Ensure the power supply via power jumper contacts and data contacts
Emergency operation can only be ensured if the power supply is applied via the power
jumper contacts and data contacts. If one of the two power supplies is interrupted, the I/O
module cannot switch to emergency operation.
To ensure a permanent power supply, the 750-613 I/O module can be used as the supply
module, for example.
