  • Page 9: Introduction

    THE G4LC32 MODEL 200 PROCESSOR The G4LC32 Model 200 Processor is a local processing unit designed to be used in a Mistic Model 200 System. A Mistic system is the combination of a powerful industrial microcomputer, highly intelligent I/O, an amazing new control language, and a better idea for industrial packaging.
  • Page 10 The advantage of local I/O is speed (1.4 MHz, ~1.5 Mbps). The disadvantage is that the total bus length is limited to 200 feet. As many as 139 local I/O units can be connected to one G4LC32. You scan mix and match both digital and analog I/O units, as needed by your application.

    G4LC32 Front Panel Processor Status LEDs At the top of the G4LC32 front panel are three LED status indicators. Their function is as follows: POWER The red POWER LED comes on whenever 5 VDC power to the G4LC32 is above 4.85 VDC.

  • Page 16: Lcd Display

    During SETUP, the display is used to prompt you to enter the setup parameters from the keyboard. If you are running Cyrano 200 or OptoControl and you have downloaded the terminal task to the G4LC32, then the display is used to show parameters from your application’s program, such as the value of a variable, the status of an I/O point, etc.

  • Page 17: Messages

    In this case the keyboard is only used to enter setup parameters for the G4LC32. See the section on Front Panel Setup for the use of keyboard and display to enter and/or change setup parameters.

  • Page 18: Communication Status Leds

    This red LED is ON whenever there is communication on the ARCNET Bus and the ACTIVE G4LC32 is an active node. FRONT PANEL SETUP You can use the front panel display and keyboard to perform a setup for the G4LC32. Setup lets you view or change the following functions: Host port designation. Communication protocol.
