3.3 Function List of CC-Link IE Field Network
Description
Communicates I/O data in units of bits between the master station and other
stations.
Communicates I/O data in units of words between the master station and other
stations.
Automatically transfers data between the link device of the master/local
module and the device of the CPU module
Directly accesses the link devices of the master/local module from the
program.
Assures the cyclic data integrity in units of 32 bits or station-based units.
Transfers data in the link devices of the master station or submaster station to
another network module on a relay station.
Selects the mode for optimizing the performance of cyclic transmission based
on the cyclic transmission and transient transmission frequency. The mode is
selected from "Normal", "High-Speed", or "High-Speed Remote Net".
Selects whether link scan is set to asynchronous or synchronous with the
sequence scan of the CPU module.
Keeps the link scan time constant by setting the constant link scan time.
Selects whether input data from another station where a data link error occurs
is cleared or held.
Selects whether cyclic data output is held or cleared when the CPU module
mounted with a master/local module is set to STOP.
Selects whether cyclic transmission output is held or cleared when a stop error
occurs in the CPU module which a master/local module is mounted with.
Stops the cyclic transmission during debugging and other operations. (Data
reception from a slave station and data sending from the own station are
stopped.) Also, the stopped cyclic transmission is restarted. Transient
transmission does not stop.
Description
Performs the transient transmission to other stations using dedicated
instructions and the engineering tool.
Performs the transient transmission seamlessly to stations on different
networks using dedicated instructions and the engineering tool.
An instruction for using functions of modules. ( MELSEC iQ-R
