SOLAR_NORMALIZE_ANALOG¶
| Available as of PLC runtime system: | V1.3 and above |
| Included in library: | Solar_AC500_V22.lib |
| Type | Function |
| Group | Package of functions to get the sun position |
The SOLAR_NORMALIZE_ANALOG function is used to easily integrate, with any S500 AI/AO card, standard sensor type 4 ““ 20 mA or 0 ““ 10V as positioning sensors for Solar Trackers. This function can be used to integrate analog sensors such as inclinometers.
According to the signal sensor provided and the movement range of the system, SOLAR_NORMALIZE_ANALOG gets the current system position. Internally function SOLAR_NORMALIZE_ANALOG uses the corresponding decimal values given by the AI/AO card when an analog input is detected.
Table below shows the input values (analog signals) with their corresponding decimal values for AX/521 and AX/522 modules.
| Range | 0…10 V | -10…+10 V | 0…20 mA | 4…20 mA | Digital Input | Decimal Value |
