• Tear apart and throw away plastic packaging bags so that children may not play with them and risk suffocation and death. Do not install the MultiSITE VM3 unit if it will be exposed to rain or other precipitation. Do not install the unit in a location exposed to open flame or extreme heat.
Driver configuration and GUI Refer to the MultiSITE VM3 User Manual for details on configuring the LG Niagara 4 driver to monitor and control LG HVAC equipment. The User Manual also describes the features of the controller’s GUI (graphical user interface).
To do this you use the platform Commissioning Wizard. • The Commissioning Wizard is the only way to install the needed core software in a MultiSITE VM3 controller. Most steps in the Commis- sioning Wizard are also available as separate platform views. For example, there is a Software Manager, License Manager, and many others.
Secure storage and the SD card On a MultiSITE VM3, the SD card is the primary storage media for all data and configuration related to the software installation. Since the SD card can be easily removed and the data duplicated, the sensitive data is encrypted when stored on the card. Files are stored in encrypted format, but decoded on the fly as they are accessed.
Refer to the MultiSITE VM3 Installation Guide for mounting, wiring, and installation instructions. This document assumes that you have the MultiSITE VM3 nearby, and are able to power it on and off as needed. After you complete the commissioning process described in this document, you can mount and wire the MultiSITE VM3 controller at the job site.
Commissioning Wizard. NOTE: If you received a license archive (.lar file) or .license file for the MultiSITE VM3 through email, and you wish to use it instead of the online license server (for some reason, for example your MultiSITE Supervisor PC will not have Internet connectivity when you are commis- sioning the MultiSITE VM3), make the file available to MultiSITE Supervisor first, as follows: •...
Connecting to MultiSITE VM3 Once the MultiSITE VM3 has powered up, connect to it with MultiSITE Supervisor using “Open Platform.” A platform connection to any Multi- SITE VM3 is required for most host-level operations. This includes installing Niagara 4.1 core software and modules and performing various other platform tasks.
RUNNING THE COMMISSIONING WIZARD As shown below, the Commissioning Wizard is a right-click option on any connected MultiSITE VM3 platform in the Nav tree. You can also launch the wizard from the Platform Administration view. Figure 4: Commissioning Wizard as right-click platform option.
• Install/upgrade core software from distribution files: Preselected and read-only for any new unit. • Sync with my local system date and time: Preselected in most cases. For a new MultiSITE VM3 for example, the controller time may greatly differ from actual time.
RUNNING THE COMMISSIONING WIZARD Installing or updating licenses At the License step, you install one or more license files in a new MultiSITE VM3 controller. You typically select the option to get and install licenses from the licensing server. Prerequisites A minimum of one license file is always needed.
If a license is not listed, navigate to its location using the left-pane folder tree controls, and click the license to select it. • The licensing tool prevents selection of a wrong license (different hostid) to install in the MultiSITE VM3.
1. Click all module profile types to be installed in this MultiSITE VM3 controller, which include one or more of these: • RUNTIME: Always selected. Note if UX (or UX and WB) is not selected, the MultiSITE VM3 will not support client Web browser access from its WebService—only client access from MultiSITE Supervisor via Fox.
Specifying a station database to install If you have a specific station database ready to install in the MultiSITE VM3, you can specify it at this step in the wizard. Or, accept the de- fault “(Don’t transfer a station)” and click Next. You can create a station later using the New Station Wizard, and install it using the platform’s Station Copier.
4. Click the Next button for the next step. If skipping that step, go to “Select modules”. Installing lexicons At the Lexicon Installation step, you can install one or more text-based lexicon file sets in the MultiSITE VM3, provided you have the file sets in a !lexicons folder under your Sys Home (niagara_home).
Selecting modules At the select modules step, a popup “Rebuilding software list” dialog briefly appears as the dependencies of the MultiSITE VM3 are com- pared against the available software modules in your MultiSITE Supervisor PC’s “software database.” During commissioning, you add to the software modules that are preselected for installation.
Installing or upgrading core software At the install/upgrade core software step, the dependencies of the MultiSITE VM3 platform are compared against the distribution (dist) files available in your MultiSITE Supervisor PC’s “software database.” For the initial commissioning, the wizard determines what core distribution files are needed, selects the files automatically, and then informs you in a dialog, as shown in the following figure.
1. Review the Interface 1 settings on the IPv4 Settings tab, which include the temporary factory-shipped IP address. 2. Assign the MultiSITE VM3 a unique IPv4 address for the network you are installing it on. No other device on this network should use this same IP address.
10 characters and include at least one uppercase character, at least one lowercase character, and at least one digit). The system passphrase is used to protect sensitive information stored on all Niagara systems, and on the micro SD card in MultiSITE VM3 controllers.
MultiSITE VM3 controller. Note that the Commissioning Wizard in Niagara 4 prevents commissioning a MultiSITE VM3 controller that retains the factory default platform user account. To proceed, you must enter a different user name, along with a “strong” password (this means a minimum of 10 characters including: at least one uppercase character, at least one lowercase character, and at least one digit).
RUNNING THE COMMISSIONING WIZARD Specifying a platform user to replace the factory-default platform user You see this dialog only in the initial commissioning of a new MultiSITE VM3 controller, or possibly at some future point after installing an N4 “clean dist” file.
RUNNING THE COMMISSIONING WIZARD Configuring additional platform daemon users This Commissioning Wizard step lets you add additional platform admin users in the MultiSITE VM3 controller, delete users, and change passwords. • Note that you can access this same configuration via the “User Accounts” button in the Platform Administration view, available any time after commissioning.
If you did not change it’s IP address, after several minutes you should be able to double-click the platform instance again to reconnect. Note: Going forward, you must access the MultiSITE VM3 by its new (assigned) IP address. Note that your MultiSITE Supervisor keeps a history of TCP/IP changes made.
If you changed your PC’s IP address in order to commission the MultiSITE VM3, you usually need to reconfigure your PC’s TCP/IP settings back to appropriate settings to communicate with it. Otherwise, you will be unable to connect to it for other commissioning.
ADMINISTRATION A few platform configuration items in a MultiSITE VM3 are not directly accessible in a MultiSITE Supervisor platform connection to the controller, that is, via the Commissioning Wizard or any of the platform views. Instead, you must have a station installed and running on the controller (any station).
PlatformServices is different from all other components in a station in the following ways: • It acts as the station interface to specifics about the host platform (whether MultiSITE VM3 or a PC). • It is built dynamically at station runtime. PlatformServices is not visible in an offline station.
Some properties are read-only status types, similar to many seen in the Platform Administration view. Other configuration properties can be edited. A group of 3 config properties allow adjustment of the time, date, and time zone settings for the host MultiSITE VM3 (alternatively accessible using a platform connection to the MultiSITE VM3).
3. By default, the Service Enabled property is true. This is appropriate since the controller has no backup battery installed. If a “battery-less” MultiSITE VM3 controller is powered from a battery-backed UPS, you could also choose to set Service Enabled to false.
Optional platform administration The Commissioning Wizard performs most, but sometimes not all, needed configuration for a new MultiSITE VM3 platform. There are several items you should review (and optionally change) in a follow-up platform connection to each MultiSITE VM3, using the Platform Administration view.
Note that in Niagara 4, “SSL” is always implemented using the TLS (Transport Layer Security) protocol. • Enable or disable SFTP (Secure File Transfer Protocol) and SSH (Secure Shell) access to the MultiSITE VM3 controller. By default, such access is disabled, where both protocols use TCP port 22.
• Change TLS Settings: A dialog to specify platform SSL settings, including enabling/disabling, port, PKI certificate to authenticate by, and secure protocol to use. • Change Date / Time: A dialog to change the MultiSITE VM3’s current date, time, and time zone. This is initially performed as a step in commissioning wizard.
REFERENCE INFORMATION During MultiSITE VM3 commissioning, it is possible to run into problems. For instance, you may type an IP address incorrectly when entering it, and as a result be unable to regain access. In this scenario, there are a couple of things you should know about: IP changes history Your MultiSITE Supervisor PC records “before and after”...
In this scenario, your only recovery option is to restore the factory defaults. • When decommissioning a MultiSITE VM3, a best practice to follow is recovering the factory defaults in order to wipe all of the platform and station data in the controller.
• Depending on your preference, you may wish to use the serial shell to set a MultiSITE VM3’s IP address, as an alternative to recon- figuring your PC’s IP address in Windows (to initially connect to a new MultiSITE VM3). If done as the first step, afterwards, you could connect normally (Ethernet/IP) and perform all other Niagara software installation/platform configuration using MultiSITE Supervisor and the Commissioning Wizard.
6. In the tree in the PuTTY Configuration dialog, click Session and then click/select the “Connection type” as Serial. • (Optional) You can save this configuration to reuse (load) in future PuTTY to MultiSITE VM3 serial sessions. To do this, type in a connec- tion name in the “Saved Sessions”...
If you change platform login credentials and then lose or forget them, you can restore the “factory default” platform login credentials. However, you will need to make a debug system shell connection, reboot the MultiSITE VM3, and then be careful to press a key at the ap- propriate time during MultiSITE VM3 boot up.
Note: After you save the network settings, they do not become active until you perform a reboot of the MultiSITE VM3 controller. You can do this when you return to the main system shell menu, by selecting Reboot, menu option 6.
