The IC697CPM790 is a 90-70 series Programmable Logic controller (PLC) CPU. The CPU is a single slot wide module designed for critical applications such as emergency shutdown systems, fire, gas and other applications. The CPU supports triple media redundancy (TMR) by integrating independent C programs to enable automated test programs.
The IC697CPM790 has 1 MB of battery backup memory, and user programs configured using the ladder diagram programming language can use up to 512KB. When configured in simplex mode, the CPU supports any combination of discrete input and output points up to 12K; Discrete input of 2048 votes and discrete output of 2048 votes. Similarly, the IC697CPM790 is capable of handling analog inputs and outputs up to 8K, and when run in simplex mode, can handle any combination of analog inputs and outputs, as well as 1024 voting analog inputs. It is equipped with a 2DX64 microprocessor with a clock speed of 80486 MHz. The CPU exhibits a relatively fast scan rate of 0.4 microseconds per Boolean function, suitable for critical applications.
The IC697CPM790 supports Triple modular redundancy (TMR) for system downtime. This TMR setup essentially consists of triple PLC racks, each with one (1) IC697CPM790 CPU, triple genius I/O bus, and triple input sensors and triple output loads.
The IC697CPM790 is equipped with one (1) 15-pin sub-D connector for communication with RS485 compatible devices. An RS-422/RS-485 to RS-232 converter with part number IC690ACC900 or an RS-232 to RS-422 microconverter with part number IC690ACC901 can be used to establish other forms of communication, such as connecting to a programming computer.
