MELSEC iQ-R Simple Motion Module User's Manual (Network)
Cyclic transmission
Function
Fixed-cycle communication
Communications with Communications using
other stations RX and RY
Communications using
RWr and RWw
Access to devices and Link refresh
link devices
Direct access to link
devices
*1
Cyclic data integrity assurance
Interlink transmission
Mode selection for cyclic transmission
Input status setting for data link faulty station
Output status setting for CPU STOP
Output status setting for CPU stop error
Cyclic transmission stop and restart
*1 When the software version of the Simple Motion module is "Ver.01":
The set parameter is ignored in the Simple Motion module and operate as "Disable" in station-based units. Assure data using interlock
programs as required.
When the software version of the Simple Motion module is "Ver.02" or later:
To enable data assurance in an asynchronous station, read/write data by direct access in the inter-module synchronous interrupt
program (I44) without using a link refresh.
*2 When the software version of the Simple Motion module is "Ver.01":
The set parameter is ignored in the Simple Motion module and operate as "Hold". Add "Data link status of each station" (SW00B0 to
SW00B7) to an interlock of the program as required.
Transient transmission
Function
Communications within the same network
Communications with different networks
Dedicated instruction
RAS
Function
Slave station disconnection (only for
asynchronized stations)
Automatic return
Description
The communication cycle of the Simple Motion module is fixed cycle. Communicates with slave modules
in a cycle set in the inter-module synchronization cycle setting.
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 Simple Motion module and the device of the
CPU module
Directly accesses the link devices of the Simple Motion module from a 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 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.
*2
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 Simple
Motion 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 Simple Motion 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 Programming Manual (CPU Module
Instructions, Standard Functions/Function Blocks))
Description
Disconnects only the slave station where an error occurs, and continues the data link with the stations
that are operating normally. In a line topology, all stations connected after the faulty station are
disconnected.
Automatically returns the station disconnected from the network due to a data link error to the network
when it recovers and restarts data link.
