Flexible Decoding and Processing of Data Matrix Codes with S7-1200 (CE-X27)
#1
Automation task
At a company’s goods receipt delivered goods are to be recorded by the HawkEye HE40 Data Matrix code scanner. The scanner is to transfer the read data via a serial connection using a RS232 communication module CM1241 to a S7-1200 controller (CPU1214C).

To be able to scan bulky goods it will furthermore be possible to buffer the read data, whilst there is no connection to the controller. In this case, the reading of the buffered data will take place automatically after restoring the connection to the controller.

To identify the recorded products, the program of the S7-1200 is to pass on the read ID code to a PC via the Ethernet interface. The OPC server PC ACCESS installed there presents the connecting link to a downstream database (e.g. MS ACCESS), in which the product description of the read code is searched in the selected language. The product description is then re-transferred via the OPC server back to the S7-1200 controller and is then displayed on a Basic Panel KTP600. Parallel to the reading process of each product a time stamp it to be recorded in the database.
STEP7 Basic v10.5is to be used as configuration tool for the control program and the HMI.
