SIEMENS SIMATIC S7-200 CP 243-1 – 6GK7243-1EX01-0XE0
The CP 243-1 is a communications processor designed for operation in an S7-200 automation system. It is used for connecting an S7-200 system to Industrial Ethernet (IE). The CP 243-1 also facilitates communication via Ethernet for the S7 product family.
As a result, S7-200 can be remotely configured, programmed, and diagnosed via Ethernet using STEP 7 Micro/WIN 32. Moreover, an S7-200 can communicate with another S7-200, S7-300, or S7-400 controller via Ethernet. It
can also communicate with an OPC server. In the open SIMATIC NET communications system, Industrial Ethernet is the network for both the coordination level and the cell level.
Technically, the Industrial Ethernet is an electrical network built on the basis of a shielded coaxial cable, twisted pair cabling, or an optical network using a fiber optic cable. Industrial Ethernet is defined by the international standard IEEE 802.3.
Industrial Ethernet is an integral part of the SIMATIC NET concept, which together with PROFIBUS and the AS Interface ensures continuous networking of the coordination, cell and field levels.
The CP 243-1 (6GK7 243-1EX00-0XE0) described here can be used for S7 communication. The CP 243-1 can be connected to various types of S7-200 CPUs
(222, 224, 226 and 226XM):
- CPU 222 Rel. 1.10 or higher (Rel. 1.20 or higher is recommended)
- CPU 224 Rel. 1.10 or higher (Rel. 1.20 or higher is recommended)
- CPU 226 Rel. 1.00 or higher (Rel. 1.20 or higher is recommended)
- CPU 226XM Rel. 1.00 or higher (Rel. 1.20 or higher is recommended)
A maximum of 2 expansion modules can be mounted on the CPU 222. In contrast, up to 7 expansion modules can be connected to the 224, 226 and 226XM CPUs. A detailed compatibility specification you will find in Appendix D
The CP 243-1 software is compatible with the following standards:
- S7 XPUT/XGET and S7 READ/WRITE
- S7-200 I/O bus specifications
The position in an S7-200 system in which a CP 243-1 can be operated depends
on the firmware version of the S7-200 CPU, see also chapter 3 (Installation)
