Voltage Analog Inputs
The 1356 /1356P has five analog inputs that are scaled to read 0 – 15 volts. The
analog channels are read by a 12-bit ADC, resulting in about 3.66 millivolt
resolution. Independently adjustable filters ensure a smooth signal.
Resistive Sensor Inputs
Each analog input can be used with resistive sensors, such as RTDs (Resistive
Temperature Devices).
Virtual Digital Inputs
The five analog inputs are also sensed and decoded as if they were digital inputs.
A unique feature of these digital inputs is that the active high/low thresholds are
completely programmable. Thus, these inputs can be used with analog sensors
to detect conditions like over/under pressure, high/low level points, etc.
Encoder Interface
The 1356 /1356P has one quadrature encoder input, which shares with the
Analog 4–5 pins. The 1356 /1356P can detect an open fault on the encoder
input wire.
CAN Interface
The 1356 /1356P is CANopen compliant, responding to the standard NMT,
PDO, and SDO communications as well as the DS301-required identity and
standard objects. The Curtis CANopen extensions allow additional features,
such as OEM and User default configurations and time-stamped fault logging.
PDO Dynamic Mapping
The 1356 /1356P can receive two PDOs and respond with two PDOs. These
PDOs use dynamic mapping. All programmable parameters and viewable values
within the 1356 /1356P are accessible by SDOs or with a Curtis programmer.
Online Update
The 1356 /1356P has the ability to update its software through the serial port
(with Curtis 1309USB) or through the CANopen interface (with Peak-CAN
tools), using existing Curtis PC software tools.
Status LEDs
The 1356 has two fault LEDs (red and yellow) to clearly flash the fault code.
Both the 1356 and the 1356P can drive a single remote LED via the serial
port, to flash the fault code.
Familiarity with your Curtis 1356 /1356P module will help you install and operate
it properly. We encourage you to read this manual carefully. If you have questions,
please contact the Curtis office nearest you.
