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.

Frequency
1 Hz ~ (typically) 250 kHz for both counter and frequency mode, where 250 kHz is calculated as follows:
supposed that the duty cycle = 50%, by referring to the Minimum Pulse Duration of the High Level, the pulse
period will be 2 μs x 2 = 4 μs, which is 250 kHz as a maximum.
Maximum Frequency:
Refer to the Minimum Pulse Duration of the High Level, the maximum frequency is highly affected by the duty
cycle
Frequency Accuracy = ±0.4%

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.
