HelloSLA@, The 6ES7431-0HH00-0AB0 has a low common mode voltage. So you will have to connect all -M to ground.
On the other hand the6ES7431-7QH00-0AB0 has a high common mode voltage. So you can ignore the M connection to ground as long as you don't exceed the premissible potential difference between channels and between channels and MANA. Best regards, H-H |
