Good vid, but what if there were three lights instead of two, for example like a motor with forward and reverse, how would you make it that when the forward is on the reverse is off vice versa? Thank you!
In Siemens PLCs, memory addressing typically follows a big endian format. So, when storing a 16-bit binary number like 1100 1111 0000 0101 in PLC memory, it would be arranged as 1100 1111 0000 0101 (Big Endian). However, Human Machine Interfaces (HMIs) often use little endian byte ordering. Therefore, when the same data is stored in HMI memory, it would be arranged as 0000 0101 1100 1111 (Little Endian). Due to this difference in memory arrangement, when referring to specific bits, adjustments may be needed. For instance, bit numbering may need to start from bit 8 instead of bit 0 to account for the different byte ordering between the PLC and the HMI.
Ez mindaddig igaz is, amíg nem jön pl. egy inkrementális enkóder NPN bekötéssel és máris a PLC bemenet sinking-ből sourcing-ra nem vált. Így ez csak egy lehetséges megoldás, valamilyen bemeneti kondícióval...
