Access via REST added. All system and service ports can be changed/turned off separately. Introduction of the port list for the overview of open and closed network ports. Reverse function for monitoring the area within the alarm limits added. Function for hiding the menu tree added. Introduction of Web-API and socket-API for separating the access ports for measurement value query. Problem with "Sensor lost" message fixed. No sensor was able to be selected. Data transmission rate and device performance improved. Note! When downgrading to version 1.12 you will then have to perform a reset to factory default settings using the internal jumper. If you are querying this device using socket commands (e.g. GET /Single) or HTTP requests, please note the following changes implemented in firmware V1.12 and higher. Due to the incremental introduction of a modern security concept into the device software, it is in this exceptional case unfortunately not possible to offer 100% compatibility with previous firmware versions. Use of the query commands, without a preceding HTTP header, is now implemented using two separate services: Socket-API: Query commands without preceding HTTP header Web-API: Query commands as HTTP request with preceding HTTP header To make these services configurable independently of each other and capable of being turned off individually, various network ports are necessary. Whereas use of the Web-API remains as before on the configured HTTP port, now for the socket-API the (configurable) port 42280 is preset. Use of both services on the same port as used to be the case is now no longer possible. These two query services are disabled by default in firmware V1.12 and higher. If your application queries the device using HTTP requests, create the function as follows: Enable in the menu under Communication paths >> Web-API >> Allow HTTP requests >> enabled If your application queries the device using a socket command, create the function as follows: Enable in the menu under Communication paths >> Socket-API >> TCP ASCII-Sockets >> enabled Note that you must also change the TCP port used to the port configured here (Default: 42280) in your application. If this is not possible, you can also change the HTTP port in the device network settings so that port 80 can be used for the socket API.
