Hello maritov; This is the first time I hear of such behavior with a DP/DP Coupler.Normally I would have expected that invalid data would remain at the last known value. Here are some links that should help you diagnose the validity of the incoming data: Behavior of the DP/DP coupler when a master system fails Reduced user data capacity when using the diagnostics From the DP/DP Coupler manual (a link is available in the second FAQ): Function principle of the data validity indication The DP/DP Coupler enables the data transfer between two PROFIBUS DP networks. Function of the “DIA” DIL switch (data validity indication) The “DIA” DIL switch function allows you to validate I/O data. The setting of the “DIA” DIL switch does not influence the normal diagnostic messages of the DP/DP Coupler described in chapter 6.2. “DIA” in “OFF” position I/O data validation is disabled when the “DIA” switch is set to “OFF”. “DIA” in “ON” position I/O data validation is enabled when the “DIA” switch is set to “ON”. Hope this helps, Daniel Chartier |
