5.4 TENSION DATA AND STATUS
After the module is added input Tags carry the calibrated tension value if the unit is calibrated and other status
information of the device. If calibration of the unit is required see the section Calibration . All tag data is Signed
32–bit integer value. The input tags descriptions are as follows:
Input Tags:
STATUS_BITS
Status Name Definition
0 Amplifier locked No Button access is allowed for zero or
calibration
1 Calibrated at unit Indicates that the last valid calibration was
performed using the buttons
2 Zeroed at unit
Indicates that the last zero operation was
performed using the buttons
3-6 RESRVED Always Zero
7 Heartbeat Bit Bit toggles every 0.5 seconds approx.
8-13 RESRVED Always Zero
14
Command
Processed
Bit set High after a command is processed,
can be used in ladder logic to reset the
command register to zero (no command)
15 AMP OK SUMMARY Bit indicating no error status.
16-31 RESRVED Always Zero
AMP_STATUS
Status Definition
0x00000000 Amplifier OK – Normal Operation
0x00000001 Internal Failure
0x00000002 No cailbration
0x00000003 Out of Range – Amplifier is calibrated but is experiencing an overload or underload
condition.
0x00000004 A wiring error is detected – in rare occurnences this error could be caused by an extreme
overload conditions on load cells.
0x00000005 An error is detected with the excitation of the load cells – usually this means a short circuit is
present externally to the amplifier.
