The CP 1243-1 PCC (Plant Cloud Connect) is a communications processor for the safe connection of the SIMATIC S7-1200 via the public infrastructure (Internet, DSL) to a Siemens Operation Center. The connection to an Operation Center is made in the context of Siemens Plant Data Services.

The CP transmits the data provided for the services via a safe connection to the Operation Center. In order to obtain a prediction about the status of your plant or your devices, the Operation Center collects and analyzes the plant information received in this way.

Completely configurable application through "data point configuration"

Using the "data point configuration" feature in STEP 7 eliminates the need for any programming effort for the transfer of data to the Operation Center.

The data of the CPU relevant for the Plant Data Services is selected by means of 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.

Diagnostics

The CP 1243-1 PCC offers comprehensive diagnostic options for a quick and informative analysis of the station status. Elementary diagnostic information about the connection to the Operation Center is signaled directly via LEDs at the CP.

Using STEP 7, comprehensive information can be retrieved, such as facts about the connection history, buffer status, and 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.

Stateful Inspection Firewall

By using a firewall, the 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.
