I want to study the possibility of the following case:

1. I want to running a ignition Client App on a desktop that get the data from my company ERP, such as the length of the product
2. This desktop have a com port that can be use for rs232
3. PLC side also have the rs232 module  
**My question is whether that is possible let the ignition client send the data(Length such as 192.345) to the plc by means of the Com Port?**  
Perhaps you will ask , siemens plc can connect to the opc-ua , why you need use rs 232, because my factory have 3 these machine , every machine have different IP, and it’s position is very hard to connect to ignition’s network. My desktop PC can use wireless to get the data and if i install only 1 rs232 can send the length data , that will be the most convenient

I can’t see why not, Ignition has a bunch of serial scripting functions that can help you.
