Security Function; Individual Identification Information Read Function - Mitsubishi Electric MELSEC iQ-R C User Manual

Security Function

This function prevents assets stored in a C intelligent function module from being stolen, falsified, operated incorrectly, and
executed improperly due to unauthorized access from a third party.
The security function is one of the methods for preventing unauthorized access (such as program or data
corruption) from an external device. However, this function does not prevent unauthorized access completely.
Incorporate measures other than this function if the programmable controller system's safety must be
maintained against unauthorized access from an external device. Mitsubishi Electric Corporation cannot be
held responsible for any system problems that may occur from unauthorized access.
Examples of measures for unauthorized access are shown below.
• Install a firewall.
• Install a personal computer as a relay station, and control the relay of send/receive data with an application
program.
• Install an external device for which the access rights can be controlled as a relay station. (For details on the
external devices for which access rights can be controlled, consult the network provider or equipment
dealer.)

Individual identification information read function

The individual identification information of a C intelligent function module can be read with the C intelligent function module
dedicated function (CITL_GetIDInfo). By implementing an activation function with a user program, a user program, which
does not run in C intelligent function modules with other individual identification information, can be created.
For C intelligent function module dedicated functions, refer to the following manual.
