Application and properties

1.1

Using the CP

Application
The CP 243-1 is a communications processor intended for operation in an S7-200
automation system. It allows the connection of the S7-200 to Industrial Ethernet (IE). The
use of the CP 243-1 means that communication via Ethernet is also possible at the lower
performance end of the S7 product family.
As a result, an S7-200 can be configured, programmed and diagnosed even at a distance
using STEP 7 Micro/WIN 32 via Ethernet. Using a CP 243-1 also means that an S7-200 can
communicate with another S7-200, an S7-300 or S7-400 controller via Ethernet.
Communication with an OPC server is also possible.
The IT functions of the CP 243-1 form the basis for monitoring and, if necessary, also
manipulating automation systems with a Web browser from a networked PC. In addition,
diagnostics messages can also be e-mailed from a system. Using the IT functions, it is very
easy to exchange entire files with other computer and controller systems.
Industrial Ethernet is the network for the process control level and the cell level of the
SIMATIC NET open communication system. Physically, Industrial Ethernet is an electrical
network based on shielded, coaxial lines, twisted pair cabling, and an optical network of
fiber-optic conductors. Industrial Ethernet is defined by the international standard IEEE
802.3.

Compatibility with predecessor models

Predecessor models
The CP 243-1 (6GK7243-1EX01-0XE0) described here is the successor to the predecessor
models CP 243-1 (6GK7243-1EX00-0XE0) and CP 243-1 IT (6GK7243-1GX00-0XE0) and is
fully compatible with them.
