Product Description

The GE Fanuc IC693CPU372 is a TCP/IP Ethernet Communications module. Like the CPU374 model, this module is designed to work with the Series 90-30 system. The IC693CPU372 Plus enables TCP/IP communications with a range of devices and controllers through its built-in enhanced Ethernet interface. This includes all Series 90, PACSystems, and VersaMax PLCs as well as host computers running the Host Communications Toolkit or CIMPLICITY software. It can also communicate with computers running the TCP/IP version of the programming software. Its Ethernet processor speed is 200 MHz. This Ethernet interface also has SRTP server capability. This enables it to respond to requests from devices such as PLC programming software, a Host computer that is running an SRTP application, or else another PLC acting as a client.

The embedded Ethernet interface in this module can be joined by a maximum of three Series 90-30 Ethernet Modules – all can be installed together in the Series 90-30 PLC backplane. The CPU372 PLUS has a number of Ethernet features that make it a flexible and powerful component, such as full PLC programming and configuration services and the ability to let users operate it through remote PLC monitoring from a web browser. The interface has two auto-sensing 10Base T / 100Base TX RJ-45 shielded twisted pair Ethernet ports. These allow the user to connect it to either a 100BaseTX IEEE 802.3 network or a 10BaseT network. Each of the two ports automatically sense the speed, duplex mode and cable attached to it with no user intervention required. On the front panel there is an ON/OFF switch, eight LEDs, the Ethernet Restart button, two Ethernet port connectors and a connector to enable the Station Manager function.
