Product:General Electric IC693CPU364 CPU model

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.
