Finding the right Interface Controller

Based on existing IO-Block (e.g. Profibus), the protocol ASIC has to be replaced by a Mitsubishi ASIC

Schematic for Implementation

Sourcing the specified parts (filter, zener diode) in Europe was not so easy

Help from Mitsubishi/CLPA

CC-Link Conformance Tests

Pre-Tests have to be done by manufacturer

All tests are simple to apply, exept one:

The noise test•The necessary equipment (noise simulator, isolation transformer) is not known in Europe and difficult to source.CLPA offers that the tests can be done in Japan

First tests were made in Japan•Meanwhile CLPA in Europe ordered the equipment for their lab.

Following tests were made in Ratingen•After the tests are passed these modules are directly sent to CLPA in Japan and they made the CC-Link conformace test.

Expeditures

Hardware development 35% project time

Software development 25% project time

Tests (Pretest and conformance test) 40% project time

Conclusion

The reference manual covers nearly all questions. All other questions are answered by Mitsubishi/CLPA
