Features

High-Speed Multi-Channel Capability

The table below provides reference information on the maximum number of measurable channels in relevant measurement intervals (when using Yokogawa's proprietary software):

High-Speed, Multi-Channel Capability

The relationship between measurement intervals and the number of channels largely depends on the performance of the PC. The actual performance may differ from that shown in the table.

<PC System Requirements>
CPU: Pentium 4 3.2 GHz; Memory: 1 GB; OS: Windows 2000; Hard disk: 160 GB
Communication interface: Ethernet 100Base-TX

Multi-Interval Measurement

Three types of measurement intervals can be used in a single system in various combinations. Measurement intervals are specified for each module. It is also possible to set different types of input modules to the same measurement interval or to set the same type of input modules to different measurement intervals. Twelve measurement intervals are available as userselectable options: 10 ms, 50 ms, 100 ms, 200 ms, 500 ms, 1 s, 2 s, 5 s, 10 s, 20 s, 30 s and 60 s. Please note, however, that measurement intervals of 10/50 ms cannot be set to the Medium-speed Universal Input Module (MX110-UNV-M10).
   
Examples of Setting Measurement Intervals

Examples of Setting Measurement Intervals Multi-interval systems can be flexibly built for each module as shown in the figure below. Three colors Tm Mx100 04 are used to indicate the three types of measurement intervals.

Monitor Window Using Yokogawa's Proprietary PC Software

Monitor Window Using Yokogawa's Proprietary PC Software The window shows measurement values by measurement intervals. Measurement can be performed while confirming rapidly-changing signals and slowly-changing signals simultaneously.

A: Measurement of sine waves at 0.5 Hz with a measurement interval of 100 ms
B: Measurement of sine waves at 8 Hz with a measurement interval of 10 ms
C: Measurement of sine waves at 1 Hz with a measurement interval of 50 ms

High Withstand Voltage (Reinforced Insulation)

Reinforced (double) insulation has been provided between the input terminals and the case to achieve a high withstand voltage of 600 Vrms/VDC (continuous). As shown below, each battery voltage can be measured even if the batteries are stacked to increase common-mode voltages.

High Breakdown Voltage

Noise Rejection (MX110-UNV-H04)

MX input modules employ integrating A/D converters with superior noise rejection performance. In particular, the MX110-UNV-H04 Four-Channel High-Speed Universal Input Module incorporates an integrating A/D converter for each input channel, thereby exhibiting strong noise rejection performance in high-speed measurement. Moreover, the digital filtering function is effective on noises that cannot be fully rejected even with integrating A/D converters. Time constants can be selected from 5 to 100 measurement interval times. Therefore, filtering can be applied according to the noise to be rejected.

Example of Noise Rejection

When the noise source in the left figure was applied to the MX, the result in the right figure was obtained. High-speed measurement can be stably performed even in noisy environments.

System Configuration

Connection between a single MX unit and a single PC (measurement of 24 channels/10 ms or 60 channels/100 ms)

One MX unit enables data acquisition on up to 24 channels at a measurement interval of 10 ms, or up to 60 channels at a measurement interval of 100 ms (six modules installed in both cases).

 System Configuration Setting up the System
The MX and PC are connected via a hub and a straight Ethernet cable. Alternatively, they can be connected using a cross cable alone, without using the hub
 Input signal:
    DC voltageThermocuple,
    RTD,Digital input (Mixed input possible)		 PC Software
In a one-to-one connection, the MX100 standard software included with the main module facilitates easy building of data acquisition environments.
One MX unit consists of a combination of a main module, input/output modules, and a base plate. This configuration centers on the main module.

    Digital output

Connection between multiple MX units and a single PC

For measurement of up to 1,200 channels and the use of MXLOGGER

Example of a system with multiple MX units:

Example of a system with multiple MX units Setting up the System
The MX units and the PC are connected by means of a hub and straight Ethernet cables.

PC Software
Acquisition of data from multiple MX units is well-supported by Yokogawa’s software “MXLOGGER” (optional). MXLOGGER enables data acquisitions of up to 20 MX units (one unit has inputs of up to 60 channels, or 1,200 channels on 20 units).

Please note that the shortest measurement interval of MXLOGGER depends on the system's total number of channels and the PC's performance. For guidelines on measurement intervals and the number of channels, please visit….

If users wish to create their own data acquisition software, there is no limit to the number of MX units that can be integrated with a single PC software element. Please note, however, that if conditions with heavy loads (such as short measurement intervals with many units) are set to the PC and its software, data will not be acquired in time and some data may be lost.

Hardware Configuration

ModuleThe MX is designed to enable desired measurement environments by combining three elements: the main module, input/output modules, and a base plate.
The assembled unit can be utilized on the desktop as-is (the modules have legs). Please note that DIN rails are used for rack-mounting.		 Hardware Configuration

Main Module (MX100)

The main module is the engine that controls data acquisition. It is equipped with a power supply, an Ethernet port, and a CompactFlash card slot. One main module can accommodate up to six input/output modules. The user can choose up to six moduels of any type.

Main Module (MX100)
Ethernet port:

For communication with the PC. Automatic recognition of 100Base-TX or 10Base-T

CF (CompactFlash) Card Slot:

CF
With the CF Card, measured data is saved to the card if communication with the PC is interrupted. Since the card provides data backup, you do not have to worry about the possible loss of data even if the MX is configured for PC-based measurement.
