Bringing decentralized periphery into new dimensions: With the launch of the M100, Bachmann delivers an I/O system which, thanks to its uncompromising robustness, fits perfectly into the Bachmann portfolio. But not only that – the M100’s compact dimensions also open up completely new possibilities for machine and plant builders.

Modular machine concepts in demanding environments significantly reduce the cost of variants. The decentralized positioning of I/O stations also reduces wiring effort, and therefore costs. With the M100 I/O system, up to 744 digital or 372 analog channels per station can be positioned cost-effectively in the smallest possible space.


For the first release, Bachmann has utilized EtherCAT as a standardized, real-time capable fieldbus. The NEC102 IO node adapter maps the powerful and flexibly configurable M100 station to a standard EtherCAT interface. The operating modes of the M100 I/O modules are defined during the configuration and are available to both the M1 master and also to masters of other manufacturers. Thanks to distributed clocks on the EtherCAT stations that can also be synchronized with external time servers, the implementation of short control intervals across the entire control system is given.

Bachmann adopted the most up-to-date approaches when designing the hardware platform: System architectures, processors, logic, and signal interfaces are based on the newest technologies and provide a backbone for minimal power loss, ultra-fast data transmission and next-generation IT security. Secure Boot initialization prevents any compromise to fieldbus hardware, and enables the secure integration of remote I/O stations into the automation network.
