1, -10 - 10V. When the voltage is -10V - 10V, it is converted to F448-0BB8Hex (-3000-3000) at 6000 resolution; it is converted to E890-1770Hex (-6000-6000) at 12000 resolution.
2, 0-10V. When the voltage of 0-10V is converted to 0-1770Hex (0-6000) at 12000 resolution, it is converted to 0-2EE0Hex (0-12000) at 12000 resolution.
3, 0-20mA. When the current is 0-20mA, it is converted to 0-1770Hex (0-6000) at 6000 resolution; 0-2EE0Hex (0-12000) is converted to 12000 resolution.
4, 4-20mA. When the current is 4-20mA, it is converted to 0-1770Hex (0-6000) at 6000 resolution; 0-2EE0Hex (0-12000) is converted to 12000 resolution.
The above is only a brief introduction. Different plcs have different resolutions, and the range of physical quantities you measure is different. The calculation results may have some differences.
Note: Requirements for wiring for analog input
1. Use shielded twisted pair cable, but do not connect shield layer.
2. When an input is not in use, short the V IN and COM terminals.
3. The analog signal line is isolated from the power line (AC power line, high voltage line, etc.).
4. When there is interference on the power line, install a filter between the input part and the power unit.
5. After confirming the correct wiring, first power on the CPU unit, and then power on the load.
6. Turn off the power of the load before powering off, and then cut off the power of the CPU.
