Delta’s AC motor drives are able to efficiently control motor speed, improve machine automation and save energy. Cost The control panel is just the door in front of the control cabinet - when this door has buttons and/or touchscreens for operating. Although its title is “grounding,” Sec. The controller may be PLC, DCS, relay or some other type. The automation and control problems of today are multi-dimensional and can be solved in more than one manner. Which are shown in below figure. Control panel consists of a controller. Generally the motor feeder have inputs from field (local control panel) & PLC also. The functionality of the PLC has evolved over the years to include sequential relay control, motion control, process control, distributed control systems and networking. Control Methods: PLC vs Relay Logic Today’s PLC’s (programmable logic controllers) are cheaper and more flexible than ever before. hޔR�j�0�=���.�.��`��I�IC�²�W]���H��3v�MJ)F��3:3���3��r�q�$��^�ue'w. 115 0 obj <> endobj Various standards have to be observed for the construction of control panels for machinery. j�0�{X|�=ӈnq%� ӓ�En{���j�E��p;w���� �.=wz�-'zf������e�?��2��V�������d�\g�l&R Company Profile SITES with over 20 years experience, enjoys an international reputation for supplying control panels, PLC, BMS and pneumatic control systems. Preventative maintenance indicators of insulation resistance to indicate when pump windings require service. Grounding. h�b```"6�K� ���� 3. Pump efficiency calculations (combination of power monitoring and flow measurements). For the most part, the PLC/DCS split still follows this historical pattern. A PLC is a computer specially designed to operate reliably under harsh industrial environments – such as extreme temperatures, wet, dry, and/or dusty conditions. 3rd Party Safety Certification = UL508A (cULus) Short Circuit Current Rating … Advantages Still, some OEM’s and system builders prefer relay logic for their electrical controls – and in some cases, this may be justified. You could also substitute for 'operator panel'. Each H-O-A device occupies 3 bits of PLC data memory. Stuart G. McCrady, in Designing SCADA Application Software, 2013. These factors include, but aren’t limited to, past experience with each platform, price, the level of local support, and anticipated future growth and changes. The local control panel ’s selector switch must again be set to ‘Auto’ or ‘Remote’ so that the SCADA system has control. Programmable Logic Control (PLC) is a solid-state computerized industrial controller that performs software logic by using i/o, CPU, memory. The four basics steps in PLC operation are: Figure 5 below shows a schematic diagram for a PLC based motor control system, similar to the previous motor control example. That is, a PLC consists of hardware and software. Such systems can range in size from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems with many thousands of field connections. Hasil pengujian sistem yang telah dilakukan menujukan bahwa LCP dapat memonitor pembentukan rute di lapangan.

A small sump pump system is another example where local control on-board a VFD can provide the required functionality. 7.5.4 Remote Automatic Control Mode. PLC vs. DCS: DCS (Distributed Control System) is a CONTROL SYSTEM that operates with multiple controllers and coordinates all controller’s job. A common PLC application is the speed control of AC motors with variable speed (VS) drives. But, it does tend to become more complex. Control panel works based on the PLC /DCS program or the relay logic. AC drives accurately control torque, smoothly handle increased load and provide numerous custom control and configuration operating modes. The typical component inside the panel including but not limited to PLC (with all necessary module), AC to DC power supply, interposing relay, local HMI, etc. Instead, it uses an electronic controller and a software program to interface the inputs of the controlled system with the outputs. An instruction that draws attention to the risk of the product, process or surroundings. However, across Australian and U.S. water and wastewater municipalities, a large (and ever-increasing) number of authorities are specifying pump controllers even where a PLC-based remote terminal unit (RTU) already exists in the panel. This figure shows the E-stop wired to cutoff power to all of the devices in the circuit, including the PLC. PLCs operate in a repeating loop once the user determines the inputs and outputs. It allows the operator to force an item on, force it off or let it operate automatically. PLC-Based Controls. This is why we recommend that a risk analysis be carried out. A distinct plant is handled by each controller.
