Failsafe Networks: Most requests for failsafe Profibus network configurations are concerned about using two CPU’s and one network cable with I/O that can "failsafe" in the event of a catastrophic network communication loss. All Acromag 98xPB and 97xPB Discrete and Analog Output Modules have outputs that may be configured to fail in the last state or predefined state in the event of network communications which support "failsafe" systems.

Redundant Networks: Systems requiring complete redundancy typically intend to double their cpu, network communications cable, and I/O counts. Since Acromag’s 9xxPB I/O modules are very economical and compact, it is now feasible from a budget and space perspective to use twice the amount of I/O for fully redundant system requirements. Remember, Acromag’s 9xxPB I/O modules don’t require the cost or space of buscouplers, racks, or special power supplies.
