WindO/I-NV4 User’s Manual
• When sending and receiving data with an external device from PLC programming software using the Pass-through
function, MICRO/I Device Link Communication and Pass-through function communication are performed at the
same time, so the data transfer speed of each will decrease.
In this case, if Device Link Communication between the MICRO/I and the external device is stopped by the Pass-
through Tool, the data transfer speed of downloading or uploading the PLC program via MICRO/I will be improved.
However, "Communication Error" will be displayed on the MICRO/I screen.
• Do not use communication with WindO/I-NV4 and Programming software at the same time.
• If the communication via Pass-through fails, change the settings such as Baud Rate, Timeout, Transfer Mode etc on
PLC programming software.
• If one of the following problems occurs while using the Pass-through function and a communication error is
displayed, turn power off and on to the MICRO/I again.
- The communication cable between the computer and MICRO/I was disconnected after stopping communication
of the MICRO/I and the external device using the Pass-through Tool.
- The computer was forcibly shut down due to a power loss or other problem
• The Pass-through function can only use one of "External Device Communication 1" through "External Device
Communication 4".
