Slave Module Parameter Read/Write

In the AnyWireASLINK transmission, in addition to I/O data, parameter information of a slave module and the
AnyWireASLINK system is sent and received between the RJ51AW12AL and the slave module.
Use this function to check or change parameter information of a slave module.
For details on the parameter information to be communicated, refer to the following.
• Page 104 Parameter access setting
• Page 104 Parameter access target module ID specification
• Page 105 Parameter storage location memory number
• Page 107 Parameter storage area
Parameter reading and writing methods
There are four methods as follows to read or write the parameter information from or to a slave module.

Parameter access
Parameter batch read
Parameter batch write
The following shows the readable/writable parameters.

*1 The device parameter name differs depending on the slave module to be used.
Parameter access, parameter batch read, or parameter batch write does not affect the AnyWireASLINK
transmission cycle time.
Automatic update
No special operation is required because data are automatically updated. To check the parameter information, refer to the
corresponding buffer memory address.
Description
The status details and the sensing level of all slave modules are read at regular intervals. (Setting values are
excluded.)
All the parameter values of the slave modules are read or written individually in accordance with the setting of
reading or writing and the target slave module.
All the parameter values of all slave modules are read out into the buffer memory of the RJ51AW12AL.
Values set in the buffer memory of the RJ51AW12AL are written to all the parameter of all slave modules.
