Precautions for Handling

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.
