DiagSig

The #DiagSig (diagnostic signal) object is used to indicate errors by the flashing of the object. The #DiagSig can be used for example to indicate specific information about the cause of a fault on the machine in response to alarm messages. For example, the location of a fault can be indicated on a photograph of the machine (e.g. faulty limit switch). The #DiagSig object checks the specified text string with the current variable value, or whether the corresponding alarm number is active. It then activates the flashing point if the condition is fulfilled.
