Block Type Description Graphic Form
8DO Eight Digital Outputs - Provides write access to any physical
digital output. Provides a digital status from the algorithms
and functions to physical logic output hardware. Each block
output requires a module and channel number during
configuration. The output status may be inverted.
FI Frequency Inputs - reads a single frequency channel from a
pulse-frequency-input module. It scales inputs from the
module to user-configured engineering units per unit time.
The function is used for measuring speed and flow rate. The
frequency high and low limits are sent to the module and the
module will respond with FAIL or the frequency input value.
PI
Pulse Inputs - reads a single input channel from a pulse-
frequency-input module. It scales inputs from the module to
user-configured engineering units corresponding to
accumulated pulses. The scaling typically represents a
quantity. The preset values, reset, preset action, hold and
clear flags are sent to the module and the module will
respond with FAIL, counter overflow indicator (OVFL), preset
indicator (PREI) and accumulated pulse counts.
2AND 2 Input AND - Boolean logic function turns digital output ON if
both inputs are ON, otherwise output is OFF.
Individual inputs may be inverted.
4AND 4 Input AND - Boolean logic function turns digital output ON if
all inputs are ON, otherwise output is OFF.
Individual inputs may be inverted.
8AND
8 Input AND - Boolean logic function turns digital output ON if
all inputs are ON, otherwise output is OFF.
Individual inputs may be inverted.
