Using the Mobile Panel 277F IWLAN
Use
The Mobile Panel 277F IWLAN offers the possibility of having the mobile safety functions of
emergency stop and enable available at any point of a machine or plant. An effective range
limit has been implemented for the Mobile Panel 277F IWLAN. Depending on his location,
the operator obtains a safe, electronically monitored operator control enable.
The HMI device communicates with an access point via WLAN. Thus the operator can
operate the various machines or process cells without bothersome cable. The HMI device is
connected via the access point with a PROFINET network in which it communicates with an
F-CPU via the PROFIsafe protocol.
Sample installation - F-system with Mobile Panel 277F IWLAN
In the depicted configuration, each PROFINET IO device communicates with a single
PROFINET IO controller. In this example the Mobile Panel 277F IWLAN communicates
exclusively with the F-CPU as F-PROFINET IO controller.
