IC697MEM719 扩展存储模块 英文介绍
IC697MEM719 Extended Storage Module
IC697MEM719 is an extended storage module of GE Fanuc 90-70 series PLC, used to provide larger program and data storage space for the system. It is similar to MEM713/MEM715/MEM717, both designed for memory expansion in PLC systems, but with differences in capacity and usage.
main purpose
Expand program memory capacity
When the built-in storage of PLC cannot meet the requirements of large-scale programs, MEM719 provides additional space for storing more complex control logic.
Save data and system information
In addition to program code, it can also be used to retain information such as variables, data blocks, system settings, etc.
Power off hold function
Internally, non-volatile storage (such as CMOS combined with power supply) is used to ensure data preservation even after power failure.
Technical Features
Good compatibility
Seamless connection with 90-70 series CPU modules, it can be used as a standard expansion unit.
Large expansion capacity
Compared to some early expansion storage modules, MEM719 has a larger available storage capacity and is suitable for more complex control applications.
Stability and anti-interference
Industrial grade design with excellent noise resistance, vibration resistance, and high stability.
Modular structure
Plug in module installation, convenient for on-site configuration and maintenance.
Support diagnostic function
Can cooperate with the system diagnostic mechanism to provide monitoring and alarm of memory expansion status.
Applicable scenarios
Large scale automation system control program
Industrial sites with complex program logic and numerous variables
Applications that require extended storage to support the preservation of historical data or more data structures
System upgrade project requiring an increase in PLC memory capacity
summary
IC697MEM719 is an important module used to expand storage capacity in the GE Fanuc 90-70 PLC system. By increasing storage space, it can support larger scale programs and more data, enabling PLC control systems to have stronger processing capabilities and higher flexibility.
