Remote Address Change Function - Mitsubishi Electric MELSEC iQ-R AnyWireASLINK User Manual

1.3

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, consult Anywire Corporation.
Operating procedure
1.
Execute automatic address detection to check that no error has occurred in the AnyWireASLINK system. ( Page 58
Automatic Address Detection Function)
2.
Specify an access method to a slave module.
Store 0002H (remote 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 00FEH
0200H to 02FEH
0400H to 05FEH
0600H to 07FEH
4.
Specify a new ID of the slave module.
Store the new ID in 'Change ID specification' (Un\G10323).
ID
0000H to 00FEH
0200H to 02FEH
0400H to 05FEH
0600H to 07FEH
If the specified ID has already been registered or is out of the allowable specification range, an error occurs.
5.
Turn on and off 'Parameter access request command for the slave module' (Y10).
At this time, 'Parameter access completion flag' (X11) turns off, and 'Parameter accessing flag (with handshake)' (XB) turns
on. When the parameter access is completed, 'Parameter access completion flag' (X11) automatically turns on.
6.
After changing the IDs of all the target slave modules, execute automatic address detection. ( Page 58 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 58 Automatic Address Detection Function)
• This function cannot be executed for slave modules separated from the RJ51AW12AL 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.
