# 1 Introduction

With the advent of IoT, more field devices are connecting to the Internet. Instead of being distributed at each field site, systems can be monitored and managed from a central control room. In this scenario, machine condition monitoring systems play a crucial role. Monitoring devices are typically deployed at the OT site, but by using an Ethernet-based data acquisition system (DAQ), machine conditions can be monitored remotely by IT staff.

The ADLINK MCM-204 is a standalone Ethernet DAQ that acquires vibration signals from a monitored machine and transforms this signal from raw data into filtered data. By capturing data such as FFT, power spectrum, overall value (OA), etc., with a standalone DAQ, the MCM-204 plays a critical role in pre-processing at the edge. Continuous high-volume data generated in the field can be converted to filtered data, significantly reducing its size. This in turn dramatically reduces network bandwidth traffic as well as the backend server’s computing burden.

The MCM-204 is designed for on-site process automation in the field. When recovering from a power failure, the system will automatically resume its previous running state. The MCM-204's compact size also makes it easy to install in the limited confines of an electrical control cabinet.

# 1.1 Features

 Standalone Ethernet DAQ for edge computing
 RESTful API reports machine conditions to IT system

# 2 Getting Started

# 2.1 Unpacking the MCM-204

Ensure that the following items are included in the package. If any items are missing, contact your sales representative for assistance.

 MCM-204
 DIN rail mount kit with 2x flat head screws
 Temperature sensor with 3 meter cable
 Quick Start Guide
 Optional accessories (if applicable):
 Wall mount kit with 4x pan head screws
 40W AC-DC adapter

![The image features a triangular warning symbol. It consists of a dark red (maroon) triangle pointing upwards, containing a large white exclamation point in its center. Directly below the triangle is the text 'WARNING' in black, uppercase letters.](.mcm-204-50-1z306-1000-10/fb526bb340a9a1b5997e940b067d4e6fe797dd76ef9da7f5a6622aa630863ce4.jpg)

Before unpacking, check the shipping carton for any damage. If the shipping carton and/or contents are damaged, inform your dealer immediately. Retain the shipping carton and packing materials for inspection. Obtain authorization from your dealer before returning any product to ADLINK.

# 2.2 Connecting to I/O

1 For analog input, plug in the accelerometer with a BNC type connector.
2. For digital input or output, insert the signal wires into the terminal block.
3. Use a CAT 5 type Ethernet cable to connect a host PC to one of the Ethernet ports on the top panel. To create a daisy chain of multiple MCM-204 devices, use the second Ethernet port to cascade them together. Cascading reduces the number of ports needed to connect devices.

If connecting MCM-204 devices in a daisy chain, only use a sequence configuration: do not use a ring configuration. A ring configuration will cause network communications to fail.

4. For temperature measurement, plug a two-pin temperature sensor connector into the front panel ports before attaching the temperature sensor to the target area to be measured.

# 2.3 Connecting/Disconnecting Power

1 Before turning on the power source, connect the positive and negative wires from a 9 to 30 VDC power source to the terminal block.
2. Turn on the power source. If the power was connected correctly, the front panel red PWR LED will light up.

If the MCM-204 needs to be shut down, turn off the power source.

To remove the power wires, use a flat head screwdriver to push the orange slots on the terminal block and then pull out the wires.

![The image displays a standard warning sign featuring a yellow triangle with a black border and a central black exclamation point. Below the triangle, the text 'CAUTION:' is printed in black capital letters.](.mcm-204-50-1z306-1000-10/563791a2d5967430d2aee263a7fb431682b859248cbf9d8a28c4f050d76cc3a7.jpg)

Ensure the power source is turned off before connecting or removing the power wires.

# 2.4 Checking Device Status

1 When power is supplied, the PWR LED will be red. The SYS LED will initially blink red, then turn to a steady red for about 35 seconds, then change to a steady green indicating the device has successfully booted up.
2. Log into the device’s web console for additional status information and configuration options. See “Web Console Login” on page 21.

# 2.5 Usage Scenarios

The MCM-204 is designed for distributed machine condition monitoring and can be used in many kinds of scenarios. Choose the most suitable scenario depending on the system infrastructure, data type, and frequency of data retrieval.

# 2.5.1 First-Time Configuration / Portable DAQ

Use the web console to configure device information, system settings, network settings, and test measurement analog input settings. For portable DAQ usage, the MCM-204 has a built-in dashboard to show the results of acquired data. The web-based console is also a convenient tool for users unfamiliar with DAQ behavior or programming. See “Web Console” on page 21.

# 2.5.2 Periodic Polling (REST API)

Many distributed machine condition monitoring applications acquire device status periodically, for example, every minute, or hourly. The MCM-204 retains captured data in the REST data format. Especially in IT systems, user applications frequently adopt REST APIs because they are intuitive. The MCM-204 emulates all functions supported by REST APIs, and the MCM-204 embedded middleware executes related operations and transfers the filtered data in JSON format. All queries from a REST command are handled by the MCM-204 and reply accordingly. See “DAQ Missions” on page 39.

# 2.5.3 Continuous Data (Streaming SDK)

Some applications need to acquire streaming data continuously. To transmit high volumes without data loss, raw data without any transformation is best. For users needing to access the DAQ library directly, the Streaming SDK is the proper method. By using the streaming API, all queried raw data may bypass the MCM-204’s middleware and route directly to the host PC via Ethernet. See “Continuous Data” on page 41.

# 2.5.4 Passive Data (TCP Socket)

For passively retrieving data, it is suitable to use a TCP socket with the MCM-204 in client mode. Whenever data is generated, the MCM-204 will be triggered to establish a TCP connection with the host PC and actively transmit the data. See “Web Console” on page 21.

This page intentionally left blank.

# 3 Web Console

This chapter describes how to use the built-in web console to configure the MCM-204 and view captured data.

# 3.1 Web Console Login

After the MCM-204 has been successfully powered on and a host PC has been connected to it, do one of the following: (1) set the PC’s network setting to either DHCP mode or link local mode; or (2) modify the PC’s IP address to be on the same network segment as the device (169.254.x.x). Next, open a web browser on the PC (Google Chrome is recommended) to access the web console via one of the following options.

# Option 1: IP Address

In the web browser’s address bar, enter the MCM-204’s IP address (e.g., http://169.254.1.1). The default network setting of the MCM-204 is Static IP mode with an IP address of 169.254.1.1.

# Option 2: Hostname

Connect the MCM-204 to a network component (switch/router) with DNS functionality, then enter the MCM-204’s hostname in the address bar of the host PC’s web browser, prefaced by http:// (e.g., http://mcm204-j801ns1001). A unique default hostname is generated for each MCM-204 device and can be found on the label of the box it was shipped in. The hostname can be changed within the web console.

After using either method, the web console will display within roughly 30 seconds, presenting the user with a login screen (see Figure 3-1 on the next page).

The default username is administrator and the default password is Adlink6166.

Trigger Source allows the data capture function to be triggered from a particular source via analog and digital triggers.

Repeat Interval is the interval between data captures, in milliseconds. Each data query consists of data capture via FPGA plus data filtering via MCU. The time required for data filtering may vary according to the complexity of the filtering algorithm.

Repeat Times is the total number of times the data is to be captured. For endlessly repeating data capture, set to 0.

![The image features a dark red triangular warning sign with a white exclamation point in the center. Below the triangle, the text 'WARNING:' is printed in bold, black capital letters.](.mcm-204-50-1z306-1000-10/df1838860cdc461a51590214237727f09471e596764a96887f425b09a7164415.jpg)

Warning! If you are using a customized algorithm as your Data Type, it is strongly recommended to set Repeat Times to 1 for the first attempt, then to 10 for a limited data capture test.

# 4 DAQ Missions

The MCM-204 supports various modes of operation that users can choose from to quickly integrate into their systems.

# 4.1 Usage Behaviors

IEPE sensors transmit raw data to the MCM-204 which can then be filtered to other kinds of data types that are more application appropriate, such as overall vibration values (ISO 10816) for mechanical vibration data. The overall vibration value data size is greatly reduced in comparison to raw data, so the backend server receives much less data for analysis. Data filtering is best suited to applications requiring continual information updates at a given time interval, such as every minute, which the user can then review periodically.

In contrast to data filtering, some applications, such as lab testing, require continuous raw data for analysis. However, continuous transmission of large amounts of raw data places a heavy burden on the backend server and takes up more network bandwidth. Evaluate your bandwidth and application requirements carefully in order to adopt the most suitable programming method for your needs.

There are three major usage behaviors: Periodic Polling, Continuous Data, and Passive Data. Choosing between them depends on how frequently data must be retrieved. Figure 4-1 on page 40 can serve as a guide for selecting the appropriate usage behavior for system integration based on polling data frequency.

For the periodic polling mode, MCM-204 provides a REST API and sample code in C#, Python, and JavaScript. Alternatively, for continuous data mode, MCM-204 provides a Streaming SDK and associated C/C++ sample code.

# 4.1.1 Web Console

The MCM-204 has a built-in, easy-to-use web console that implements all device functionalities. By logging into the web console through a connected host PC, users can see all of the device’s current settings, each feature it provides, and any vibration data it has collected.

# 4.1.2 Periodic Polling

A RESTful API is provided to facilitate periodic data polling. The REST document can be found on the web console’s menu bar.

![ADLINK\nMenu\nDevice: MCM-204 Account: administrator Role: admin\nSystem Information\nRestful API Doc](.mcm-204-50-1z306-1000-10/c33bdb9c22fb6f99e70ac3fd410f428b200b79250c5dbf295aacfe68a27b96d7.jpg)

Figure 4-2: RESTful API

Using this API, functionalities shown in the web console can be implemented in your own custom software. Function references and sample code in Python, JavaScript, and C# are available for download on the MCM-204 product web page:

www.adlinktech.com/Products/IoT\_solutions/Smart\_Factory/MCM-204

# 4.1.3 Continuous Data

To use continuous data mode, first install the Streaming SDK, available for download on the MCM-204 product web page:

www.adlinktech.com/Products/IoT\_solutions/Smart\_Factory/MCM-204

After installation, C/C++ sample code and function references can be found in the C:\ADLINK\MCM\MCM200 folder.

Before using the Streaming SDK, DDS must be enabled via the MCM-204 web console.

WARNING:

 When using DDS, the host server and MCM-204 must be deployed to the same network segment.
 The programming environment’s debug mode is inaccessible.
It is strongly recommended not to use the REST API for querying continuous data.

# 4.1.4 Passive Data

The conventional message exchange pattern of the MCM-204 for Periodic Polling and Continuous Data modes is request-response, with the MCM-204 serving as responder. After receiving a query from the host, the MCM-204 responds with the requested data. However, for some applications it’s desirable for the host server to passively wait for data from the client. In such cases, a TCP socket function can instruct the MCM-204 to automatically send data to the host server whenever data is generated. See “TCP Socket” on page 31.

# 4.2 Custom Filtering Algorithms

The MCM-204 offers flexible support options for custom filtering algorithms. Users can easily import their own domain-knowledge algorithms to the MCM-204. Custom filtering algorithms must be written in C or C++ and compiled under Linux.

Use the following steps to create a custom filtering algorithm.

1. Download and extract the Linux toolchain:
https://releases.linaro.org/components/toolchain/
binaries/6.2-2016.11/arm-linux-gnueabihf/
gcc-linaro-6.2.1-2016.11-x86\_64\_arm-linux-gnueabihf.tar.xz

2. Download CustomizedAlgo.zip from the MCM-204 web page and extract the CalStatistic (C++) and CalRMS (C) sample program folders.

https://www.adlinktech.com/Products/IoT\_solutions/ Smart\_Factory/MCM-204

3. Place the extracted CalRMS and Linux toolchain folders in the same file path.
