Link all your devices to your software – SensDesk concentrates values from multiple devices

HW group produces various devices with different characteristics and intended applications. Most devices are designed to be integrated into larger monitoring systems using SNMP, XML, Modbus/TCP or MQTT.

However, in order to combine different devices in a single system, either the system needs to support all of them, or a common “concentrator” is needed. The SensDesk portal can play this role.

Support

The devices themselves support numerous protocols; one could therefore avoid a common concentrator and modify the communication protocols directly in the devices. However, this is not realistic due to their different characteristics, communication interfaces, age, and the need to maintain backward compatibility.

For instance, Narrowband devices (NB-devices family) do not offer any standardized outputs and only communicate using a proprietary protocol. Devices connected over GSM/LTE cannot be accessed for reading. And even Ethernet devices have very different properties. The solution is to use the portal. In addition to other functions, the portal provides current values from all devices in a unified way using XML or SNMP.

In case of SNMP, both SNMPv1 and SNMPv3 can be used. Support for SNMP traps (for alarms) is coming soon. Each user is assigned a community and a username for SNMPv3. This is to ensure that each user can only access values which they are authorized to access.

For SNMP, the principle is the same, except that the portal login username and password are used to determine user permissions.
