Installing an IC693 CPU374 with Embedded TCP/IP Ethernet Interface

The CPU374 with Embedded Ethernet Interface is mounted on the Series 90-30 PLC baseplate. It is connected to an Ethernet network via either or both of its auto-sensing 10Base-T/ 100Base TX ports.

ADDRESSLABEL LABEL

The Series 90-30 CPU374 has several user-accessible elements (only the Ethernet Interface’s applicable elements are discussed here.)

Three Ethernet LEDs are located at the top left of the module. The Ethernet Restart pushbutton is located below the LEDs. The RS-232 serial port with the RJ-11 connector (similar to a modular telephone connector) is used to connect to Station Manager. Below the serial port are twoRJ-45 ports, either or both of which can be used to connect to the Ethernet network..

The default station address (MAC address) label is located on the outside of the module.

LEDs

There are eight LEDs on the CPU374. Four of these LEDs: EOK, LAN, STAT, and PS PORT give module status information. Four LEDS are associated with the two RJ-45 ports. The PS (Power Supply) PORT LED is not Ethernet related; it indicates the presence of serial traffic through the serial port of the PLC’s power supply. Each of the three Ethernet LEDs (EOK, LAN, and STAT) can be ON, OFF, BLINKING slow, or BLINKING fast. They indicate the state of the Ethernet Interface, traffic at the Ethernet Interface (LAN LED), and that an exception event has occurred.
