Controller Status

You can include the Controller status as a member of a tag set in the data sent and received. The Con-
troller status is a set of flags that indicate the operating status of the CPU Unit (operating information,
error information, Controller error level). If the Controller status is specified as an output (send) tag, the
Controller status is added to the start of the tag set in the following format. (Select the Include Option for
the Controller Status in the upper right of the Edit Tag Set Dialog Box.)

* Of the flags in bits 5 to 7 that indicate the current error level, only the flag for the highest error level changes to
TRUE. For example, if a minor fault level Controller error and a major fault level Controller error occur at the
same time, only the flag for the major fault level Controller error (bit 7) will change to TRUE and the flag for the
minor fault level Controller error (bit 5) will remain FALSE.
To receive the Controller status, specify the Controller status for the In - Consume Tab Page in the dia-
log box used to edit the receive tag set. (Select the Include Option for the Controller Status in the upper
right of the Edit Tag Set Dialog Box.) When a tag data link is started, the contents of the Controller sta-
tus is stored in the system variables that are given below.
