Line Graph Control - Panasonic GTWIN Reference Manual

Introducing GTWIN

1.6.11.1 Line Graph Control

When you have defined one or more line graphs, the line graph control function becomes
available. Select "On" if you want to use it and then select a register as the control device.
The control device helps you monitor sampling data for up to 5 graphs and allows you to
perform the following functions for each graph: start and stop sampling data, check the status,
or clear the memory. The table below explains the bit assignment of the control device.
Bit: F E D
Gr. 4 Gr. 3 Gr. 2 Gr. 1 Gr. 0
Start device
number N + 0
Gr. 4 Gr. 3 Gr. 2 Gr. 1 Gr. 0
Start device
number N + 1
Gr. = Graph
When a bit is set, the status is true, i.e. the function is executed. For example, when bit 9 is
set to 1, the memory for graph 1 is full. Clear it by setting bit 1 of byte N+1 (WGR31 if WGR30
is the control device selected) to 1.
