Cyclic transmission
This function allows periodic data communication among stations on the network using link devices.
Function
Communications using RX, RY, RWr, and
RWw
Communications using LB and LW
Access to devices Link refresh
and link devices
Direct access to link
devices
Cyclic data integrity assurance
Communication cycle coexistence
Interlink transmission
I/O data hold/clear Output mode upon
setting when data CPU error
link stops
Output hold/clear
setting during CPU
STOP

station setting
Transient transmission
This function is used for communication at any timing. There are the following three types of transient transmission functions.
Function
Communications using a dedicated
instruction
Communications using the SLMP
Communications using the engineering
tool
Description
Communicates I/O data in units of bits and words between the master station
and slave stations.
Communicates data between controllers of the master station and local
station.
Automatically transfers data between link devices of RJ71GN11-T2 and
devices of CPU modules.
Reads or writes directly from the program to link devices of RJ71GN11-T2.
Assures the cyclic data integrity in units of 32 bits or station-based units.
When slave stations with different communication cycles coexist in the
network, this function enables communication in different communication
cycles according to each slave station.
Transfers data in the link devices of the master station to another network
module on a relay station.
Select whether to hold or clear the output data when the CPU module on the
sending side is in stop error.
Select whether to hold or clear the output data when the status of the CPU
module on the sending side changes from RUN to STOP.
Select whether to hold or clear input data on the receiving side when the
sending side disconnects.
Description
Uses dedicated instructions to read/write data from the master station to
devices in a CPU module of the local station or the buffer memory of a
remote station. ( MELSEC iQ-R Programming Manual (Module
Dedicated Instructions))
Reads/writes data via SLMP from a personal computer, HMI (Human
Machine Interface), or other external device to devices in a CPU module of
the master station or local station or to the buffer memory of a remote station.
( SLMP Reference Manual)
Accesses and communicates with stations on different networks with the
engineering tool, allowing seamless communication.
