  1. WinCC analog scaling

    loonx posted a topic in Siemens

    For analog display, i would like to do the scaling on WinCC instead of on PLC. Example: Analog raw value 0-4000 (4-20mA) Scaled to 0-100% for display on WinCC. How to do it??
  2. I m using a Modicon (Multimode) Fiber Optic Repeater to link up the Main CPU Rack to the remote I/O rack. Due to my client's requirement we need to use single-mode FO for field cabling. Currently i m sourcing for a third party multimode to singlemode converter that is compatible with Modicon 490NRP954. I have tested a few converter but failed. One issue that caught my attention is the wavelength. According to Modicon's manual, the wavelength from the Repeater is 820nm. But most converter i m using supports only 850nm & 1300nm. I m not really familiar with fibre optic, can anyone help??
