11.5. BCD INPUT
An available option with the 2704 is the Binary Coded Decimal (BCD) function block. This
feature is normally used to select a program number by using panel mounted BCD decade
switches.
11.5.1. Main Features
Calculation of BCD Value: The function calculates a BCD value dependant upon the state
of the inputs. Unconnected inputs are detected as off. This value is available as a wireable
parameter.
Calculation of BCD Value: The function calculates a decimal value dependant upon the
state of the inputs. Unconnected inputs are detected as off. This value is available as a
wireable parameter.
Digit 1 Output: The function calculates the first decade BCD value dependant on the state
of inputs 1 to 4. Unconnected inputs are detected as off. This value is available as a wireable
parameter.
Digit 2 Output: The function calculates the second decade BCD value dependant on the
state of inputs 5 to 8. Unconnected inputs are detected as off. This value is available as a
wireable parameter.
