Curtis 1356/1356P CAN Expansion Module Manual, Rev. A

Voltage Analog Inputs
e 1356 /1356P has ve analog inputs that are scaled to read 0 – 15 volts. e
analog channels are read by a 12-bit ADC, resulting in about 3.66 millivolt
resolution. Independently adjustable lters 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
e ve 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. us, these inputs can be used with analog sensors
to detect conditions like over/under pressure, high/low level points, etc.
Encoder Interface
e 1356 /1356P has one quadrature encoder input, which shares with the
Analog 4–5 pins. e 1356 /1356P can detect an open fault on the encoder
input wire.
CAN Interface
e 1356 /1356P is CANopen compliant, responding to the standard NMT,
PDO, and SDO communications as well as the DS301-required identity and
standard objects. e Curtis CANopen extensions allow additional features,
such as OEM and User default congurations and time-stamped fault logging.
PDO Dynamic Mapping
e 1356 /1356P can receive two PDOs and respond with two PDOs. ese
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
e 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
e 1356 has two fault LEDs (red and yellow) to clearly ash the fault code.
Both the 1356 and the 1356P can drive a single remote LED via the serial
port, to ash 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.
