The backplane combines the node adapter and the I/O modules into

a mechanically robust EMC compliant unit. Fully assembled I/O stations

can thus be pre-tested after mounting and transferred to the application

without further modification. Backplanes allow for real-time communication

between modules as well as with the node adapter and provide the power

supply to the logic side of the modules.

The IP40 conform structure and the installation concept of the M100 make

it possible to mount the stations directly on or in the machine, either on a

mounting rail or through direct screw mounting. In addition, the individual

modules are bolted and they remain fixed in place, even if subjected to

vibration or shock loads.

Empty slots on backplanes are useful for optional retrofits, machine

variants or for keeping reserve space in plant construction.

The BPC101 backplane slot cover protects each slot from mechanical

influences, electrostatic discharge and contamination.
