nd Generation
74 Operating Instructions, 09/2018, A5E33876626-AC
The status of keyswitch and illuminated pushbuttons is evaluated immediately after
connection.
When you connect an HMI device to the connection box and evaluate operator controls
over PROFINET IO as direct buttons:
The status of the keyswitch, the illuminated pushbuttons and the corresponding LEDs is
evaluated immediately. This can cause unintentional responses.
Check the position of the keyswitch and do not activate the illuminated pushbutton before
or during connection.
1. Align the positioning mark of the connector with the positioning mark on the socket of the
connection box.
2. Connect the plug to the connection socket of the connection box.
Additional characteristics of the Mobile Panel are described in the section
"Testing Mobile Panel readiness for operation (Page 85)".
PROFIsafe-based F-system: Logoff required
In a PROFIsafe-based F-system, logoff from the safety program is required before
unplugging the connecting cable.
If you unplug the connecting cable without logoff, the plant will switch to a safe operating
state.
Hardwired F-system: No automatic emergency stop / stop bypass for connection box
compact and connection box standard
When unplugging the connecting cable from the connection box compact or a connection
box standard, there is no automatic bypass of the emergency stop / stop circuit. Without
further actions, an emergency stop or stop is triggered in the plant and the plant switches to
a safe state.
Take appropriate circuitry measures to prevent an undesired emergency stop or stop of the
plant.
For fail-safe HMI devices, see the section
"Fail-safe operation > Unplug connecting cable (Page 211)".
