As business requirement in most of the Labs , needs be measured by electronic test equipment ** such as calipers, gauges, balances, pH-meters and so on
This interface enables us to transfer the inspection data measured by electronic test
equipment to QM inspection characteristics.
**A Test equipment has the following properties
Unidirectional interface capability.
Usually COM (Serial) Port communicator, can read the data from instrument , but can not write back (or hold) data in the instrument hardware.
Assumption: Test device feed data files into a common folder where MII services can access those files
Steps:
1.Download inspection lots information
2.Populate list of inspection and characteristic
3.Read electronic test equipments data from a share folder
4.Populate Web UI
5.Get Inspection Lot and Result value as a user input
6.Validate user inputs
7.Update Inspection lot characteristic with result
8.Return Message to user
9.Delete test device data file
10.Re-fresh web page
11.Transaction complete
Now Create an Inspection Lot in SAP
The above screen shows that how the inspection lots being created in SAP QM
login to SAP MIII, the user will be re-direct to relevant Lab instrument interface screen
Here basically, user need to select which Lab instrument , he is get connected with his computer and need to select the instrument
Once Instrument get connected, the add-in applications responsibilities to pull the data from RS232 port ,where lab instrument get connected.
I have developed an .Net application which basically listen the RS232 port and pull the data write in to text format.
Those value should be read by SAP MII transaction actions and then, populate the data in the User screen,
Now, User
need to select the data and submit, the result will be post to SAP QM Inspection lot(Which is selected by user) through SAP MII IDoc interface.Here ...SAP MII, the user HTML button click action called the java script and execute the SAP MII transaction and post the result to the inspection lot
Here ..SAP QM screen to verify the result update
Above solutions for the lab instrument that couldn't communicate both direction, where now we have comfortable lab instrument like CDS and other instrument can populate the data and communicate with computer systems, the blow diagram show how its possible to connect with CDS systems
Please contact me for any queries.....
