AFM1200 RS232/485 RTU(DNP3) I/O TERMİNAL PLC

AFM1200 is all in one remote terminal unit (RTU) used in automation/telemetry/IoT (internet of things) applications, combining serial connection and PLC features.


In addition to the standard RTU features such as digital, analogue input and output and serial communication features, it also implements PLC features based on FBD (functional block diagram).


By implementing the DNP3 protocol, precise input and output measurements can be recorded (Class 1,2,3). The total number of event records is 16684. Due to the DNP3 protocol, alarms can be sent when desired without sending a query.


The data retention time of the recorded event log values in the device is >200 years under normal temperature conditions.


Unlike other protocols, the most important advantage of the DNP3 protocol is real-time processing. In this real-time process, the lowest analogue recording interval (sensitivity) is 20ms, and the digital input sensitivity is 1 ms.


In addition to the fact that AFM1200 can perform operations in real time thanks to its implementation of the DNP3 protocol, the real time sensitivity on which these operations are based is designed to be ±1 ppm, which is the highest value that can be seen in industrial devices. In this way, there is no need for time correction in the short and medium term.


Another important feature is real time clock value retention. It has an internal battery so that if the device is not powered in any way, it does not lose time for more than 10 years time with the given ±1 ppm accuracy.


Another important request in automation/telemetry/IoT (internet of things) systems is that the battery does not run out in the long term when using battery power. A sleep feature has been added to the device for such applications. Communication has been enabled by waking up from sleep with different usage scenarios and parameters, and thus usage alternatives have been added to prevent battery drain.


Measurement sensitivity of analogue inputs has 12/14/16 bit options in order to adapt to different demands and conditions.


In some applications, it may be desired to perform some operations according to the values of the inputs and outputs. In these cases, operations based on FBD (functional block diagram) can be performed without the need for an external PLC device by turning on the PLC features of the device and making the necessary adjustments from simple setup interface.
