19.10.2 Displaying/Clearing a Data Block Display Graph

To display the graph, delay the Control Address' display bit (bit 0) by a time longer than the communication cycle time or 50ms (whichever is larger), after storing the data count and data values.
The communication cycle time is stored in the display unit's special relay internal device (LS2037).
Control address data is set to zero after the graph displays. to display the graph again, restore the data to the control address with a time longer than the communication cycle time or 50ms (whichever is longer).

Stores the graph display's data count in the [Number of Channels Address], and after storing the corresponding number of data starting from the [Data Storage Start Address] onwards, turns ON bit 0 of the [Control Word Address]. (For example, write 1 to the [Control Word Address])

Turn ON bit 1 in the [Control Word Address]. (For example, write "2" in the [Control Word Address]). The displayed graph will be deleted.

Turn on bit 0 and bit 1 in the [Control Word Address]. (For example, write "3" in the [Control Word Address]) After the displayed graph is deleted, the graph is redisplayed based on the current stored data.
