Accessing Communications Areas by Specifying I/O Memory Addresses
AT specifications can be set for variables to individually specify the I/O memory addresses that are assigned
in the communications areas.
1
Setting Tag Sets (Network Configurator)
Specify the tag names in the PLC directly by using the I/O memory addresses that are assigned in the
communications areas. (Output tags are specified for the input connections to the Sensor and input tags
are specified for output connections to the PLC.)
Setting Examples
Output tag
Input tag
