Precautions for Handling
Intro-8 ME0384-3A
Precautions for Handling
1. Make sure to follow the usage condition, environment and specification range of the product.
In case it is not secured, it may cause a drop in performance or malfunction of the product.
2. Use the correct teaching tool.
Refer to the following item and use compatible tools for PC software and teaching pendant
usable for this controller.
[Refer to 4.1 Tools to Use]
3. Back up data in order to be prepared for a breakdown.
Non-volatile memory is used for backup memory of this controller. Registered position data and
parameters are written in this memory and backed up. Therefore, these data will normally not be
lost even if the power is turned off. However, be sure to save the latest data to enable a quick
recovery process in case this controller needs to be replaced with a substitute due to
breakdown, etc.
How to save
(1) Save to an external memory or a hard disk using PC software
(2) Record position table and parameters in writing
4. Perform initial operation setting.
This controller is compatible with 7 types of field network to support various applications.
Establish the settings considering the way of use at the startup.
[Refer to 1.2 Features Chapter 5 Operation]

Precautions for Handling
ME0394-1A Intro-9
5. Creation of sequence programs
When creating a sequence program, be careful of the following.
If exchanging data between devices with different scan time, the length of time required for a
reliable signal reading process is greater than the longer scan time. (In order to safely perform
the reading process on the PLC side, we recommend using a timer set value of at least twice
the longer scan time.)
●Operational image
As shown in the diagram, if exchanging data
between 2 devices with different scan time,
obviously the I/O timing will not match.
When the signal of this controller turns ON, there
is no guarantee that the PLC will read it
immediately.
In cases like this, in order to achieve reliable
reading, set the PLC side to read after a period
greater than the longer scan time has passed.
This also applies when the reading is performed
on the controller side.
On this occasion, make sure the safety factor of
the timer setting is 2 to 4 times or more of the
scan time.
As the timer is also processed within the scanning
process, setting below the scan time is
dangerous.
The example shown in the diagram indicates that
even if this controller performs output process
once every 1 ms, the PLC can only recognize
once every 20 ms.
The PLC only performs the output process once
every 20 ms, meaning that it keeps recognizing
the same output status for that period.
Also, if reading is performed while the other device is rewriting output, incorrect signals may be read
at times. Wait until the rewriting is completely finished (allow interval of 2 scans or more), then
perform reading. In terms of the output-side device, do not allow its output to change until the other
device finishes the reading. Additionally, an input constant is set for the input component to prevent
mistaken detection of noise, etc. so it only accepts signals that last more than a certain period of
time. It is necessary to add this period of time as well.

6. PLC timer setting
The PLC timer setting should not be at minimum set value.
If "1" is set, some PLCs turn ON somewhere between 0 and 100 ms with a 100 ms timer, or
between 0 and 10 ms with a 10 ms timer.
Consequently, the process which will be performed is the same as when a timer is not set,
which may lead to failures such as failing to position to a specified position No. in positioner
mode, etc.
The minimum set value of the 10 ms timer should be "2", and when required to set to 100 ms,
use the 10 ms timer and set it to "10".
7. External communication ports
The REC gateway unit has 2 types of communication port.
• SIO port (RS-485 round connector)
• USB port (USB mini-B connector)
Do not connect multiple ports and perform communication simultaneously.
This may result in following errors:
• Occurrence of communication error
• Occurrence of unpredictable operation
8. Caution in Use
Make sure to read the 5.3.2 Caution for REC System.
Failure in operation could cause damage on the products and equipment.

Precautions for PC connection to REC gateway unit grounded at positive terminal of 24 VDC power supply
Intro-12 ME0394-1A
If the gateway unit is grounded at the positive terminal of the 24V DC power supply, use an
SIO isolator (RCB-ISL-SIO) as shown in the diagram below when connecting a PC to the
SIO connector of the gateway unit.
If a PC is connected to the gateway unit without using an SIO isolator, the power will short-
circuit and cause the PC to malfunction.
Caution
●RS-232 conversion unit (RCB-CV-MW) cannot be used.
