Coexistence of the frequency bands

Coexistence in the 2.4 band

The use of the HMI device does not affect the communication with other devices or only

negligibly so. This applies to the following communication networks:

● WLAN

When adding a WLAN participant, make sure that you observe the conditions described

in the document "Wireless LAN in a PROFINET IO Environment". The conditions vary

depending on the operating mode and the requirement for PNIO refresh times. See

Guideline for the Use of Industrial Wireless LAN in a PROFINET IO Environment

(http://support.automation.siemens.com/WW/view/en/31938420).

● Standard RFID system according to ISO 15693

● Communication protocols that are used for office networks, smoke detectors, bar code

scanners etc. in the 2.4 GHz range

You need to plan the radio channels when operating such devices simultaneously in the

2.4 GHz band – see "SCALANCE W-700" configuration manual

(http://support.automation.siemens.com/WW/view/en/32816761)". Otherwise sufficient

bandwidth for communications cannot be guaranteed.

● ZigBee devices

Coexistence with other communication networks

Moreover, coexistence is ensured for the following communication networks:

● Coexistence in the 5 band

Planning for the radio channels of all WLAN systems in use is required to ensure

sufficient bandwidth for communication.

● WirelessHART

You need to plan for the radio channels for simultaneous operation of Industrial Wireless

LAN systems and WirelessHART systems in the 2.4 GHz band. Avoid simultaneous use

of overlapping frequency ranges. There is overlapping between Industrial Wireless LAN

and WirelessHART – see "SCALANCE W-700" configuration manual

(http://support.automation.siemens.com/WW/view/en/32816761), section 2.3.
