For a full list of URLs, IPs, and ports required for SAM4 communication, please refer to this table.
The NOVAQ hardware collects current and voltage data via it's sensors installed in the motor control cabinet. These analog inputs are sent to the DAQs, which transforms them into a digital output. This digital output is then processed and analyzed and then sent to Samotics’ cloud environment.
Note that the NOVAQ's Ethernet interfaces are essentially switch ports and not interface ports of the device.
This means that each NOVAQ device can communicate with all devices connected to the same subnet.
It is possible to set a static IP for each NOVAQ device.
Network Requirements
The SAM4 solution requires a bandwidth of 1 Mbit/s per motor. The upload speed should exceed 0.1 Mbit/s per motor with a minimum of 0.5 Mbit/s per NOVAQ. The download speed should be at least 1 Mbit/s per NOVAQ. SAM4 will use approximately 4GB of data per motor on a monthly basis, depending on the running time of the motor. The main source of data is a 15-second condition measurement taken when the motor is active. This is the standard configuration for SAM4, but these settings can be adjusted based on the asset’s context. Additionally, metrics for insights and device management are included (e.g., application updates, security fixes).
Whitelisting
SAM4 requires access to a number of URLs, IPs, protocols and ports for its cloud communication, which will need to be added to the allow listed on any existing firewalls. This table. shows the required allow lists per topic.
Advanced Setup
All cloud communication, including software updates, is initiated by the gateway. Samotics will never initiate an inbound connection to your network. SAM4’s cloud communication is secured via TLS 1.2 and HTTPS protocols. Remote administration of the gateways is secured via SSH and it is the gateway itself that initiates the connection using default secure outgoing ports (443 (HTTPS), 53(DNS), 123(NTP), so your IT department doesn’t have to worry about special rules for the firewall.
You will be able to access Samotics' network tool by connecting a laptop to the sensor network via ethernet cable. From the SAM4 Setup tool main menu, you will be able to see all of the sensors currently connected to the gateway, as well as any networking issues occurring at that time. For every network interface, the tool allows you to perform some basic actions: you will be able to optimise the 4G connection through a live feed of signal strength in the Mobile menu, while the Ethernet and Wi-Fi menus will allow you to set static IPs as well as find nearby Wi-Fi signals.
The SAM4 setup tool comes with an advanced mode allowing for additional setup, such as APN, DNS, NTP and sensor network. In addition, it will also allow you to upgrade all software installed on your gateway as well as its BIOS.
