Fill station
Requirements for a fill station
A box shall be filled with two different items, up to a specified total for each item. When all
items are in the box, it will be transported to the packaging station. A conveyor belt
transports the items of both types to the box. (This example does not show the filling
conveyor belt.) This circuit program for this example uses two up/down counters to count the
items of each type, a mathematic instruction to sum the total number of items, and message
texts to be displayed on the LOGO! onboard display and LOGO! TD (Text Display) that show
the number of items of each type and the total number counted so far.
This process is described below:

This process is described below:
● To fill the box, each item is transported by a conveyor belt to the box (not part of this
example).
● The sequence in which the items fall into the box is random.
● Each item that falls into the box is counted by a sensor.
● The connected LOGO! TD as well as the LOGO! onboard display must display how many
● Each item that falls into the box is counted by a sensor.
● The connected LOGO! TD as well as the LOGO! onboard display must display how many
items of each kind have been counted, how many total items are in the box.
The circuit program in LOGO!Soft Comfort
Light barriers are connected to the two digital inputs I1 and I2 sensors that detect when an
item falls into the box. The two counters (B001 and B002) count each item for the two
specific types of items as they fall into the box. The on-threshold of each counter specifies
the maximum number possible for each item type. When the box is full, a conveyor belt
activates for ten seconds to transport the filled box to the packaging station and to transport
an empty box to the fill station.
The circuit program uses a message text function block (Page 315) to display on the
The circuit program uses a message text function block (Page 315) to display on the
LOGO! TD and LOGO! onboard display how many total items and how many of each type
have been counted. The message text uses the "ticking" feature to alternate between
displaying bar graphs of the counted items and displaying a text summary of the counts.
