I have a machine which runs not in PLC may be PCB board or Embedded (i dont know excatly) which is operating in DOS. From the control panel, there are four RS232 port connected to the CPU. I need to get the data of the machine and calculate the OEE. Can I use a RS232 splitter and connect to RS232 to Ethernet converter which leads to the Ignition Server. I would like to know,if i do so, will i able to get all the individual data of the machine so that i could find the OEE of the machine.
