2.8.5 ACT, Active Channel Dialogue
By defining active channels a "live" up-to-date relationship between an Insight or COS
picture and VISONIK system data points or process is established.
T8 14:17:02 Function=PNT : COS
Dialogue Range=UTIL : ACT
Operation=CH : ?
0 CH = Change Data Entry
1 LI = List Data Registers
2 DEL = Delete Register Entry(ies)
Operation=CH :
2.8.5.1 ACT,CH, Enter or Change Active Channels.
The extensive dialogue COS,ACT,CH can be split into three sections. The first and third
sections are used for all active point types whereas the second section depends very
much on the selected active point type.
The dialogue must not be followed through from beginning to end, in particular when
changing an entry where the dialogue can be terminated after a relative modified entry.
(But, at the earliest, after entry of each channel type)
For new entries the dialogue takes default values from the previous entry. This means
the dialogue work is reduced for similar successive entries.
Changes to existing active channels of pictures currently being displayed somewhere
will be updated after a short time.
To display newly entered channels, however, the affected picture must be newly called-
up.
First Dialogue Section: Initial Prompts
[A picture number in the range (1..max)]
Calls up that picture to which the subsequent entries relate.
[A channel number in the range (1..max)
Calls up the channel (defined at Insight/COS picture generation) to be actively updated.
[Fix I/O..Fix Outp]
Active channel type
The channel type denotes if the associated actively updated parameter in a picture can
be cursor selected for "Action from Picture" operation or not.
In addition, in special pictures, the value of a parameter can be displayed in a defined
window (with scroll).
Fix I/O Fixed channel position with input and output:
The parameter allocated to such a channel can be cursor selected.
Accordingly, an input may also be given to such a channel.
Fix Outp Fixed channel position with output only:
Such a channel can only display an output value and cannot be cursor
selected.
