General Information

Description

The library PD_MultiBelt, compatible with the PacDrive controllers, is a collection of technology functions for grouping products using parallel belts. The table below depicts an example for each of the most common use cases.

NOTE: For this library, qualified-access-only is set. Therefore, the POUs, data structures, enumerations, and constants have to be accessed using the namespace of the library.

NOTE: Only Controller OnBoard I/O touchprobes and drive touchprobes are supported by the functionalities of this library. TM5 module touchprobes are not supported.

Three belt grouping	Four belt infeed

You will find information about the application and parameterization of the library here.

The key features of this library include:

Controlling several parallel belts - tested for up to four belts
Defining several stations for loading and unloading products - tested for up to three stations
Defining up to 127 compartments per train
Mounting several trains per belt - tested for up to two trains
Filtering of sensor signals
Performing warm start routines

This library has been designed to cover a general range of use cases. If you need further features for your application, contact your Schneider Electric representative to find an individual solution.

Characteristics of the Library

The following table indicates the characteristics of the library:

Characteristic	Value
Library title	PD_MultiBelt
Company	Schneider Electric
Category	Application
Component	PacDrive
Default namespace	MTB
Language model attribute	Qualified-access-only
Forward compatible library	Yes (FCL)

NOTE: For this library, qualified-access-only is set. This means, that the POUs, data structures, enumerations, and constants have to be accessed using the namespace of the library. The default namespace of the library is MTB.

General Considerations and Restrictions

Besides these general considerations and restrictions, some features are only available for certain station types. They are described at their respective position within this library guide.

The servo axis type SercDrive is not supported.
The program calling the MultiBelt functionalities must be executed in a cyclical task.
In case two stations are located very close compared with the train length, the system may not move at all.
The feature xStationLock is not available.
In certain, rare scenarios, trains might move backwards and collide into one another. To avoid this, use the same value for ST_Station.lrTrainsDistances in all stations.

WARNING
	UNINTENDED EQUIPMENT OPERATION Use the same value for ST_Station.lrTrainsDistances in all stations. Failure to follow these instructions can result in death, serious injury, or equipment damage.
