Overview
DNP3 (

manufacturer-independent telecontrol protocol.
To implement a telecontrol system with DNP3 protocol,
substations (RTU) can be set up based on SIMATIC.
The CP 1243-1 DNP3 for SIMATIC S7-1200 and the Telecontrol
Interface Modules (TIM) for SIMATIC S7-300/400 are offered
for this.
Telecontrol communications processors
CP 1243-1 DNP3
The CP 1243-1 DNP3 (DNP3 protocol) is an Industrial Remote
Communication module for the telecontrol substation with
SIMATIC S7-1200. It has an RJ45 interface, which allows
communication over IP-based networks.
The TIM telecontrol communications module
TIM 3V-IE DNP3
The TIM 3V-IE DNP3 (DNP3 protocol) is a SINAUT communica-
tions module for the telecontrol substation with SIMATIC S7-300
and, as a station module, can be directly connected via the
Ethernet to a PC as a DNP3 control center. It has an RS 232
interface to which a suitable external leased-line, radio or analog
dialup modem can be connected. It additionally possesses an
RJ45 interface, which permits communication over IP-based
networks. On the TIM 3V-IE DNP3, both interfaces can be
operated simultaneously, e.g. to implement path redundancy to
a DNP3 control center.
TIM 4R-IE DNP3
The TIM 4R-IE DNP3 (DNP3 protocol) has two RS 232/RS 485
interfaces for data transmission via conventional WANs (copper
dedicated line, analog dialup modems, wireless) and two
additional RJ45 interfaces for connection to IP-based networks
(WAN or LAN).
This TIM can be used as a communication processor in a
SIMATIC S7-300, but it is especially suitable as a telecontrol
module for a SIMATIC S7-400 or SIMATIC S7-400H. In this case
it is connected to the S7-CPU as stand-alone device via one
of its two Ethernet interfaces. The module can be configured as
a station, node or master module. As a station module, it can
be directly connected to a PC over Ethernet as a DNP3 control
center.
The four transmission paths can all be different and operated
independently of one another, but also in any redundant combi-
nation.
