Reading and Writing Parameters

In the AnyWireASLINK system, the parameter information of a slave module and the AnyWireASLINK system in
addition to I/O information are sent and received between the master module 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 sent and received, refer to the following.
• Page 107, Appendix 2 (12)
• Page 107, Appendix 2 (13)
• Page 108, Appendix 2 (14)
• Page 109, Appendix 2 (15)
(1) 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 reading and writing
Automatic update
Parameter access
Parameter batch read
Parameter batch write
The readable/writable parameters are listed below.
: Possible, : Impossible
Parameter name
*1
Device parameter
AnyWireASLINK
parameter
*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.
methods
The current status of all slave modules and the current values of the
sensors are read at regular intervals. (Excluding the setting values.)
By specifying the access method (read or write) and target slave module,
all the parameter values of each slave module are read or written
individually.
All the parameter values of all slave modules are read out into the buffer
memory of the master module.
All the parameter values of all slave modules are written into the buffer
memory of the master module.
