IC697CPU782 Central Processing Unit

Functions:

IC697CPU782 is a single-slot programmable controller CPU that allows floating-point calculations. The CPU782 is programmed and configured by MS-DOS or Windows-based programming software to perform real-time control of machines, processes, and material handling systems.

The CPU 782 communicates with I/O and smart option modules over a rack-mounted backplane (IC697CHS750, 782, 783, 790, 791) by way of the VME C.1 Standard format.

Supported option modules include all IC697 LAN interface modules, several Coprocessor modules, Bus Controller for IC660/IC661 I/O, Communications modules, and all of the IC697 family of discrete and analog I/O modules.

Program and data memory for the CPU 782 is available by the attachment of an expansion memory board with either 128, 256, or 512 KBytes of battery-backed CMOS RAM, or 256 KBytes with w/256 KBytes of Non-volatile flash.

Operation of this module may be controlled by the three-position RUN/STOP switch or remotely by an attached programmer and programming software. Program and configuration data can be locked through software passwords or manually by the memory protect key switch. When the key is in the protected position, program and configuration data can only be changed by a programmer connected d parallel only(i.e., via the Bus Transmitter module). The status of the CPU is indicated by the four green LEDs on the front of the module.

Installation:

It is the responsibility of the OEM, system integrator, or end user to properly install the PLC equipment for safe and reliable operation. Product manuals provide detailed information about installation, startup, and proper use of the PLC equipment. The installation manual, shipped with your PLC programming software, describes how to properly install the equipment. If the PLC installation must comply with supported standards, such as FCC or CE Directives, please refer to the Installation Requirements for Conformance to Standards, shipped with the PLC programming software, for additional guidelines.

Installation should not be attempted without referring to the applicable hardware installation manual.

Align the expansion memory and CPU connectors.

Align the captive screws on the memory board with the standoffs already installed on the CPU.

Push the memory board onto the CPU connector, ensuring that the mating screws remain aligned with their respective standoff.

Screw each memory board screw into the standoffs with a #1 Phillips screwdriver, and tighten.

Connect the battery to either of the battery connectors on the module.

Put the toggle switch in the STOP position.

Put the keyswitch in the Memory Protection OFF position.

Make sure the rack power is off.

Install in slot 1 of rack 0.

Turn on the power.

The module should power up and blink the top LED. When the diagnostics have completed successfully, the top LED stays on and the second and third LEDs are off.

The fourth LED is off if the key switch is in the OFF position. The CPU is now ready to be programmed. After the program has been verified, the toggle switch may be moved to the appropriate operation mode position. The LEDs indicate the position of the toggle switch, memory protection status, and the state of the program.

Expansion Memory:

The CPU 781 must have a CMOS expansion memory board. Expansion memory boards are available with 128 KBytes, 256 KBytes, 512 KBytes, and 256 KBytes with 256 KBytes s non-volatile flash memory. The battery that supports the CMOS RAM is located on the main CPU board.

Installation of an expansion memory board on the CPU will require initialization of the CPU with the programmer.

Programmer Connection, Parallel:

The programmer connects to the top port on the bus transmitter (IC697BEM713) system interface module for a parallel interface (MS-DOS programmer only)
