1. Introduction
1.1 Overview
CANopen is one kind of the network protocols based on CAN bus and
mainly used for embedded system, such as industrial machine control,
vehicle control system, factory automation, medical equipments control,
remote data acquisition, environment monitoring and package machines
control. The CAN-2084C is a CANopen slave which follows the CiA 301
version 4.02. The CAN-2084C is a 4/8-channel Counter/Frequency
module that provides “Up Counter”, "Frequency”, “Up/Down Counter”,
“Dir/Pulse Counter” and “A/B Phase Counter” modes. It provides a variety
of measurement applications, such as measuring a number of time-
related quantities, counting events or totalizing and monitoring position
with quadrature encoders. In addition, a digital filter is used to eliminate
the effects of noise. Users can obtain those data or configure the CAN-
2084C via the standard CANopen protocol. In order to be fully compatible
with other CANopen devices, the CAN-2084C has passed the validation
of the CiA CANopen Conformance Test tool. Therefore, it is very easy to
integrate the CAN-2084C with the standard CANopen master by applying
the EDS file. Combining with the CANopen masters of ICP DAS, you can
quickly build a CANopen network to approach your requirements.

2.2 Node ID & Baud Rate Rotary Switch
The rotary switches for node ID configure the node ID of the CAN-2084C
module. These two switches are for the tens digit and the units digit of node ID. The
node ID value of this demo picture is 32.
The rotary switch for baud rate handles the CAN baud rate of the CAN-
2084C module. The relationship between the rotary switch value and the practical
baud rate is presented in the following table.

The CAN-2084C needs a 10V~30VDC power supply. Under a normal
connection, a good power supply and a correct voltage selection, as the unit it turned
on, the LED will light up in red.
Run LED
The Run LED indicates the CANopen operation state. The description of the
LED state is shown below. About the details, please refer to the section 2.3.1 of the

2.5 Wire Connection
The CAN-2084C has two kind of inputs, isolated and non-isolated (TTL) for different
input signals. Users can switch jumper setting on the CAN-2084C board for
appropriate signal. These jumpers are located within JP1~JP8. The jumper settings
are listed in the following table. The isolated input is set by default.

CAN-2084C User’s Manual (Version 1.00, Sep/2018) ------------- 13
2.6 Input Signal Model
Isolated Input (XOR=0)
The operational logic applied on CAN-2084C modules is a falling edge trigger.
(Normal High and Active Low) The external signal is input into a CAN-2084C
module through the isolation mechanism, with the signal being reversed from the
external signal. This internal signal is the suggested waveform, as the XOR
operation (XOR=0) doesn’t need to be executed.
The solution is shown below.
TTL Input (XOR=1)
When an external TTL signal is input into a CAN-2084C module through the TTL
mechanism, the signal will be the same as the external signal. This internal signal
isn’t the recommended waveform as the exclusive OR (XOR=1) operation must be
executed to invert the waveform.
The solution is shown below

2.7 Digital Low Pass Filter
The CAN-2084C includes three independent 2nd-order digital noise filters that can be
used to remove noise, and are implemented as follows:
The Low Pass Filter can be set to either enabled or disabled. The width of the
Low Pass Filter is programmable and can be set within a range from 1 µs to
32767 µs.
The Low Pass Filter can be applied to all working modes, both counter and
frequency.
All three Low Pass Filters are disabled by default when the module is shipped.

CAN-2084C User’s Manual (Version 1.00, Sep/2018) ------------- 15
Refer to the following table for details of how to set the Low Pass Filter:
An example is illustrated in the following figure:
In this example, H < T and the high width of the input signal < the period of the filtering
clock, and so the signal will be filtered.
Supposed T = 1 ms, that is the filtering clock has a frequency of 1 kHz. Now, if the
duty cycle of the input signal is 50%, that is the high width is equal to the low width,
then:
H < T ➙H < 1 ms
➙input signal period < 2 ms (duty cycle = 50%)
➙input frequency > 500 Hz,
Consequently, the input signal will be filtered.
Now, if the duty cycle of the input signal is 25%, that is the low width is three
times the high width, then:
H < T ➙H < 1 ms
➙Input signal period < 4 ms (duty cycle = 25%)
➙Input frequency > 250 Hz,
Consequently, the input signal will be filtered.
Similarly, the maximum period of the filtering clock can be calculated to allow the input
signal to be passed using the formula H > 2T.

2.8 Counter Mode
2.8.1 Mode 0: Dir/Pulse Counting(Bi-direction)
When InB0 is used as Dir:
If InB0 is Low, counter will be increased by one for every falling edge of InA0.
If InB0 is High, counter will be decreased by one for every falling edge of InA0.
2.8.2 Mode 1: Up/Down Counting
When InA0 is used as an UP_clock and InB0 is used as a DOWN_clock, counter_0
will be increased by one for every falling edge of InA0 and decreased by one for every
falling edge of InB0.

CAN-2084C User’s Manual (Version 1.00, Sep/2018) ------------- 17
2.8.3 Mode 2: Frequency Mode
We calculate frequency of a certain channel by how many counts in a period of time.
There are two modes: Normal Mode and High Speed Mode for measurement
frequency
Normal Mode:
Normal Mode will read 1 pulse, this pulse will be calculated frequency value.
High Speed Mode:
High Speed Mode will read 11 pulses to calculate average value of those 11
pluses.
High Speed Mode will be more accuracy than Normal mode for measurement
Frequency. We suggest using High Speed Mode if measurement frequency is more
than 10k Hz.

CAN-2084C User’s Manual (Version 1.00, Sep/2018) ------------- 18
2.8.4 Mode 3: Up Counting
Counter_0 will be incremented by one for every falling edge of InA0
2.8.5 Mode 4: Quadrant Counting(A/B Phase)
When InA0 is used as an A signal and InB0 is used as a B signal:
Counter_0 will be increased by one when the InA0 phase leads by 90 degrees to
InB0.
Counter_0 will be decreased by one when the InA0 phase lags by 90 degrees to
InB0.
