WISL Process Management
WISL Process Management provides the link
between production and planning processes. It begins with the capability to maintain
records of and schedule production batches. It offers an interface with data collection
applications on the production line to provide production control information and retrieve
actual production data. Finally it includes an interface for WISL Production Analysis or a
third party MRP system to pass along the planned and actual production data.
Platforms
Server: Open Systems
- UNIX; AIX, Solaris
- Windows Server
- Linux; Redhat
Workstation: Text or GUI apps, anything that runs
AccuTerm terminal emulation ; text only apps, dumb terminal that emulates industry
standard term types
Includes:
- Windows PC
- Mac
- Thin client
- Various dumb terminals
RF terminals: Handheld or vehicle mount, may be
utilized. The user interface is text based and typically the manufacturer supplied
terminal emulation facilities are utilized.
Process control data collection devices: Fixed
mount devices running MS CE. The user interface is GUI utilizing the facilities of C++
Third Party Software
- IBM’s UniVerse DBMS
- AccuSoft’s terminal emulation package –
AccuTerm
RF Data Collection and Barcode Printing Hardware
WISL prefers to supply all RF data
collection and barcode printing hardware to insure compatibility with WISL software
applications, durability and ongoing support. WISL recommends Symbol for RF and Zebra for
printing barcode labels.
Process Control Hardware
WISL prefers to supply all process control
information processing hardware to insure compatibility with WISL software applications,
durability and ongoing support. WISL recommends Intelligent Instruments(a division of
Texas Instruments) devices.

WISL Process Control Software Modules
Installation Preparation
WISL PM provides for information systems
support of a variety process control applications but WISL does not provide engineering
support. The customer must provide the necessary in-house or third party expertise to
interface production processes(usually at the PLC level to WISL provided information
systems. For example in a production line labeling operation the label printers must be
synchronized with the line which is an engineering responsibility.
System Functions
Below is an image of the system flow of
WPM followed by a list of major functions:
- Maintenance of batch production records(the
building blocks for process control).
- An interface between the production batch data
base and spreadsheet facilities provides for the generation of a production batch
schedule.
- TCP/IP provides the interface between interactive
applications that run on intelligent terminals that control production line processes and
the data base on the server.
System Synopsis of WPM Sub-Modules
The WISL WPM Pinch
Points includes interactive routines that are designed
to provide for data collection and control at key points in the flow of the
manufacturing process.
Typically a hand held data terminal is utilized to
scan barcodes and collect control data while accessing the data base on the WISL Process Management server
but there is no direct connection to an automated manufacturing process.

| WISL Inventory Acceptance |
The WISL WPM Inventory Acceptance provides the
capability to maintain the jig record to indicate that it has been emptied and maintain
the date and time. It also generates a transaction which is batched and sent to the WISL
Warehouse Management Server to maintain the inventory data base.
A hand held data terminal is utilized to control
the process while accessing the data base on the WISL Process Management server.
The WISL WPM Jig Maintenance System provides for
control over packaged product on the production floor until it is accepted into inventory.
Jig records are generated to correspond to a
physical temporary storage and transfer device. An interactive routine that runs on an RF
data collection computer provides for the maintenance of the
current contents of a jig.
- WISL Production Control Reporting
The WISL PM Production Control Reporting System
provides information for controlling the production scheduling process. Orders, inventory
and production batch/work order data bases are assimilated and many calculations and data
relationships are generated in order to produce effective information for controlling
the production scheduling process.
- WISL Production Analysis Reporting
The WISL PM Production Analysis Reporting System
provides information for analyzing the production process. All data collection is done
relative to a specific batch by the shift supervisor at the end of a batch or at the end
of a shift. A file of data is maintained by batch ID and reporting
is generated from this and the batch schedule data base.
- System Synopsis of Sample WPM Process Control Application(Box Maker)
An Intelligent Instrument data terminal is
utilized on the production line to prompt for control data and supply the instructions to
run the process. Communication with the Process Management server is accomplished with
TCP/IP. The Batch control file is read from the server and the operator selects the
desired batch from the terminal display and the control process is initiated. Upon
completion, data about actual production is returned to the Process Management server.
