The CP 1243-7 LTE is a communication module for the S7-1200. The module allows the S7-1200 to be connected as a remote station to the TeleControl Server Basic via cellular phone in just a few steps.

Connection of S7-1200 to Telecontrol Server via mobile wireless and DSL internet access

Completely configurable application through "data point configuration"

The introduction of the "data point configuration" in STEP 7 dispenses with all programming effort for transfer of data to the control center.

The data of the CPU relevant to the control center is selected via user-friendly "item browsing" in STEP 7. In a clearly-arranged menu, the data transfer parameters are then assigned to the data points selected in this way. The cyclic or event-controller transfer of measurements, setpoints or alarms can thus be implemented in only a few operations and without programming effort.

Data backup

Data losses are prevented by the data buffering mechanisms integrated in the product.

In the event of a connection failure, up to 64,000 time-stamped values are buffered. When the connection returns, the buffered values are automatically transferred to the control center in the right order.

E-mail notification

Alert e-mails can be configured for timely provision of stations' states to service or maintenance personnel. If previously defined events (such as threshold violation) should occur, application-specific information is sent automatically by e-mail.

Diagnostics

The CP 1243-7 LTE offers comprehensive diagnostic options for a quick and informative analysis of the station status. Elementary diagnostic information about the connection to the control center is signaled directly via LEDs at the CP.

Using STEP 7 and the Web server, comprehensive information can be retrieved, such as connection history, buffer status or the transferred measured values.

Remote maintenance

For remote access from the control center to the substation, the CP provides a remote maintenance port in parallel with process operation. This ensures access for monitoring and program changes.

Virtual Private Network (IPSec)

The connection of S7-1200 via a VPN network ensures that authenticated network stations can communicate with the controller. Secure encryption of the data and verification of the data integrity protects the data traffic from espionage and manipulation.

Stateful Inspection Firewall

By using a firewall, S7-1200 can provide additional protection against unauthorized access and manipulation attempts. The firewall filters data packets and checks the communication connections in accordance with the filter list. Both incoming and outgoing communication can be filtered based on IP and MAC addresses.

Web server access

Access to the Web server of the CPU via the mobile wireless interface for easy diagnostics.
