As well as developing a comprehensive network of key industry stakeholders, leading investment community contacts and venture capital institutions and providing our portfolio companies with access to this network to support their fundraising efforts. Metasys N2 is a Serial protocol, while Modbus TCP is an Ethernet based protocol. The SNPX Communications enabler uses the SNPX protocol to communicate with Series 90-30 controllers over a serial line. Isolation prevents interruption of all N2 Bus communication if any of the controllers on the bus become grounded. An MS/TP bus is used for two types of buses: a Field Controller bus (FC) and a Sensor Actuator (SA) Developed By: MS/TP communications buses follow different protocol and wiring rules from N2 communications buses, and MS/TP devices and N2 devices are not compatible on the same bus. An important feature of the N2 Bus is opto-isolation. For information about the specific protocol, please refer to the datasheet for that specific protocol. Controllers running in N2 mode can be used to maintain or modernize sites with installed legacy Johnson Controls® controllers. 2.1 Metasys N2 Communications MC3000 drives running N2 protocol act as N2 devices on a Metasys® Network and function as slaves only.
