Monitoring Data

Measured Weight (offset 0, 15, 30, 45)

 

 

image-20240325-061246.png

This weight is the most primitive weight. It is not affected by any other commands during normal operation. Only the calibration and span (command main code : 5 and 6) commands can change its property. Left figure shows all the weight values provided by WG0nA module and their characteristics.

 

 

Status Flags (offset 2, 17, 32, 47)

 

Following table shows the bit mapped flags of WG0nA module. The flags from bit 8 to F can be used as input only for the batch control.

Bit

Flag

ON condition

0

Zero

On when net weight is within the zero range

This flag is affected by the set value of zero range (offset 74, 120, 166, 212)

1

Stable

On when current weight is within the motion detection range during motion detection time. This flag is affected by the set value of motion detect range (offset 75, 121, 167, 213) and time (offset 76, 122, 168, 214)

2

Over weight

On when gross weight is above the Max. weight set value.

Over

On when net weight is above the ‘over weight’ set value.

(offset 102, 148, 194, 240)

9

Under

On when net weight is below the ‘under weight’ set value.

(offset 104, 150, 196, 242)

A

Hopper-Full

On when gross weight is above the Max. hopper weight.

(offset 114, 160, 206, 252)

B

Batch Completed

On at the end of batch process.

C

Batching time over

On when the time of batching process is over the set period.

Gross Weight (offset 5, 20, 35, 50)

 

This weight is the zero applied measured weight (offset 0, 15, 30, 45). Zero can be applied by Y6/7/8/9 output signals.

 

 

Tare Weight (offset 10, 25, 40, 55)

 

This weight is the tare applied gross weight (offset 5, 20, 35, 50). Tare can be applied by YA/B/C/D output signals.

 

 

AD data (offset 12, 27, 42, 57)

 

24 bits raw data from ad converter. This value is used for calculating the measured weight. (offset 0, 15, 30, 45)

 

 

Error code (offset 14, 29, 44, 59)

 

The error code of each channel is stored in this field. In normal state this field holds zero. When an error is occurred, non-zero value is stored in this field and error input signal (XA/B/C/D) of relevant channel is turned on. The error code and signal can be cleared by ‘error clear (1)’ command after removing the fault reason. Following table shows the detailed error code summary.

 

Code

Error

Description

H0000

No error

 

H0001

No sensor

Check the loadcell cable and its connection

H0002

Batch time out

Batch control is not completed within the period of setting (offset 113, 159, 205, 251)

H0003

Unstable at zero operation

Zero operation (Y6/7/8/9) is issued at unstable state. Zero operation can be re-issued with this error.

H0004

Unstable at tare operation

Tare operation (YA/B/C/D) is issued at unstable state. Tare operation can be re-issued with this error.

H0005

No external power supply

Check the external 24Vdc power supply.

H0010

Unknown command from sequence

Check the version of WG0nA and CPU module.

H0011

Parameter error on instruction

Check the parameter of  WGBATCH instruction in sequence program.
