Relay
1 The Analog Output microblock uses the Min and Max values to linearly translate its EIKON
LogicBuilder wire value into a physical output signal (Volt, mA, or psi) sent from the Room
Controller to an actuator. For example, set Min to 0 and Max to 100 for an Analog Output
microblock that receives a 0 to 100% open signal from a PID microblock and that controls a 0–
10 Vdc actuator so that when the PID signal is 100%, the Room Controller output is 10 Vdc.
Similarly, when the PID signal is 50%, the Room Controller output is 5 Vdc.

Resolution values

Resolution is not particular to a type of input or output, but the driver handles analog and
digital (binary) inputs and outputs differently. To set these values appropriately, you
should understand how the driver uses them.

Notes
The driver truncates the microblock's present value according to the
resolution.
EXAMPLE If the calculated present value is 13.789 and you set the
Resolution to 0.1, the control program uses 13.7 for any calculations
downstream from the microblock.
The driver truncates the wire input value to the microblock before
performing any scaling calculations.
EXAMPLE If the wire input value is 13.789 and you set the
Resolution to 0.1, the microblock uses 13.7 for any scaling
calculations.
