3.3 Industrial protocols
The PENKO protocols Modbus, Profibus, EtherNet/IP and ASCII have a function set called
register functions. These functions allow the user to configure and control the device.
Protocol descriptions can be downloaded from www.penko.com
Consult these on how to connect the device and use the register functions.

4Parameters
These parameters correspond with the parameters in the tree structure of the device Recipe.
When using the industrial protocol register functions, each parameter can be reached using its
number.
Some parameters can be reached directly using ASCII, TP protocol, Modbus RTU, Modbus TCP,
Fins, Profibus or EtherNet/IP. The parameters for Profibus or EtherNet/IP are prefixed with PB
or EIP.
Note: when the device is rebooted or the recipe is manually changed, all recipe parameters are
changed back to the value that were last set manually in the recipe.
4.1 Configuration parameters
No.
Name
Description
1
Check mode
Select if the check weigher is used for dynamic or static
weighing.
•Dynamic => the product will move during weighing (belt is
running).
•Static => the product will be stopped during weighing (belt
is stopped when check input is high and restarted when
check is done).
2
Stability
Select the type of check delay. In static check mode the belt
will stop during the check delay.
•Off => check starts directly
•Stable => check starts after Stable
•H-Time => check starts after H-time
•H-Time+Stable => check starts after H-time and then
Stable
•H-Time/Stable => check starts after H-time or Stable
•Stable+H-Time => check starts after Stable and then H-
Time
3
H-Time
Time to wait for stable weight measurement.
Δ Not used if Stability parameter is set to Off or Stable
4
Display hold
The time to freeze the checked value on the display after the
check is done. When a check starts before the display hold
time is elapsed, the hold time will be cut off.

7Program basics
This chapter describes a few basics of the Check Weigher program which can be used when
starting the program for the first time.
7.1 Static check mode, Reject mode set to Time
With input 1 you can Start (input high) and Stop (input low) the program. The Transport Belt
(output 3) will start. With a pulse on Start Sampling (input 2) the checking will start. During
checking the Transport Belt (output 3) will stop and Sample Busy (output 2) is on.
When the checking is complete and the weight is ok, the Transport belt (output 3) will start
again, Sample Busy (output 2) is off. With a pulse on Start Sampling (input 2) the checking will
start again.
If the weight is below Low Level or above High Level the Transport belt (output3) will start
again. After the Reject Delay time, the Rejector (output 1) will turn on, and will remain on for
the duration of the Reject Hold time. With a pulse on Start Sampling (input 2) the checking will
start again.
7.2 Static check mode, Reject mode set to Photocell
With input 1 you can Start (input high) and Stop (input low) the program. The Transport Belt
(output 3) will start. With a pulse on Start Sampling (input 2) the checking will start. During
checking the Transport Belt (output 3) will stop and Sample Busy (output 2) is on.
When the checking is complete and the weight is ok, the Transport belt (output 3) will start
again, Sample Busy (output 2) is off. With a pulse on Start Sampling (input 2) the checking will
start again.
If the weight is below Low Level or above High Level the Transport belt (output3) will start
again. When the photocell (connected to input 3) has detected the product, the Rejector
(output 1) will turn on, and will remain on as long as input 3 (photocell) in on. With a pulse on
Start Sampling (input 2) the checking will start again.
