I-BIT / Invalid |

Set |

Available |
with all drivers |
This bit is set, if there is a problem in the communication with the driver or with a single variable. The evaluation of single variables is only supported by spontaneous drivers. Most of the zenon drivers however are polling drivers, thus only a general problem in the communication can be indicated (and not a separate one for each variable).
