Diagnostic electronics
6
4 Device functions
The diagnostic electronics has
– 2 analogue inputs
– 4 dynamic inputs
– 1 analogue or digital output
– 1 digital output
– 1 TCP/IP parameter setting interface
– 2 Modbus TCP ports
Input IN1: connection for a pulse signal (HTL).
Input IN2: connection for an analogue current signal (4...20 mA).
The analogue inputs can be used
– as trigger for measurements (e.g. rotational speed for vibration diagnostics)
– as trigger of a counter
– for process monitoring
VSA, VSP or standard IEPE acceleration sensors can be connected to the dynamic inputs.
The dynamic inputs can be used for
– vibration monitoring
– vibration diagnostics
– analysis of other dynamic signals
The hardware outputs can be configured as 2 x binary (NO/NC) or as 1 x analogue (0/4…20 mA) and
1x binary (NO/NC).
The outputs can be used for
– time-critical alarms (e.g. machine protection, response time up to 1 ms)
– alarm output
– analogue value output of values measured by the diagnostic electronics
The parameter setting interface (TCP/IP) is used for communication between the diagnostic
electronics and a PC (e.g. VES004 parameter setting software).
The parameter setting interface can be used for
– parameter setting of the device
– online data monitoring
– reading the history memory
– firmware update
The Modbus TCP ports are used for the communication between the diagnostic electronics and a
Modbus TCP client/master (e.g. PLC).
The Modbus TCP interface can be used for
– transferring the current measured values, limits and alarm states of the diagnostic electronics to
the PLC
– reading the counter readings of the diagnostic electronics
– writing rotational speeds and other values from the PLC to the diagnostic electronics
– writing teach values from the PLC to the diagnostic electronics
