DMC’s client had a test stand designed to evaluate several products in the current line. The test stand used a Siemens SoftPLC as well as a custom DLL driver to allow communicating with the appliances under test using its diagnostic port. With the addition of new products to their factory, additional tests and modifications to existing communication parameters were required.

DMC reviewed the existing design and requirements for additional tests and worked with the client to implement them on their test stands. DMC updated the PLC test sequence and interface to include the additional tests.  Additionally, DMC upgraded the communication DLL integrated into the SoftPLC to fix several stability issues when communicating with the appliance under test.

The client was able to successfully integrate the new products into their process as well as improve testing efficiency.
