2.12.7.3 CHAN, Change DP Channels
A DP channel contains the characteristic data for displaying a dynamic point from
central DATA PROCESSING (DP).
A channel has a fixed configuration but may be changed or deleted at any time.
Ten DP channels can be allocated per graph.
A DP channel consists of two parts is very similar to a TREND channel in structure.
Elements in the dialogue are taken from the Trend dialogue:
•
Specific parameters (DP parameters) from DATA PROCESSING such as Address,
Parameter name, Type of Log, Interval, Memory type.
•
Graphics parameters such as Format, Colour, Pattern, Symbol.
If an entry already exists having the same channel number as the one in the current
dialogue, a short report is output with details on the existing channel:
