GE FANUC IC693CPU364 , Single-Slot Central Processing Unit , Series 90-30 Processor Module

Product Description

The IC693CPU364 is a single-slot Central Processing Unit (from the GE Fanuc Series 90-30) with an embedded Ethernet cord and 1 built-in serial port. This unit is the “brains” of the PLC and is where most of the calculations take place. See specifications for this unit on IC693CPU364’s website page. A standard application for IC693CPU364 would be connecting a computer’s 9-pin serial port via IC693CBL316 to IC693CPU364’s standard Ethernet interface. It should be noted that IC693CPU364’s Ethernet interface is Ethernet Global Data (EGD). The benefit of this built in Ethernet interface is that you do not need to use a separate Ethernet module such as CMM321 with the unit. You can, in fact, save a PLC slot based on the built in nature of an Ethernet port on IC693CPU364.

The EGD also allows CPU364 to handle specialized parameters which HHP’s configuration mode is not able to do. Unlike CMM321, CPU364 does not require an external transceiver. CPU364 has a built in transceiver that can be connected to via the 10BASE-T port. CPU364 does offer some added functionality in the ability to add an external transceiver as well though. This can be done via the AAUI port which bypasses the internal transceiver. Another benefit of the built in Ethernet interface is that it can communicate without using the PLC backplane, creating faster communications speed than could be achieved with separate CPU and Ethernet modules. Some basic things to note regarding IC693CPU364 are that when using CPU364 you must connect to frame ground at the slot where it is installed. You can find a grounding wire on the unit for this very use.

CPU364 uses flash firmware standard with no EPROM, and no EEPROM. The current rating on IC693CPU364 is 1A and it uses GE Fanuc Fuse 44A725214–001. The maximum CPU capacity for CPU364 is 25 MHz utilizing the 80386EX processor. There are 2048 input points, 2048 output points. Register memory is configurable from 128 to 32640 words. CPU364 has firmware-based floating point math.

With Firmware Release 9.1 the EGD and configurable Name Resolution features were added to the CPU364.CPU364 has four LED lights, an Ethernet Restart button, a standard CPU keyswitch, three port connectors, and a shield ground connection tab. The four LED indicator lights pertain to the Ethernet interface and the PS port. Three of the lights are for Ethernet: EOK, LAN, and STAT, and 1 is for the PS port. The Ethernet Restart button has four uses:

• LED test
• Restart
• Restart and enter Software Load state
• Restart and enter Maintenance state

CPU364 has a Port 1, RS-232, AAUI port, and 10Base T port. These ports allow CPU364 to be connected to a terminal or terminal emulator (PORT 1), connect via IEEE 802.3 to an external Ethernet transceiver (AAUI), and to connect wo a 10Base T Ethernet network.The firmware on CPU364 is, as stated above, stored in Flash memory and loaded via the serial port connector. This is done using a personal computer with loader and software. Similarly, the Ethernet Interface firmware is stored in Flash memory and loaded through the Port 1 connector in the same manner.

The IC693CPU364 is equipped with 8 baseplates, which consist of a single CPU baseplate and 7 baseplates that can either serve as expansion or remote baseplates. It uses an 80386EX processor running at 25 MHz and requires a load of 1.51 amps from +5 VDC power supply. It also has a slow acting, replaceable Ethernet fuse of size 2.69 x 2.69 x 6.1 mm, with a voltage of 125V and a current of 1 A. The module operates with an ambient temperature ranging from 0 to 60 degrees Celsius (or 32 to 140 degrees Fahrenheit). It has a typical scan rate of 0.22 milliseconds per 1K of logic or Boolean contacts.

The IC693CPU364 has up to 240K bytes of program memory available for the user. Please note: the actual size of available user program memory depends on the amounts configured for %R, %AI, and %AQ configurable word memory types as outlined below. Its register memory (%R) is configurable in increments of 128 words, from 128 to 16,384 words with Logicmaster and from 128 to 32,640 words with Control version 2.2. It comes installed with a discrete global memory (%G) of 1280 bits, internal coils (%M) of 4096 bits, output (temporary) coils (%T) of 256 bits, and system status references (%S) of 128 bits (with %S, %SA, %SB, %SC having 32 bits each). Analog inputs (%AI) and outputs (%AQ) are both configurable in increments of 128 words, from 128 to 16,384 words with Logicmaster and from 128 to 32,640 words with Control version 2.2. Discrete input (%I) and output (%Q) outputs are 2,048 each. It has 28 words (%SR) system registers which are used for reference table viewing only and cannot be referenced in user logic program. It supports RAM and flash memory types and has a firmware based floating point math support.

It has shift registers, override, battery-backed clock, with interrupts that support the periodic subroutine feature, and over 2000 timers/counters. It only has one built-in serial port which uses a connector on the PLC power supply. The port supports SNP/SNP-X slave protocols. The module has PCM/CCM compatibility; however, in order to support SNP/SNP-x master, CCM, or RTU slave support, it requires a CMM module. It also requires a PCM module to support RTU master. It has an internal AAUI or 10BASE-T Ethernet (the AAUI requires external transceiver while the 10BASE-T is direct). It also has an additional external Ethernet that supports Ethernet option modules. The installed Local Area Network (LAN) requires option modules for Genius, Profibus, and FIP. Earlier modules may have the LED labeled “SNP” instead of “PS PORT.” Otherwise, these modules are identical.
