14.11.1.9 Numeric Display - Operation Process

You can perform an arithmetic operation on the data read from the device/PLC, and display the resulting data.

Processing

Set whether to perform an arithmetic operation on the data stored in [Monitor Word Address] and display the result.

In the following cases, [Processing] cannot be set:
When [Specify Input/Display Range] is set.
When [Alarm] is set.

Operation Data Specification

Select the method to set the data to operate.

Constant

Write a set constant as the data to operate. (Direct Specification)

Address

Designate the address which stores the data to operate. (Indirect Specification)

Indirect Area Specification

If the [Operation Data Specification] is [Address], choose the designation method for the address which will store the data to operate.

Area After Display Address

Arithmetic operations take place using the values stored in the [Monitor Word Address], and the address that follows.
Example: When Operation Data Specification is [Address], the Indirect Area Specification is [Area After Display Address], and the Operator is [+].

Individual Settings

Select a separate word address for the operation data.

Monitor Word Address

The [Monitor Word Address] specified on the [Basic] tab displays.

Operation Data

For [Word Address] data, set the other data.

If the [Operation Data Specification] is set to [Constant], enter the operation data here. Each [Data Type] on the [Basic] tab has a different size range. If [Address] is set, specify the address where the operation data will be stored.

Data Type		Sign +/-	Range
16 bit	Dec	Disable	0 to 65535
	Dec	Enable	-32768 to 32767
	Hex	—	0 to FFFF(h)
	Oct	—	0 to 177777(o)
	Bin	—	0 to FFFF(h)
	BCD	—	0 to 9999
32 bit	Dec	Disable	0 to 4294967295
	Dec	Enable	-2147483648 to 2147483647
	Hex	—	0 to FFFFFFFF(h)
	Bin	—	0 to FFFFFFFF(h)
	BCD	—	0 to 99999999
	Float	—	-9.9e¹⁶ to 9.9e¹⁶

Data Position

Select the Operation Data or Destination Word Address display position from [Right] or [Left].

Operator

Choose an operator from [Addition (+)], [Subtraction (-)], [Multiplication (*)], [Division (/)], [Logical AND (&)], [Logical OR (|)] or [Exclusive OR (^)].

When the data format for a calculation is 32 bit Float, only addition, subtraction, multiplication and division can be performed.

Any overflowing digits resulting from an arithmetic operation will be ignored. For example, when [16 Bit Hex] is set, the result of "FFFF(h) + 1(h)" would be "0000(h)".
If a division produces a remainder, an error may occur as a result of rounding the decimal point.
Results of base address + offset value calculations are always handled as 16 bit Bin values, regardless of the data length and data format settings.
If a calculation result exceeds 16 bits (maximum value=65535), bit 0 to bit 15 are handled as the valid bits and the higher-order bits are discarded.
