GetInputBool

Prototype:

GetInputBool(address)

Description:

Gets the boolean value at the specified input register address.

Required Parameters:

• address: Register address, valid range [0-63]

Returns:

The value at the specified register address, which will be either 0 or 1.

Example:

-- Execute subsequent operations when the value of input register 0 is 1.
if(GetInputBool(0) == 1) then
    -- Execute subsequent operations
end

GetInputInt

Prototype:

GetInputInt(address)

Description:

Gets the integer value at the specified input register address.

Required Parameters:

• address: Register address, valid range [0-23]

Returns:

The value at the specified register address, which will be an integer (int32).

Example:

-- Read the value of input register 1 and assign it to the variable regInt.
local regInt = GetInputInt(1)

GetInputFloat

Prototype:

GetInputFloat(address)

Description:

Gets the float value at the specified input register address.

Required Parameters:

• address: Register address, valid range [0-23]

Returns:

The value at the specified register address, which will be a single-precision floating-point number (float).

Example:

-- Read the value of input register 2 and assign it to the variable regFloat.
local regFloat = GetInputFloat(2)

GetOutputBool

Prototype:

GetOutputBool(address)

Description:

Gets the boolean value at the specified output register address.

Required Parameters:

• address: Register address, valid range [0-63]

Returns:

The value at the specified register address, which will be either 0 or 1.

Example:

-- Execute subsequent operations when the value of output register 0 is 1.
if(GetOutputBool(0) == 1) then
    -- Execute subsequent operations
end

GetOutputInt

Prototype:

GetOutputInt(address)

Description:

Gets the integer value at the specified output register address.

Required Parameters:

• address: Register address, valid range [0-23]

Returns:

The value at the specified register address, which will be an integer (int32).

Example:

-- Read the value of output register 1 and assign it to the variable regInt.
local regInt = GetOutputInt(1)

GetOutputFloat

Prototype:

GetOutputFloat(address)

Description:

Gets the float value at the specified output register address.

Required Parameters:

• address: Register address, valid range [0-23]

Returns:

The value at the specified register address, which will be a single-precision floating-point number (float).

Example:

-- Read the value of output register 2 and assign it to the variable regFloat.
local regFloat = GetOutputFloat(2)

SetOutputBool

Prototype:

SetOutputBool(address, value)

Description:

Sets the boolean value at the specified output register address.

Required Parameters:

• address: Register address, valid range [0-63]
• value: The value to be set, supports boolean or 0/1.

Example:

-- Set the value of output register 0 to false.
SetOutputBool(0, 0)

SetOutputInt

Prototype:

SetOutputInt(address, value)

Description:

Sets the integer value at the specified output register address.

Required Parameters:

• address: Register address, valid range [0-23]
• value: The value to be set, supports integer (int32).

Example:

-- Set the value of output register 1 to 123.
SetOutputInt(1, 123)

SetOutputFloat

Prototype:

SetOutputFloat(address, value)

Description:

Sets the float value at the specified output register address.

Required Parameters:

• address: Register address, valid range [0-23]
• value: The value to be set, supports single-precision floating-point numbers (float). Due to the storage mechanism of floating-point numbers (IEEE754), single-precision floating-point numbers can hold about 6 to 7 significant digits (regardless of the decimal point position). Values with significant digits greater than 6 may result in deviations when stored as single-precision floating-point numbers, and the more significant digits there are, the greater the potential deviation.

Example:

-- Set the value of output register 2 to 12.3.
SetOutputFloat(2, 12.3)
