Slave Module Parameter Read/Write
In AnyWireASLINK, parameter information of a slave module and the AnyWireASLINK system in addition to I/O information
are sent and received between the FX5-ASL-M and a 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 80 Parameter access setting
• Page 80 Parameter access target module ID specification
• Page 81 Parameter storage location memory number
• Page 82 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.

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

Status details
Sensing level
*1 The device parameter name differs depending on the slave module to be used.
Even when the parameter access, parameter batch read, or parameter batch write is executed, the bit
transmission speed of AnyWireASLINK is not reduced.
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 current status of all slave modules and the current values of the sensors 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 FX5-ASL-M.
Values set in the buffer memory of the FX5-ASL-M are written to all the parameter of all slave modules.
