The Fieldbus Foundation (FF, www.fieldbus.org) released a FOUNDATION fieldbus H1 cable test specification. The spec includes test cases, providing greater assurance to automation end-users that their wiring systems are suitable for fieldbus system operation.

The H1 Cable Test Specification (Document FF-844) is designed for manufacturers developing cables for FOUNDATION fieldbus H1 (31.25 kbit/s) installations. The specification test cases, based upon the IEC 61158-2:2003 standard, include impedance, capacitive unbalance, connector pin-outs, and attenuation.

Cable manufacturers can submit their test reports to the Fieldbus
Foundation, which will initiate a cable registration process in the near
future. Fieldbus Foundation members can download the specification on Fieldbus Forums. For more information, e-mail [email protected].
