4.14 Safety Information Monitoring Function
To store information including the I/Os, settings, and error codes of a safety extension module to the buffer memory.
The safety information can be referenced by user programs and built-in functions (such as Web server) of a CPU module or
the monitoring screen of GX Works3.
Operation
This function stores information including the I/Os, settings, and error codes of a safety extension module to a buffer memory
of a safety main module.
Not only the information of a safety main module, but also the information of a safety extension module are stored in the buffer
memory.
