To use the Pass-Through function, use a Host I/F Driver that supports the Pass-Through function, and select the “Enable
Pass-Through” checkbox on [Configuration] - [System Setup] - [Project] - [Host I/F Driver] on the WindO/I-NV2.
3.1 Settings Pass-Through
The settings for the Pass-Through function can be changed from the WindO/I-NV2 or System Menu of the MICRO/I.
Use a host I/F driver that supports the Pass-Through operation and follow the procedure below.
• Enabling the Pass-Through Function from the WindO/I-NV2
Select [Configuration] - [System Setup] - [Project] - [Host I/F Driver], and select the “Use the Pass-Through
function” checkbox to enable the Pass-Through function.
• Enabling the Pass-Through Function from the MICRO/I System Menu
Select [Initial Setting] - [Host I/F Driver] - [Pass-Through Setting], and select “Enable” for the “Pass-Through
Setting” setting to enable the Pass-Through function.
3.2 The Pass-Through Preference Function
When transferring data from a computer to PLC using the Pass-Through function, the data transmission speed of the
computer and PLC is lower, because the transmission is performed simultaneously with the PLC-link communication of
the MICRO/I.
In such a case, setting as follows will improve the data transmission speed from the computer. In that case,
MICRO/I prioritizes the sent and received data from the computer, an error message “Host Communication Error” may
appear on the MICRO/I because the MICRO/I is out of PLC-link communication with PLC for the meantime.
