GFK-1490C
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.
