The PD 600 series of devices consists of a versatile mixture of
both standard input/output and special devices, and additional
modules will be regularly added to the family. Coupling this with
the ability to add local programmability and gateways, ensures
that the Multi-master, Multi-net facilities offered by the P‑NET
Fieldbus protocol can be fully utilised.

Due to the fact that each M36 module offers a limited number of
channels, ensures that local clusters can be designed to reduce
unused channels to the absolute minimum. This in turn leads to
minimising the cost and size of each cluster.
