Description
Allows each station to write data to its own send range of a link device (LB,
LW) to send them to all other stations on the network.
Exchanges data between the I/O master station that controls LX and LY and
another station on a one-to-one (1:1) basis.
Automatically transfers data between the link devices (LB, LW, LX, LY, SB,
SW) of the CC-Link IE Controller Network-equipped module and devices of
the CPU module, or between the link devices (SB, SW) of the CC-Link IE
Controller Network-equipped module and the module labels of the CPU
module.
Directly accesses the link devices of the CC-Link IE Controller Network-
equipped module from the program.
Assures the cyclic data integrity in units of 32 bits or station-based units.
Transfers the link device (LB, LW) data of a CC-Link IE Controller Network-
equipped module to another network module at a relay station.
Keeps the link scan time constant using the following methods.
• Specification of the number of transient transmissions: Specifies the
number of transient transmissions within one link scan.
• Constant link scan: Specifies the link scan time.
Divides the stations within the network into groups and specifies the
stations that share cyclic data (shared group). This setting allows cyclic data
to be shared among the stations having the same shared group number
and not to be received from those having a different shared group number.
Stations having no shared group number assigned will share cyclic data
with all stations.
Sets a CC-Link IE Controller Network-equipped module to the extended
mode using an engineering tool so that the number of send points per
station will be extended to a maximum of 32K points for the link relay (LB)
and 128K points for the link register (LW) in one module.
Stops the cyclic transmission during debugging and other operations. (Data
reception from other stations 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 Programming
Manual (Module Dedicated Instructions))
Sends data to all stations of the same transient transmission group number by
dividing the transient transmission target stations into groups.
