In this version of the standard firmware you will find the following new features: HTTP auto logout - the ability to activate automatic logout of the session after 5 minutes of inactivity (you will be asked for username/password again). Another innovation is the ability to send the status of all outputs with one command (via bitmask) - the function is available via HTTP, MQTT and SNMP!

The brand new concept NetControl PRO+ is available! 

The PRO+ series of NetControl is distinguished by the large number of input-output circuits (total 32 pcs.: open collector outputs and alarm inputs) and the possibility of adding expanders on both sides of the controller (via side slides on the DIN rail). Thus, power circuits (e.g. 220V) are not used in the main controller, but they are moved to the expanders. All input-output circuits are on detachable screw terminals (in groups of 4). All models support "Passive PoE In" - they can be powered with (11-15)VDC through the free pairs of the UTP cable: 4/5='+', 7/8='-'. On request, it is possible to add a DC/DC converter, with which "Passive PoE In" can support 20-100VDC.

 In this firmware modification, we have added a module for communication according to the IEC 60870-5-104 protocol, which is used by SCADA systems, for example by electricity distribution operators. NetControl appears as a Slave and expects a connection from a SCADA system via TCP.

 For greater versatility, a Modbus Master module is also integrated, through which data can be exchanged using this protocol via TCP or RS-485 (a model with such a port is required). There is a close connection between the two protocols - you can "transfer" Modbus registers to and from the IEC104 SCADA system, which allows solving telemetry and control tasks of photovoltaic inverters.

Through IEC104, you can also access the IO and virtual ports available for the model.
