Squid

• Communication class availability
  Missing devices
  
• The Amplex Communication Framework (AmpCom) enables two-way multi-carrier communication. AmpCom uses communication classes to define the priority of the data. One or more carriers are assigned to each class. If one carrier is not available, another carrier is used instead. Supported carriers: GSM, WiFi, Ethernet (LoRa in process)
  
• All modules and meters connected to the Squid are automatically discovered by the system. In case a module/meter is disconnected to the Squid, this is reported to the server application and the module/meter is listed as missing. If the module/meter is reconnected to the Squid or another AmsCPU/Squid, it will be rediscovered by the system.
• The Squid has a calendar and a real-time clock with an absolute maximum deviation of ±10 seconds per 24 hours in the full temperature range. This is without synchronization with external units. Under normal conditions, clock deviation is automatically adjusted according to the Network Time Protocol (NTP) which gives a maximum deviation of ± 1 second.
• The collected data are stored in non-volatile memory which holds the values until they are sent to the server. The Squid has the capacity to store data for at least 300,000 historical measurements, depending on the data size of the values.
• A software management system designed to maintain the software on Squids remotely. Enables installation, removal, and upgrade of software through a web user interface on one or more selected Squids. It also allows on-site upgrades with an authenticated USB memory stick or Micro SD card.
• Sub system software, e.g. StartGrid™ logic etc. can be downloaded from the Data Centre application for installation and upgrade.
• From the server application, Squid configuration data can be changed, as required. The configuration data include:
  Communication classes
  Surveillance of communication classes
  MeterMind™ features (an advanced metering infrastructure (AMI) system)
  GreenWise™ features (an advanced power, heat, gas, water benchmarking energy management system)
  StartGrid™ features (a low-voltage power network monitoring and control system)
• #1: (Green LED) – System status (Booting, ready)
  #2: (Yellow LED) – WiFi status (Scanning, associated, disabled)
  #3: (Red LED) – USB hotplug status (Used for showing status when running a script from a USB dongle)
  #4: (Green LED) – Communication status (Connected/disconnected from the server)
