Functions

public pure elemental function dm_modbus_register_has_scale(register) result(has)

Returns .true. if register attribute scale is greater 1.

Arguments

Type IntentOptional Attributes Name
type(modbus_register_type), intent(in) :: register

Modbus register type.

Return Value logical

public pure elemental function dm_modbus_register_is_valid(register) result(valid)

Returns .true. if Modbus register type is valid.

Arguments

Type IntentOptional Attributes Name
type(modbus_register_type), intent(in) :: register

Modbus register type.

Return Value logical


Subroutines

public subroutine dm_modbus_register_out(register, unit)

Outputs Modbus register type.

Arguments

Arguments

Type IntentOptional Attributes Name
character(len=*), intent(in) :: string

Input string.
type(modbus_register_type), intent(out) :: register

Modbus register type.
integer, intent(out), optional :: error

Error code.

public pure elemental subroutine dm_modbus_register_scale(register, value)

Scales given value by scale denominator in register. For example, if attribute scale is set to 10, the routine will device value by 10. If scale is 0 or 1, the value will not be modified.
