Function
The CP 1243-1 DNP3 is a communication module for the
S7-1200. The module allows the S7-1200 to be connected as a
remote station to a DNP3-based control center in just a few
steps.
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 alerting
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 1243-1 DNP3 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, comprehensive information can be retrieved,
such as connection history, buffer status, and the transferred
measured values.
DNP3 protocol
Communication with the control center is based on the estab-
lished standard of DNP3 specification 2 (2007/2009).
Thanks to support of the object and data transfer mechanisms
defined in the specification, compatibility with PCS 7, WinCC
(with applicable telecontrol packages), and all other control cen-
ter systems available on the market is warranted.
The security mechanisms already defined in the DNP3 standard
for secure data transfer through trunk networks are fully sup-
ported.
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 1243-1 DNP3 has an Ethernet interface to connect to the
control center. The S7-1200 can be connected via an existing
network or via other media by using additional routers
(e.g. SCALANCE M for mobile wireless communication).
Power supply
Extra wiring for the CP power supply is not required. Power is
supplied directly via the backplane bus of the S7-1200.
