If you want to provide mock signals for the Pally program from another thread, set the data source of the corresponding IO channel type (element 0 of the array) to either -1 or -11 in runtime.

The name of the relevant IO channel variables

...

The variable names are listed below.

• rf_in_1_product1: first product sensor on the primary conveyor

• rf_in_1_product2: second product sensor on the primary conveyor

• rf_in_1_product3...8: additional sensors on the primary conveyor (up to 8 supported)

• rf_in_2_product1: first product sensor on the secondary conveyor

• rf_in_2_product2: second product sensor on the secondary conveyor

• rf_in_2_product3...8: additional sensor on the secondary conveyor (up to 8 supported)

• rf_in_overflow1: priority sensor on the first conveyor

• rf_in_overflow2: priority sensor on the second conveyor

• rf_in_button_P1: right pallet confirmation signal

• rf_in_button_P2: left pallet confirmation signal

Info
Remember: To change the IO type, update the 0th element of the array, e.g. rf_in_1_product1[0] = 0

Info
Remember: To change the IO channel, update the 1st element of the array, e.g. rf_in_1_product1[1] = 7

Examples

Example: simulate the operator has pushed the Right pallet confirmation button:

rf_in_button_P1[0] = -11 # simulate user pushed the button

...

sleep(0.5)

...

rf_in_button_P1[0] = -1 # simulate user released the button

This will detach the program from the physical IO channel and evaluate as True and False.

Example: simulate a product on the first pick position on the primary conveyor

rf_in_1_product1[0] = -11 # simulate product presence

Example: switch between 2 digital inputs depending on box size (experimental)

if (big_box):
  rf_in_1_product2[1] = 3 # usign DIGITAL IN 3
else:
  rf_in_1_product2[1] = 2 # usign DIGITAL IN 2
