The Series 90* -30 CPU374 PLUS provides a built-in enhanced Ethernet interface that provides TCP/IP communications with: ▪ Series 90, PACSystems, and VersaMax PLCs ▪ Host computers running the Host Communications Toolkit or CIMPLICITY software ▪ Computers running the TCP/IP version of the programming software CPU Features ▪ High speed Boolean and non-Boolean processing provided by a 586-class 133MHz processor ▪ Two Ethernet ports: 10/100 Mbytes (one IP address) with a built-in, auto-sensing Ethernet switch ▪ Support for EZ Store Device allows you to download a program without a PC ▪ 240KB of user memory Key Ethernet Features ▪ Full PLC programming and configuration services ▪ Periodic data exchange using Ethernet Global Data (EGD) and EGD commands to read and write PLC and EGD exchange memory over the network ▪ TCP/IP communication services using SRTP ▪ Support for SRTP Client (Channels) ▪ Modbus/TCP Server, supporting Modbus Conformance classes 0, 1, and 2. ▪ Modbus/TCP Client, supporting Modbus Conformance classes 0, 1, and Function Codes 15, 22, 23, and 24 for Conformance class 2. ▪ Remote PLC monitoring from a web browser ▪ Comprehensive station management and diagnostic tools

Supported Features

Some features that are shown in the Machine Edition configuration for the CPU374 PLUS are not supported on the older versions. This includes features like Modbus. While the configuration remains backward compatible with older CPU374s, new features are not allowed on older versions. Thus the latest version should be used when the newer features are desired.

The expected life of a standard Series 90-30 3-volt lithium battery used to back up a CPU374 is 1.2 months when used continuously. If a longer battery backup period is required, the external battery module (IC693ACC302) is available. The extended battery module provides a nominal battery backup period of 15 months for the CPU374. See GFK-2124 for additional information.

When storing reference data to flash or the EZ Program Store Device, overrides are not stored. This means that after the reference data is read back from flash or the EZ Program Store Device and subsequently the PLC is put into Run Mode, the logic may execute differently. Therefore, overrides should not be used if reference data is stored to flash or to the EZ Program Store Device. If overrides are used, particular care should be taken to prevent loading reference data from flash at power up. If this precaution is not observed, unexpected operation may occur upon power cycle.

When writing very large programs to flash memory, you may need to increase the request timeout value in the programming software to avoid receiving a request timeout message. An upper bound of 25 seconds is typically satisfactory. For further details, see the “Ethernet Operational Notes” item “Store of Program or Reference Tables to Flash may Cause Loss of Ethernet Communications” on page 11.
