Hi,
I have a Siemens S5 135U with 928B processor. It has 2 serial ports, 1 for programming (used frequently) and another for HMI (current use is for OEM HMI). Problem is I want to add another HMI package to the PLC as the existing OEM one that we have cannot be moified.
Can I 'split' the serial ? Is there a card that can be bought for more serial or Ethernet comms?
New HMI will be RSView via KEPServer
Any help appreciated....
