Remote Address Change Function

With this function, an ID (address) of a slave module can be changed using the buffer memory area without an address writer.
Applicable slave module
For the slave modules that support the remote address change function, contact Anywire Corporation.
Operating procedure
1.
Execute automatic address detection to check that no error has occurred in the AnyWireASLINK system. (Page 55
Automatic Address Detection Function)
2.
Specify an access method to a slave module.
Store 0002H (address change) in 'Parameter access setting' (Un\G10320).
3.
Specify an ID of the slave module to be accessed.
Store the ID to be changed (old ID) in 'Parameter access target module ID specification' (Un\G10321).
ID
0000H to 00FFH
0200H to 02FFH
4.
Specify a new ID of the slave module.
Store the new ID in 'Change ID specification' (Un\G10323).
ID
0000H to 00FFH
0200H to 02FFH
If the specified ID has already been used or is out of the allowable specification range, an error occurs.
5.
Turn on and off 'Parameter access request command for the slave module' (Un\G27 b8).
At this time, 'Parameter access completion flag' (Un\G28 b9) turns off. When the parameter access is completed, 'Parameter
access completion flag' (Un\G28 b9) automatically turns on.
6.
After changing the IDs of all the target slave modules, execute automatic address detection. (Page 55 Automatic
Address Detection Function)
Precautions
• Before executing this function, make sure to execute automatic address detection to check that no error has occurred in the
AnyWireASLINK system. (Page 55 Automatic Address Detection Function)
• This function cannot be executed for slave modules separated from the FX5-ASL-M because of disconnection or slave
modules having the same ID. Use an address writer to change the IDs of such slave modules.
• This function can be executed if only one slave module having no ID exists within one AnyWireASLINK line. If IDs of
multiple slave modules are not set, it is recognized as an ID duplication. Thus, the IDs cannot be changed.
ID
0200H 0210H
Description
ID of the output slave module
ID of the input slave module or I/O combined slave module
