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.

The manual includes batch reads/writes, sums and a JSON field-lookup example.

Use a protocol service supported by the model; external-database forwarding stores acquired data.

Check both sides of each tag, arrange addresses and verify the resulting data type.

Verify CPU, RAM and storage for the exact model; system information shows memory use.

Supported models provide time-range queries and exports; retention depends on the model and configuration.

Desktop libraries are stored in MapStorage; browser-editor import is different.

Animation links define display behavior; operation links define input and control.

Open the desktop editor from Configuration; supported devices also provide a browser editor.

Set resolution in page properties and match the background image aspect ratio.

The manual defines Invert as a 0/1 toggle; assign multistate values explicitly.

Use discrete color mappings for individual states and analog mappings for ranges.

The listed IOM models use Modbus RTU; check each address and serial setting before connecting.

Distinguish communication gateways, DDCs with onboard I/O and separate I/O modules.

Enable OPC UA and configure the client with the actual port, authentication and certificate settings.

Run the software project in Local mode on the PC; real I/O and field communication still require hardware validation.

The package documents a PLC ladder editor, graphical programming and DoPI.

They govern a full scan, adjacent requests and a read following a write.

Upload sends a PC project to the device; download retrieves the device project to the PC.

Check each address base and the configured mapping separately.

Both the device and PC need connectivity, and remote upload must first be enabled on the target.

Open the editor from Programmable, create a script and run the syntax check.

Choose a mode that matches the required trigger and avoids unintended repeated commands.

Use the quality code as well as the displayed value.

ReadFromTag reads tag values; MoveValue copies a value between existing tags.

A cyclic group-control script can repeatedly overwrite an individual command.

Create a timing group, select weekdays and times, and check the device clock.
