GE IC697CPM790 64 MHz CPU with calculation capability using a 32-bit floating point

Product information GE IC697CPM790 :

The IC697CPM790 is a Series 90-70 Programmable Logic Controller (PLC) CPU. This CPU is a single slot wide module that is specifically used for critical applications such as Emergency shutdown systems, fire, gas and other applications. This CPU supports Triple Media Redundancy (TMR) by incorporating Standalone C program for enabling autotest routines as well.

The IC697CPM790 features 1 MB of battery-backed memory with up to 512KB available for utilization by the user program configured using ladder diagram programming language. This CPU supports up to 12K discrete input and output points, of any combination, when configured in simplex mode; 2048 voted discrete inputs and 2048 voted discrete outputs. Similarly, the IC697CPM790 is capable of handling up to 8K analog inputs and outputs, of any combination when operated in simplex mode and 1024 voted analog inputs. It is equipped with an 80486DX2 microprocessor with clock speed of 64 MHz. This CPU exhibits a relatively fast scan rate of 0.4 microseconds per boolean function, suitable for use in critical applications.

The IC697CPM790 supports Triple Modular Redundancy (TMR), utilized to allow the system without the chance of downtime. This TMR set-up is basically comprised of Triple PLC Racks with each rack having One (1) IC697CPM790 CPU, Triple Genius I/O Busses, as well as Triple input sensors and Triple output loads.

The IC697CPM790 comes with One (1) 15-pin sub-D connector allowing communication with RS485 compatible devices. Other forms of communication such as connection to a programming computer may be established with the use of RS-422/RS-485 to RS-232 Converter with part number IC690ACC900 or RS-232 to RS-422 Miniconverter with part number IC690ACC901.

The IC697CPM790 programmable controller CPU is also suitable for critical industrial and commercial safety-related applications such as fire and gas-related applications and ESD or Emergency Shutdown systems. It is programmed using the Windows or MS-DOS software and able to communicate with the I/O modules and the smart option modules in the same PLC system that it is installed in through the rack-mounted backplane. The IC697CPM790 programmable controller CPU cannot operate unless a Standalone C program is included as part of the loaded application program for the CPU.

No Cold Junction Compensation:
This is used for millivolt inputs or if cold junction is maintained at 0 degrees C.
Remote Cold Junction Compensation: With this option, cold junction is measured externally and provided to the module from the application, via the module’s analog output (word output) data. If the module has multiple thermocouples that are configured for remote compensation, the same compensation value must be used by each.

Fixed Cold Junction Compensation: This option uses a fixed compensation value which is provided as part of the module configuration.

Local Cold Junction Compensation: The best way to provide local compensation is with an Interposing Thermocouple Carrier, which has a built-in thermistor. Using an Interposing Carrier allows the thermocouple connections to be placed farther away from the I/O modules in the system, which helps shield thermocouple connections from module heat.
