than this address. Set MSD switch to this number's corresponding HEX digit.

The address stored in the internal EEPROM is modified via the Set Slave
Address command. If the address switches are set to 126 (or 126 to 254)
upon power-up, the module will retrieve the last address stored within its
EEPROM (126 from the factory). With both the internal EEPROM and
external switch addresses set to 126, the unit will await the Set Slave
Address command after power-up, before proceeding to the
parameterization state (address 126 cannot be used in data exchange mode
and is reserved for commissioning purpose only). You must use the Set
Slave Address command to change the internal (EEPROM) address
following power-up in order to proceed. However, if the switches are set to
an address less than 126 upon power-up, then the switches determine the
slave address and the EEPROM setting is ignored. You can later restore the
internal EEPROM setting to 126 by powering the unit up with the address
switches set to 255 (FF). You would then power the unit up again with these
switches set to 126 in order to return the unit to its commissioning state.
When attaching the module to the T-type DIN
rail, angle the top of the unit towards the rail
and locate the top groove of the adapter over
the upper lip of the rail. Firmly push the unit
towards the rail until it snaps into place. To
remove, first separate the input terminal
block(s) from the bottom side of the module to
create a clearance to the DIN mounting area.
Next, while holding the module in place from
above, insert a screwdriver into the lower arm
of the DIN rail connector and use it as a lever
to force the connector down until the unit
disengages from the rail (do not twist the
screwdriver to avoid damaging plastic).
Address is set to 126 (7EH)
from the factory. This address
is reserved for commissioning
purposes only.
Locate hexadecimal address
switches in recessed opening
next to the power terminals.
Use a screwdriver to rotate
these switches to set a unique
valid address from 0 to 125.
If the switches are set to a
valid address from 0-125, then
the switch setting determines
the slave address and the Set
Slave Address software
command will be rejected.
If these switches are instead
set to 126 (7EH) upon power-
up, the unit will retrieve its
address from the internal
EEPROM, which is modified
via the Set Slave Address
command.
If these switches are set to
255 (FFH) upon power-up, this
will return the address stored
in EEPROM to 126 (7EH).
