6. COMMAND REFERENCE 175
#
Set comms address remotely
Syntax Units Range of ‘n’ Default See also
a#n - 1 to 255 0 -
Description This command (#) allows you to set the unit address via software. It allows
addresses up to 255 to be used. Upon receipt of the command, the
controller will send a #n+1 command along the daisy chain provided the echo
mode is set. Once received you must send a SV command to save the
address configuration.
To address a specific axis place the current address ‘a’ before the # symbol.
0#0 is not supported on this product.
Auto addressing can be used, for example sending #1 to axis 1 of a 3 axis
system will echo back #4 (meaning the axes have been given addresses 1, 2
& 3). Save the address configuration of all axes using the command 0SV.
The command can be used to specify the style of communications required,
for example 1#4(232) will set axis 1 to address 4 and specifies the use of
RS232. Note this form of command is immediate and is auto saved as soon
as you hit return, consequently take care. If you have no RS485 interface
fitted to your PC and you issued 1#4(485)* the drive will switch to RS485 and
will auto save the change, leaving you without any means of communicating
with the drive. See Forcing a Hardware RFS in the Maintenance &
Troubleshooting section.
Auto addressing can be used with style of communications type commands,
allowing such commands as #n(232) or #n(485) where n is the primary axis
you wish addressing to start from.
*You must have a RS485 drive module fitted for the drive to recognise the
command.
Properties
Immediate or buffered, can’t be used in labelled block, saved by SV
Example If a system with axes 1,3,7,2 (in that order) is sent the command #10,
the axes will become 10, 11, 12, 13. Note that the #10 will not be
displayed on your PC screen, but you will receive the response #14
after pressing the enter key.
For multi-axis systems using RS232, auto addressing can be used when
the drives are interconnected via the RJ45 connectors (X6 & X7).
Primary communication needs to be via the front panel D-type X3
connector.
