FAQ

The default IP address is 192.168.1.88. Use Ethernet port 2 on devices with two Ethernet ports. The default web username is admin and the password is admin123456.

Check physical interfaces, protocol support and shared-port arrangements separately, especially native two-wire MBus versus four-wire devices connected through RS485.

Troubleshoot serial and network communication using sent frames, responses and point quality. The source’s 500 ms interval is a tuning example, not a universal default.

I/O requirements select DDC products unless a physical touchscreen is requested; touchscreen models must then satisfy the specified I/O counts as well.

Check acquisition support against the complete model specifications and protocol library. ARM/A9, HMI1002-Lite and HMI1002-Lite-E have different scopes; verify physical interfaces and forwarding separately.

Multiple protocols require an AND match. Manual names are kept exactly, and undocumented compatibility is never treated as confirmed support.

X denotes the acquisition-side protocols. Also check forwarding protocols, communication roles, physical interface types and port counts.

The BACnet website provides information about the building automation communication standard and its ongoing development.

An introduction to BACnet objects, services and networking concepts for building automation.

OPC2Modbus exposes OPC data through Modbus TCP or Modbus RTU. Confirm point requirements against the software version, licence and operating conditions.

Check BACnet object counts, the model’s total acquisition-point capacity and its actual interfaces separately. The source’s 1,024 objects per type is not a universal model capacity.

Check the OPC connection, BACnet object capacity and discovery sequence. The source’s 18,000-object figure applies to its software version, not hardware gateways.

Use OPC2BACnet to expose OPC server data through BACnet/IP for Johnson Controls Metasys to read.
