Problem Summary:
The RT application is running in cRIO already but we need to publish all the measurements in application over MODBUS protocol. I created MODBUS mapping by using Labview DSC module.
In cRIO side, I did everything regarding tutorials and instructions but I cannot read the register 0001 at MODBUS Master at laptop side. I only suspicious about the adapters I used while converting RS 232 port - RS 458 – USB. You can find the schematic of convertings. If you have a feasible converter or adapter suggestion for my application or do you have any another solution please let me know, I will be so appreciated.
Hardware:
- Crio 9066
- Null Modem, ( not straight) serial cable
- USB to RS485/422 Converter
- Regular RS 232-USB converter (My laptop doesnt have RS 232 ports)
- Laptop
Software
- Labview 17 Professional
- Labview 17 DSC Module
- Labview 17 RT Module
