This calculator determines the number of input/output modules required for a Programmable Logic Controller (PLC) setup, adhering to IEC 61131-3 standards for industrial automation. It calculates modules separately for Digital Inputs (DI), Digital Outputs (DO), Analog Inputs (AI), and Analog Outputs (AO) based on user-defined module capacities.
The formulas used are: DI Modules = ceil(DI / DI Module Capacity), DO Modules = ceil(DO / DO Module Capacity), AI Modules = ceil(AI / AI Module Capacity), and AO Modules = ceil(AO / AO Module Capacity). The bar chart visualizes the I/O and module distribution, aiding in system design and cost optimization.
Use this tool to plan PLC hardware efficiently, ensuring compliance with international standards and precise module allocation. Download the report as a PDF for documentation.
