CPU Description
CPU 222 Rel. 1.10 or greater CPU 222 DC/DC/DC and CPU 222 AC/DC/Relay
CPU 224 Rel. 1.10 or greater CPU 224 DC/DC/DC and CPU 224 AC/DC/Relay
CPU 224XP Rel. 2.00 or greater CPU 224XP DC/DC/DC and CPU 224XP AC/DC/Relay
CPU 226 Rel. 1.00 or greater CPU 226 DC/DC/DC and CPU 226 AC/DC/Relay
The (CP 243--1) Ethernet module is delivered with a preset, unique worldwide MAC address that
cannot be changed.
Functions
The (CP 243--1) Ethernet module independently handles data traffic over the Industrial Ethernet.
- Communication is based on TCP/IP
- For communication between S7-200 CPUs and other S7 control systems or PCs via
Ethernet, communication services are available as Client and Server. Up to eight connects
can be operated.
- The implementation of PC applications is possible by integration of the S7-OPC Server
- The (CP 243--1) Ethernet module allows direct access of the S7-200 programming
software, STEP 7--Micro/WIN to S7-200 via Ethernet
Configuration
You can use the STEP 7--Micro/WIN Ethernet Wizard to configure the (CP 243 --1) Ethernet
module to connect an S7-200 PLC to an Ethernet network. The Ethernet wizard helps you define
the parameters for the (CP 243 --1) Ethernet module and then places the configuration instructions
in your project instruction folder. To start the Ethernet Wizard, select the Tools > Ethernet Wizard
menu command. The wizard uses the following information: IP Address, Subnet Mask, Gateway
Address, and communications connection type.
Connections
The (CP 243--1) Ethernet module has the
following connections. The connections are
located under the covers of the front doors.
- Terminal block for 24 VDC supply
voltage and ground connection
- 8-in RJ45 socket for Ethernet
