Equipment for Logical Tests

The Sercos II Conformizer is used for the logical tests. This tool performs a strict and reproducible test for Sercos interface master and slave implementations and is available to all Sercos product suppliers as a pre-test tool. Purchase of this tool for pre-testing of products is strongly recommended, as it provides a 90% assurance of passing the formal test.

The Conformizer parses test scripts, which contain the test descriptions in a readable format (ASCII). Additional test scripts can be easily integrated to support quality assurance within a company.

The Conformizer tool can be purchased from Sercos International.

In addition, the Sercos Monitor is a useful tool. It allows the recording of traffic on the optical ring. A record can be traced, filtered and analyzed.
