Application And Properties; Connecting The S7-1200 To A Mobile Wireless Network - Siemens CP 1243-7 LTE Operating Instructions Manual

Application and properties

1.1

Connecting the S7-1200 to a mobile wireless network

The CP is intended for use in industrial environments.
Mobile wireless standards, frequency bands
Using the CP, the S7-1200 SIMATIC controller can be connected to mobile wireless
networks of the following standards:
● CP 1243-7 LTE-EU
The CP supports the following mobile wireless standards:
– LTE
– UMTS
– GSM
● CP 1243-7 LTE-US
The CP is certifies by AT&T supports the following mobile wireless standards:
– LTE
– UMTS
– GSM
You will find the supported frequency bands in the section Technical specifications
(Page 133).
Unless explicitly stated differently in the following manual, the telecontrol communication
relates to connections to a telecontrol server with the application TCSB (TeleControl Server
Basic V3).
Changing the mobile wireless standard if the network is not available
If the establishment of a connection via a mobile wireless network with the LTE standard
fails, the CP attempts to dial in to an available network with the next lower mobile wireless
standard. The following fallback behavior applies:
● CP 1243-7 LTE-EU: LTE → UMTS → GSM
● CP 1243-7 LTE-US: LTE → UMTS → GSM (if network exists)
This is only possible if the corresponding mobile wireless standard is enabled in the
configuration of the CP.
National approvals
In countries in which the CP is approved, you will find this on the Internet on the pages of
Siemens Industry Online Support. You will find the link in the section Approvals (Page 139).
