Page 294 9 Visualization Outputs Output (BOOL) Parameter None Function If all configured inputs are TRUE, the output is FALSE, otherwise it is TRUE. Initial state All inputs and outputs are FALSE. Non-configured inputs are assumed to be TRUE so that they have no impact on the output. If no input is configured, the output therefore remains in the initial state of FALSE.
Page 295 9 Visualization Parameter None Function If an odd number of inputs is TRUE, the output is TRUE, otherwise it is FALSE. Initial state All inputs and outputs are FALSE. Non-configured inputs are assumed to be FALSE so that they have no impact on the output. If no input is configured, the output therefore remains in the initial state of FALSE.

If Input has a falling input, the internal timer is set to zero and starts to run. When the internal timer has reached or exceeded the parameter value, Output becomes FALSE and the counter stops running.
Page 298 9 Visualization Function The internal timer runs for a long as Enable is TRUE. When the internal timer has reached or exceeded the configured time value, the status of the output changes and the timer is restarted. The configured time there- fore corresponds to half the period duration of the re- sulting signal.
