6 SENDING COMMANDS
Commands are primarily used for calibration of the TA500 via the EtherNet/IP™ interface. If the web interface
or the push button method is used for calibration, users can dis-regard this section of the manual if they are not
interested in additional features.
Utilizing calibration commands via the EtherNet/IP™ interface can enable machine builders to create a more
robust and efficient machine commissioning routine for their customers or builders without the need to physi-
cally locate the amplifier and push buttons for legacy calibration techniques. Below is a list of the available
commands and their definitions:
*
Transducer (load cells) should be loaded with appropriate calibration weight before this command is sent
These commands are used to establish a two-point calibration in the amplifier. During the calibration process
the gain is automatically calculated in the amplifier. The Calibration using the Ethernet/IP Interface section de-
fines how to use calibration commands in more detail.
All Commands are processed only on a command transition. The command register should be set
to zero when no command is requested and after a command is processed. Users may find the bit ‘Command
Processed’ useful when developing command logic. See the Input Tags Status Bit section for the bit location.
6.1 FINDING THE IP ADDRESS
If the IP address of the TA500-EIP is unknown, there are a few methods which can be used to find its current
IP address or re-establish a default IP.

VALUE COMMAND DEFINITION
0 No Command No command requested, Idle.
1 Zero Amplifier
Command the TA500 to establish a zero-point, part of the cali-
bration process. This command is always used before a Cali-
brate 10% or 25% command.
2 Calibrate 10%
*
Calibrate the amplifier using a calibration weight equal to 10% of
the full range.
3 Calibrate 25% *
Calibrate the amplifier using a calibration weight equal to 25% of
the full range.
4 Lock Amplifier
When the amplifier is locked it prevents button operation at the
unit, such as zero, calibrate, or reset.
5 Un-Lock Amplifier
When the amplifier is un-locked, buttons at the unit function as
described in the manual. (DEFAULT)
6 Reset Calibration Forces the Amplifier to an un-calibrated state.
7 Set Gain Gain can be set manually for advanced users.
