• Rapid temperature fluctuations (causing condensation)
• Relative humidity outside the range of 35 to 85%
• Presence of corrosive or flammable gases
• Presence of dust, salt, or iron particles
• Direct vibration or shock
• Reflection of intense light (such as other laser beams or electric arc-welding
machines)
• Direct sunlight or near heaters
• Water, oil, or chemical fumes or spray
• Strong magnetic or electric field
(2) Power Supply and Wiring
• When using a commercially available switching regulator, make sure that the FG ter-

Features of the Data Storage Unit
Features of the Data Storage Unit
The Data Storage Unit is an exclusive data collection unit. It gets measurement data from
Sensor Controllers or Multi-Controllers while they are still installed at the site, and saves
that data to Memory Card (CompactFlash). The Data Storage Unit shares the high
reliability of the ZS Series, and reliably collects data from on-site devices through simple
operation. Data saved on Memory Card can be easily loaded to a personal computer so
that collected data can be easily analyzed and operated on.
(1) Optimum Data Logging
A wide range of logging trigger functions are available, allowing you to save only the
valid data you require out of the immense volume of data during operation.
Example:
• External input-driven trigger
• Button entry-driven trigger
• Measurement value change-driven self trigger
• Judgment value-driven trigger
• Time-driven trigger
(2) Logging of Multi-point Controller Information and Calculation Information Sup-
ported
Data can be collected from up to nine Sensor Controllers. Calculation result data can
also be collected linked to the Multi-Controller.

(3) USB Connection
The Data Storage Unit is provided with a USB port (compliant with Full-Speed USB2.0
specifications) as standard. This means that the settings on the Data Storage Unit can
be changed on a personal computer or other extern device using the OMRON propri-
etary communication protocol CompoWay/F or non-procedural protocol. For details on
command formats, refer to the “Communication Command Reference” (provided sepa-
rately).

●Data can be collected whenever you want.
Data can be collected at any timing or by trigger conditions.
<by external input>
Measured values when the workpiece is
at the specified position are batch-acquired.
<by button input>
Measured values in a certain period are acquired
continuously.

<self trigger by change in state of measured value>
The data of a period, during which the measured
values of the workpiece are at a specified value or
less (or more), is acquired continuously.

A delay can be set to the logging start trigger. For example, in the case of logging by judgment
result, the data before a defect (NG) occurred can be saved by setting a minus delay.
●High-speed logging/extended logging can be selected.
The Data Storage Unit allows you to adapt to instances where you may want to confirm
whether data has been saved and detected correctly at high speed, for example, in test
verifications, or where you may want to collect data periodically over an extended
period for quality assurance reasons.
To save data at high speed, use the “one-shot mode”.
Sampling settings (one-shot mode) p.3-26
To log data over an extended period, use the “repeat mode”.
Sampling settings (repeat mode) p.3-26
●Logging data can be easily analyzed.
The Data Storage Unit is bundled with analysis software with programmed Excel mac-
ros.This software is useful in performing analyses after logging data is imported to a
personal computer.
