6.1.5 Controlling the ZMX Sensor
Using Input Bits
Writeable Input Bits are inputs to the sensor (outputs from the PLC or HMI). They are used for basic control of the sensor.
Toggle them from 0 to 1, one at a time, to request the associated action. Most bits have a corresponding ACK Output bit that
changes to 1 in response, to indicate that the action has been completed. The ACK bits reset to 0 when the command bit is
reset to 0.
Update ROI Parameters—This action tells the sensor to take all of the new bin fill parameters, as a group, and apply
them to the sensor.
1. Enter the desired PLC Output values for all bin fill parameters:
•
Fill Level Setpoint (word 20)
•
Peak Height Limit Setpoint (word 22)
•
Discrete Output 1 Control Mode (word 24)
•
Discrete Output 2 Control Mode (word 25)
•
ROI Anchor Point X (word 26)
•
ROI Anchor Point Y (word 27)
•
ROI Anchor Point Z (word 28)
•
ROI Length (X) (word 29)
•
ROI Width (Y) (word 30)
•
ROI Height (Z) (word 31)
2. Toggle the Update ROI Parameters bit (word 0, bit 0, PLC Outputs) from 0 to 1.
3. Look for the corresponding Update ROI Parameters ACK bit (word 0, bit 0, PLC Inputs) to go from 0 to 1.
4. Confirm that the Configuration Error bit (word 0, bit 15, PLC Inputs) is still 0.
If it is a 1, read the Configuration Error Code (word 21, PLC Inputs) and correct the error. See
Codes
on page 45.
Save Parameters Permanent— This action tells the sensor to take all editable parameters modifiable over EtherNet/IP
and save them in the sensor's permanent memory. This includes the size and position of the Region of Interest, as well as
settings such as Trigger Mode and Output Control Mode.
Reset Application Results—This action resets all measurement output values to 0 in the EtherNet/IP registers.
Trigger—This action triggers an immediate image acquisition and measurement.
Enable Inputs—This bit controls whether changes to basic sensor parameters like Trigger Mode, Trigger Period,
Illumination Power, Pitch, Roll, and Yaw Angle, and Discrete I/O Polarity should take effect in the sensor. To adjust these
parameters on the fly:
1. Toggle the Enable Inputs bit from 0 to 1 (word 0, bit 14, PLC Outputs).
2. Adjust any of the above parameters as needed.
The new values will take effect only if the Enable Inputs bit is a 1 and the new value written represents a change from
the previous value.
