  • Page 18: Features

    Features (1) Available flexible system configuration Adopting the connection block type enables the combination of the main module and extension module. Because various extension modules can be connected, a flexible configuration can be achieved. In addition a poor contact of the extension module can be found promptly because the main module always monitors the connection status of the extension module.
  • Page 19 CHAPTER 1 D/A CONVERTER MODULE (6) Error detection and monitoring available When a digital value exceeds the range set in advance, an alert is detected. Thus, an error of digital value can be monitored and outputs of a digital value can be limited. (7) Output available without influence from the sequence scan or link scan An error status or alert status can be output from the extension output module by using the external signal assignment function when an error or alert occurs.
  • Page 20 (9) Easy module replacement Because the 2-piece structure is adopted for the terminal block for module power supply and FG and terminal block for analog output signals, the module can be replaced with the wire connected. In addition, because the terminal block for analog output signals is the lift-up structure, the terminal block can be lifted only by loosening the terminal block mounting screw to be removed easily.
