Johnson Controls Metasys NCE25 series - User Manual

NCE25 Installation Instructions
Application
The Metasys
®
Network Control Engine (NCE) 25 Series controllers combine the network supervisor
capabilities and Internet IP network connectivity of a Metasys Network Automation Engine (NAE)
with the I/O point connectivity and direct digital control capabilities of a Metasys Field Equipment
Controller (FEC). These network engines provide a cost-effective solution designed for central plant
applications and large built-up air handlers.
NCE25 Series controllers provide integration to the following network protocols: BACnet/IP, BACnet
MS/TP, and N2 Bus and integrations to other building management communication technologies,
including Modbus
®
, M-Bus, and KNX. The network engine at 9.0.7 is shipped with the licenses and
drivers for all three communication protocols: Modbus, M-Bus, and KNX.
Note: LonWorks
®
is no longer supported for an NCE at Release 9.0.7. All NCEs that feature the
LonWorks integration remain at Release 9.0 or earlier.
Figure 3 shows the physical features of an MS-NCE2567-0 model. See Table 18 for NCE25 Series
model information and features.
Important: For existing custom integrations, contact your local Systems Integration Services
(SIS) team before an upgrade. Updated drivers can be provided on request.
Installation
Follow these guidelines when installing an NCE:
• Transport the NCE in the original container to minimize vibration and shock damage to the
network .
• Verify that all the parts shipped with the NCE.
• Do not drop the NCE or subject it to physical shock.
Parts included
• One NCE with removable terminal plugs.
• One data protection battery installed and connected when the NCE is shipped.
• One installation instructions sheet.
Materials and special tools needed
• Three fasteners appropriate for the mounting surface (M4 screws [#8] screws).
• One 20 cm (8 in.) or longer piece of 35 mm DIN rail, and appropriate hardware for mounting the
DIN rail.
Mounting
Location considerations
Follow these guidelines when mounting a network engine:
• Ensure that the mounting surface can support the NCE and any user-supplied panel or enclosure.
