Dear Expert, I would like to ask regarding 4 wire wiring recommendation, based on S7 300 module data manual page 372, that COMP+ (Terminal No.10) and Mana (Terminal No.11) are connected to M- (each channel input signal), but based on SM331_AI_8x12_Getting_STarted page 23, only Mana (terminal No.11) that is connected to M-(each channel input signal) and when I compared to the same document on page 25 (graphic/photograph attachment),Mana is not connected to the M-, I am confused the information that I have read on both document,I really need advice and recommendation (best on practice) which on is the correct one? Is there any experience that it doesn't need to connect Mana or COMP+ to M- (each channel input signal), but it can read the signal without any issue? Thank You |
