Functions The CPU 782 is a single slot programmable controller CPU which 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 the 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 configuration data can be locked through software passwords or manually by the memory protect keyswitch. When the key is in the protected position, program and configuration data cn only be changed by a programmer connected parallel only(i.e., via the Bus Transmitter module).

Typical PLC System Diagram 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 toggle switch in the STOP position. Put keyswitch in Memory Protection OFF position. Make sure rack power is off. Install in slot 1 of rack 0. (See Figure 1) Turn on 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 keyswitch 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 non-volatile flash memory. The battery which supports the CMOS RAM memory is located on the main CPU board. (See Figure 2). Installation of an expansion memory board on the CPU will require initialization of the CPU with the programmer (See Reference 2). 3 16 MHz, 32-Bit, Expandable, Floating Point Central Processing Unit GFK-0767D PLC CPUs August 1997 Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F 16-3 MEMORY PROTECT a45155 OPEN REPLACEMENT BATTERY CONNECTOR EXPANSION MEMORY BOARD IC697MEM731 IC697MEM732 IC697MEM733 IC697MEM735 CPU 782 CURRENTLY INSTALLED BATTERY CONNECTOR MEMORY PROTECT KEY SWITCH MODULE IC697CPU781 LABEL 44A726758-129R01 SERIAL PORT USE THIS MODULE IN SLOT 1 ONLY CPU 782 OFF ON TOP MODULE OK RUN OUTPUTS ENABLED ON = OK, ENABLED, PROTECTED FRONT RUN WITH OUTPUTS ENABLED RUN WITH OUTPUTS DISABLED STOP KEY POSITION MODULE FUNCTION 16MHz 32 BIT CENTRAL PROCESSING UNIT BATTERY CONNECTORS INSTALL NEW BATTERY BEFORE UNPLUGGING OLD BATTERY.

CPU 782 - Location of Major Features 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), see Figure 1. Consult Reference 2 for a description of programming functions. Serial Port The 15-pin D-connector provides the connection to an RS-485 compatible serial port as shown in Figure 3. This port provides a serial connection to an IC647 communications interface board installed in the programming computer. The serial connection can also be made from the Standard Serial COM port on the CPU to the serial port on the programming computer, or other serial device, through the RS-422/RS-485 to RS-232 Converter (IC690ACC900) or RS-232 to RS-422 Miniconverter (IC690ACC901). This connection can be made with available cables or you may build cables to fit the needs of your particular application. For more information on serial communications, see Reference 3.

This can be either the Ethernet Controller, IC697CMM741, or Ethernet Interface (Type 2), IC697CMM742. Before connecting your programmer and PLC to the Ethernet TCP/IP network you must set the IP address in the Ethernet Interface. After setting the IP address, connect the PLC and the programmer running Windows software to the Ethernet Interface. For more detailed information on Ethernet TCP/IP, refer to the TCP/IP Ethernet Communications (Type 2) User s Manual, and the Windows programming manual, GFK-1295. Configuration The IC697 CPU and I/O system is configured with MS-DOS or Windows based programming software. There are no DIP switches or jumpers used to configure the system. The CPU verifies the actual module and rack configuration at power-up and periodically during operation. The actual configuration must be the same as the programmed configuration. Deviations are reported to the CPU alarm processor function for configured fault response. Consult Reference 1 for a description of configuration functions. Batteries A lithium battery (IC697ACC701) is installed as shown in Figure 2. This battery maintains program and data memory when power is removed and operates the calendar clock. Be sure to install the new battery before removing the old battery. If during power-up diagnostics a low battery is detected the Module OK LED (top) will not stay on. Specific indication of a low battery state is detailed in Reference 2. Removing a Module The following instructions should be followed when removing a module from its slot in a rack. Grasp the board firmly at the top and bottom of the board cover with your thumbs on the front of the cover and your fingers on the plastic clips on the back of the cover. Squeeze the rack clips on the back of the cover with your fingers to disengage the clip from the rack rail and pull the board firmly to remove it from the backplane connector. Slide the board along the card guide and remove it from the rack. Table 1.
