Industrial Wireless Communication

WirelessHART

IE/WSN-PA LINK

Increased availability of WirelessHART application

due to redundancy mode

For increased availability requirements, the link can be used re-

dundantly. The redundancy function is only available for the de-

vice variant with a connection for an external antenna.

Two links are connected to the same Ethernet subnet via a

switch to provide the redundancy. The two links are connected

to each other via an Ethernet cable (management coupling).

One of the two links is configured as the active device. It carries

out the communication between the control center and the

WirelessHART wireless network under normal conditions. The

second link is configured identically. It is used as a standby

device. In a redundancy scenario, the standby device becomes

the active device.

Integration

Integration into automation systems

The IE/WSN-PA LINK can be integrated into automation systems

via Ethernet or Modbus TCP. Communication modules

(CP 343-1 or CP 443-1) are required to connect the

IE/WSN-PA LINK to SIMATIC S7-300/400. Function blocks

and technical support can be found at:
