Common FAQ
What is the role of the MAU in a Remote I/O configuration?The1C31179G01acts as the "brain" for a Remote I/O node. It gathers data from the local I/O modules on that remote branch and packages it for transmission over the fiber-optic or copper Ethernet backbone to the main DCS controller.
Is this module hot-swappable?Yes. The1C31179G01is designed to be "hot-swappable," meaning it can be removed and replaced without turning off system power. In a redundant configuration, the partner module will maintain the network link while the swap is performed.
