How can I communicate with RS232 on RTtarget

[kzr_kratos]

Hello,

Unfortunately I am not very experienced using Labview and need your help.

I am trying to commuicate with an massflowcontroler (MFC) with cRIO9074 respectively cRIO9870.

It is working well using VISA, but only if my VI is running on hostPC. Now I tried to copy this into my RTtargetVI and couldn´t find the COM Port using "VISA configure serial port".

Do I need to install driver, so it is working on real-time target?

kzr_kratos,

Make sure that "NI-Serial 9870 and 9871 Scan Engine Support" is installed on the cRIO-9074.
