Field Description
Name Enter the name for the selected graph.
Sampling Specify the Start Device (i.e. address) for sampling.
Data Format Specify the format of the data to be sampled.
Number of Lines Specify the number of devices to be sampled, i.e. the number of addresses to
be read, beginning with the address of the start device.
Sampling Trigger Specify the sampling trigger:

With the "GT Timer", also set the "Sampling Interval" in seconds.

With "Device Condition", specify the PLC register and whether a rising or a
falling edge should trigger sampling.
Record Area Number of Records for Each Line: Set the number of records to be stored.
The value you enter must be greater than the setting in "Number of Plots" on
the "Basic Setup" tab for the line graph part (see p. 208). The current maximum
number of records is displayed below for your information. The alarm history
and the line graph use the same memory area so the recordable maximum may
vary considerably (see notes below).

For general purpose serial communication, the start device needs to be an
internal GT register, e.g. WGR10 (default setting).

The total memory for the alarm history and the sampling data for line graph
parts (see p. 208) is 28160 bytes. Each line graph requires 16 bytes of
memory initially plus the data required for each point.
