Alpharetta, GA – Siemens Energy & Automation introduced Feb. 25 its Simatic Diagnostic Repeater, which it reports is the only device capable of delivering online diagnostic information about RS-485 Profibus cable during operation. The easily installed Diagnostic Repeater is designed to help users reduce plant downtime, speed commissioning and integrate system diagnostics in new or existing networks, installations, and components.

Diagnostic Repeater also monitors and detects wire breaks, short circuits and missing terminations between sections of RS-485 Profibus cable, and instantly reports this information to the DP master, which forwards the data, including the cause of a fault and location, to all connected HMI devices. Information can be displayed in clear text, eliminating the need for hex-code interpretation. A graphic display depicting the fault and fault location is available with Step 7 or COM Profibus. In addition, diagnostic and statistical data can be saved with Siemens Step 7 V5.2 software.

Diagnostic Repeater can be snapped onto a standard DIN rail or Siemens S7-300 mounting rail. Siemens’ Fast Connect terminals connect sections of Profibus in seconds.
