Unlike a typical computer, a PLC can only be used to handle programming language for machine automation. 409.60 provides the requirements for bonding (see Art. Both PC-based or PLC-based solutions are eligible for some applications, however the major constraint that proves detrimental is the cost associated with these solutions. PC control can often satisfy both the need for fast sophisticated data handling, along with process or sequential functions for control. Detailed troubleshooting after an alarm in the control room means the operator has to go outside to the UCP on the local equipment skid. $ď A/ !z Hl *ad�``D"�3��0 Ȼ� %%EOF No hard and fast definitions… But a “panel” usually implies indications. AC drives accurately control torque, smoothly handle increased load and provide numerous custom control and configuration operating modes. LOCAL CONTROL PANEL . The devices that are connected to the panel are varying, but in typical it is a transmitter, solenoid, valve actuator, etc. Don't ground this panel. A distinct plant is handled by each controller.
