19.14.1 Data Block Display Graph - Graph/Basic

Number of Channels

Select the number of channels to display on the graph. The setting range is from 1 to 20.

Channel Number

Choose a channel number. Change to the value of [Number of Channels] to set the control address or scaling.

Control Word Address

Set the address that controls the displaying/clearing of the graph.

This address' bit 0 and bit 1 control when the graph displays and clears.

This can be set to either a PLC address or a display unit's internal device address.

19.10.3 Data Block Display Graph Structure

Number of Channels Address

Displays the address at [Control Word Address] + 1. This address stores the number of sets of data lines displayed on the graph. On the graph, this will become the number of sets of data samples.

For example, number of data: 7

The range depends on the set model's Display Number of Dots.

Data Storage Start Address/Offset Value Storage Address

Displays the address at [Control Word Address] +2. This address stores the start data displayed on the graph.

When an [Offset] is set, this changes to the [Offset Value Storage Address].

Scaling Settings

Data Type

Select the graph display data type from [16 Bit Bin], [16 Bit BCD], [32 Bit Bin], [32 Bit BCD], or [32 Bit Float].

  • If [Individual] is selected in the Detail Settings, individual channels settings can be modified.

  • If [Display Range] is selected in the Detail Settings, only [16 Bit Bin] or [32 Bit Bin] can be set.

Offset

Select whether to display an offset on the graph.

19.10.3 Data Block Display Graph Structure

Sign +/-

Set whether graph display data can handle negative numeric data. This can only be set when the [Data Type] is [16 Bit Bin] or [32 Bit Bin].

Only positive numeric data will be handled.

Negative numbers are handled with 2's complement.

Negative numbers are handled with MSB sign.

Min./Max.

Select the source data range for graph display data.

The set up range differs depending on the [Data Type] and [Sign +/-].

  • The corresponding [Source Range] in the word address is converted as a ratio of 1000 for display in the graph.

Display Sign +/-

Set to display negative numbers. This can only be set when the [Data Type] is [Bin]. When the [Data Type] is [BCD], the [Display Sign +/-] is disabled. When the [Data Type] is [Float], the [Display Sign +/-] is enabled.

Min./Max.

Set the range's minimum and maximum values to display on the graph. If [Display Sign +/-] is selected, the minimum value is -100. If it is cleared, the minimum value is zero. The maximum value is 100.
