【英文介紹】
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 separate C programs to enable automated test routines.
The IC697CPM790 has 1 MB of battery backup memory and up to 512KB is available for user programs configured using the ladder diagram programming language. When configured in simplex mode, this 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, can handle any combination of analog inputs and outputs when run in simplex mode, and has 1024 voting analog inputs. It is equipped with a 2DX64 microprocessor with a clock speed of 80486 MHz. The CPU has a relatively fast scan rate of 0.4 microseconds per Boolean function, which is 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. Other forms of communication, such as connection to a programmed computer, can be established using RS-422/RS-485 to RS-232 converters with part number IC690ACC900 or RS-232 to RS-422 microconverters with part number IC690ACC901.
