Completely configurable application through "data point configuration"

The introduction of "data point configuration" in STEP 7 eliminates all programming effort for transferring 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-driven transfer of measurements, setpoints or alarms can be implemented in just a few steps and without programming effort.

Data buffering

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

In the event of a connection failure, up to 100,000 time-stamped values are buffered. When the connection is restored, the buffered values are automatically transferred to the control center in the correct chronological order.

E-mail alerting

E-mail alerts can be configured for prompt notification of service and maintenance personnel about station conditions. When previously defined events (such as threshold violation) occur, application-specific information is sent automatically by e-mail.

Diagnostics

The CP 1542SP-1 IRC 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 on the CP via LEDs.

Extensive information such as connection history, buffer status and transferred measured values can be called up via STEP 7.

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.

Interfaces

The CP 1542SP-1 IRC has 2 Ethernet interfaces for connection to the control center. The ET 200SP Distributed Controller can be connected via an existing network or via other media by using additional routers (e.g. SCALANCE M for connection to the Internet via DSL).
