Product: IC693CPU364 CPU Module with Ethernet Interface

IC693CPU364-AC with Firmware Release 9.10

Introduction

This document contains information that is not available in any other publication; therefore, we recommend you save it for future reference. This document discusses the features of the CPU module IC693CPU364. This module provides two functions in one module: (1) it serves as a High Performance CPU, and (2) it provides Ethernet communications capability with its embedded (built-in) Ethernet Interface. This release provides Ethernet Global Data (EGD) and configurable Name Resolution for the 364 module.

CPU364 Feature Highlights (Release 9.10)

CPU Features

·Ethernet Global Data and Name Resolution are supported in this release. Version 2.2 or later of the Windowsâ based PLC programming software or version 1.0 or later of the VersaPro Windows-based programming software is required for configuration of these features. For details, refer to the software online help, the TCP/IP Ethernet Communications for the IC69* User's Manual, and the TCP/IP Ethernet Communications for the IC69* Station Manager's Manual.

The following features were introduced in release 9.00.

·Software Floating-Point. The CPU364 supports all of the floating-point function blocks that are currently supported by the CPU352. They are implemented in firmware using floating point emulation in the CPU364. These Floating-Point math function blocks are described in the IC693 PLC Reference Manual.

·User memory totals 240K bytes. %R, %AI, and %AQ references are configurable up to 16K of %R, 8K of %AI and 8K of %AQ memory using the MS-DOSâ PLC programming software, version 9.02 or later. These three references are configurable up to 32K in release 1.0 of the VersaPro software and release 2.2 of the Windows-based PLC programming software. Configuration instructions for this feature are described in the MS-DOS IC693 Programming Software User’s Manual, and is included in on-line help in both of the Windows PLC Programming Software packages.

·Sequential Event Recorder. The Sequential Event Recorder can be used to record up to 1024 samples of 32 individual discrete (bit) references. This function block is described in the IC693 PLC Reference Manual and in online help in the Windows PLC Programming Software.

·Break-free SNP. The SNP protocol no longer requires a break to operate. This allows SNP to work over a wider variety of modems.

Ethernet Features

·The CPU364 supports connection to an Ethernet network via either (but not both) of two built-in Ethernet network ports:

1.AAUI: Capability is provided for connection to various types of Ethernet LANs via an external AAUI transceiver connected to the AAUI port. The IC649AEA103 AAUI transceiver may be used, or the user may supply a different model that meets AAUI standards.

2.10Base T: The CPU364 provides direct connection to a 10BaseT (twisted pair) Ethernet LAN from its 10BaseT port.

Important Product Information

GFK-1490C

The CPU364 provides network communications using SRTP (Service Request Transfer Protocol) over standard TCP/IP (Transmission Control Protocol / Internet Protocol) on an Ethernet Local Area Network (LAN). The CPU364 supports communications with other IC693 PLCs and/or IC697 PLCs equipped with TCP/IP Ethernet Interfaces, and with MS-DOS TCP/IP programming software and applications which use the TCP/IP Host Communications Toolkit (HCT) Software.

Hardware Identification

The following table shows the revision level of the circuit boards used in this version (-AC) of the IC693CPU364. If you wish to upgrade an existing CPU364 to firmware version 9.10, you may purchase the kit identified in the following table. All previous versions are capable of being upgraded.

Functional Compatibility

The Windows PLC Programming Software version 2.00 or later must be used to take advantage of C programming or Sequential Function Chart (SFC) subroutines.

Version 4.00 or later of the C toolkit must be used for C programming.

The MS-DOS PLC Programming Software Version 9.02 or later must be used to take advantage of the new features introduced in firmware release 9.00. These new features are listed in the section “New Features and Functionality of Firmware Release 9.00.” Note that the CPU363 can be configured with the MS-DOS PLC Programming Software Version 9.01, but only features prior to firmware release 9.00 are supported in that software version.

The Windows PLC Programming Software version 2.20 or later or VersaPro version 1.00 or later is required for configuration of the Ethernet Global Data and configurable Name Resolution features of the 364 PLC.

Operating Notes

User Flash Contents

User information, consisting of program, configuration, CPU ID (used for SNP communications), and status tables in RAM memory, will automatically be cleared if the CPU firmware in flash memory is changed. You will need to restore these if upgrading firmware. A recommended procedure is to first back up your user information from RAM memory to Flash memory. Then write your new firmware to Flash memory (firmware is stored in a different location in Flash memory than that used for storing user information such as program, configuration, etc.). Finally, write your user information back out of Flash into RAM memory. As an alternative, your user information (program, configuration, etc.) can be restored from a computer-based backup program folder using your PLC programming software. The SNP ID must be set separately, using the programming software or the Hand-Held Programmer (HHP).

Firmware Upgrade Procedure
The Model 364 CPU operating firmware is stored in flash memory. The firmware upgrade is provided on a diskette and must be serially downloaded from a Personal Computer. An IBM AT personal computer or better PC with a minimum 640K of RAM, one 3.5” diskette drive, MS-DOS version 3.3 or later (or Windows 95 or later), and one RS-232 serial port is required. In addition, two serial cables are required. The following serial cable kit is available:
IC690ACC901, Mini Converter Kit with cable (RS-232/RS-485) This cable can be assembled from the following parts: IC690ACC900, RS-232 to RS-485/422 Converter Unit IC693CBL303, 15 Pin RS-485 Serial Cable
IC690CBL705, 25 Pin RS-232 Serial Cable or IC690CBL702, 9 Pin RS-232 Serial Cable (Only one of these cables is required. Selection depends on PC Serial Port Connector.)

An additional diskette and an additional cable, IC693CBL316, is required to serially download the Ethernet firmware from the PC to the CPU.

Option Module Revision Requirements

All IC693 Ethernet Interface (IC693CMM321) modules used with this CPU should be updated to IC693CMM321 firmware release 1.10 or later. This is also a requirement of the TCP/IP Ethernet version of the MS-DOS programming software.

FBC version 3 or later is required for this CPU.

Writing Flash Using a Serial Programmer

When writing very large programs to flash memory, it may be necessary to increase the Windows programming software request timeout value to avoid receiving a request timeout message. An upper bound of 25 seconds is typically satisfactory. For further details, see the item “Store of Program or Reference Tables to Flash may Cause Loss of Ethernet Communications” later in this section.

Power Supply Requirements

The CPU364 requires one of the three following PLC power supplies: IC693PWR321 (Rev. K or later), IC693PWR322, IC693PWR330, or IC693PWR331. Power consumption of the CPU364 and its supporting devices are listed below:

CPU364 requires 1.1A @ +5VDC (= 5.5 Watts).

If used, the external AAUI transceiver will require a maximum of 400 mA, or 2.0 Watts (limited by the AAUI standard). Consult the transceiver documentation to obtain its exact power requirements. The IC649AEA103 transceiver requires 380 mA at 5 VDC (=1.9 Watts).

If used, the converter in the IC690ACC901 serial cable assembly requires 100 mA at 5 VDC (=0.5 Watts).

If used, the IC690ACC900 RS-422/RS-485 to RS-232 converter requires 170 mA at 5 VDC (=0.85 Watts).

Unreliable AAUI 10Base2 Ethernet Transceiver (IC649AEA101A)

The external AAUI 10Base2 Ethernet transceiver, available as catalog number IC649AEA101A, has been discovered to operate unreliably under some conditions. This part is no longer offered. Instead, please use catalog number IC649AEA103.

Configuration via Serial Port is Required Before Using Ethernet Communications

The Ethernet Interface within the CPU module cannot operate on a network until a valid IP address is configured. The necessary Ethernet addressing information must be configured prior to actual network operation. Two methods are available:

1.Perform the initial configuration using a PLC Programmer connected through the PLC power supply serial port.
