Description
Eight Analog Inputs connect to eight DeltaV 4-20mA AI CHARMs – termination assembly model number FBM201 / P0916AA. Eight *Thermocouple/mV Analog Inputs connect to eight DeltaV Thermocouple/mV CHARMs – termination assembly model number FBM202 / P0916AC. Eight RTD Pt/Ni 2 or 3-wire Analog Inputs connect to eight DeltaV RTD CHARMs – termination assembly model number FBM203 / P0916AE. Four Analog Inputs connect to four DeltaV 4-20mA AI CHARMs– termination assembly model numbers FBM204 / P0916AG and FBM205 / P0916AJ. Fourteen *Thermocouple/mV Analog Inputs connect to fourteen DeltaV Thermocouple/mV CHARMs – termination assembly model number FBM212 / P0916BV. Note: *Emerson recommends re-wiring Thermocouple signals directly to DeltaV AI-T/C solutions.
When choosing a PLC, the cost performance ratio should be considered. When considering economy, factors such as scalability, operability, and input-output ratio of the application should be considered simultaneously to compare and balance, and ultimately select a more satisfactory product.
The number of input and output points has a direct impact on the price. Each additional input/output card requires an additional fee. When the number of points increases to a certain value, the corresponding memory capacity, rack, motherboard, etc. also need to increase accordingly. Therefore, the increase in points has an impact on CPU selection, memory capacity, control function range, and other choices. When estimating and selecting, full consideration should be given to ensure a reasonable performance price ratio for the entire control system.
When designing a PLC system, the first step is to determine the control scheme, and the next step is to select the PLC engineering design. The characteristics and application requirements of the process flow are the main basis for design and selection. The PLC and related equipment should be integrated and standardized, and selected based on the principle of easy integration with industrial control systems and easy expansion of their functions. The selected PLC should be a mature and reliable system with operational performance in relevant industrial fields. The system hardware, software configuration, and functions of the PLC should be suitable for the device scale and control requirements. Familiarity with programmable controllers, functional diagrams, and related programming languages is beneficial for shortening programming time. Therefore, when selecting and estimating engineering design, it is necessary to analyze the characteristics and control requirements of the process in detail, clarify the control tasks and scope, and determine the required operations and actions. Then, based on the control requirements, estimate the number of input and output points, required memory capacity, determine the functions of the PLC, external device characteristics, etc, Finally, choose a PLC with a high cost performance ratio and design the corresponding control system.
