Optical Micrometers. RF656XY Series

Optical Micrometers. RF656XY Series • Use supply voltage and interfaces indicated in the sensor specifications. • In connection/disconnection of cables, the micrometer power must be switched off. • Do not use micrometers in locations close to powerful light sources. • To obtain stable results, wait about 20 minutes after micrometer activation to achieve uniform micrometer warm-up. 2. CE compliance The micrometers have been developed for use in industry and meet the requirements of the following Directives: EU directive 2014/30/EU. Electromagnetic compatibility (EMC). • EU directive 2011/65/EU,...

Optical Micrometers. RF656XY Series Structure and operating principle The micrometer operation is based on the so-called ‘shadow’ principle, Fig.1. The micrometer consists of two blocks – transmitter and receiver. Radiation of a semiconductor laser or LED 1 is collimated by a lens 2. With an object placed in the collimated beam region, shadow image formed is scanned with a CCD photo-detector array 3. A processor 4 calculates the position (size) of the object from the position of shadow border (borders). Overall and mounting dimensions of the RF656XY micrometers are shown in Figures 2-6.

Optical Micrometers. RF656XY Series This parameter specifies one of the three result sampling options in the case where the micrometer works in the data stream mode: • Asynchronous Transmission • Synchronous transmission, Time sampling; • Synchronous transmission, Trigger sampling. With Asynchronous Transmission selected, the micrometer automatically transmits the measurement result via serial interface as it is ready. With Time Sampling selected, the micrometer automatically transmits the measurement result via serial interface in accordance with selected time interval (sampling period). With...

Optical Micrometers. RF656XY Series 10.4. Number of averaged values/time of averaging This parameter specifies the number of source results to be averaged for deriving the output value. Averaging over a number of results does not affect the data update in the sensor output buffer. Note. Maximum parameters value is 127. The micrometer can operate in the following modes: • Measurement of the position of one border (knife). • The distance between borders A and B (measuring the size of the object or hole). Result = B - A. • The position of the object (its center). Result = (B + A) / 2. • Detection...

Optical Micrometers. RF656XY Series The measurement domain can include up to 64 borders, however, measurement can be made in relation to any two borders (hereinafter - borders A and B), whose numbers are specified by this parameter. Border numbers are counted in the direction of scanning. Direction of scanning is indicated on the body of receiver. 11.1. RS485 port In accordance with the protocol accepted and hardware capability, the RS485 port makes it possible to connect up to 127 sensors to one data collection unit by a common bus circuit. Through these serial interfaces measurement data can...

Optical Micrometers. RF656XY Series Data message has the following format: The even parity bit pads 8-bit data to even parity. 11.4.2. Communication sessions types The communications protocol is formed by communication sessions, which are only initiated by the ‘master’ (PC, controller). There are two kinds of sessions with such structures: 1) “request”, [“message”] — [“answer”], square brackets include optional 2) “request” — “data stream” — [“request”]. “Request” (INC) — is a two-byte message, which fully controls communication session. The ‘request’ message is the only one of all messages in...

Optical Micrometers. RF656XY Series equal to "0" - then non-updated result has been transmitted (see Note 1, p. 10.2). SB=0 when parameters transmit; • two additional bits of cyclic binary batch counter (CNT). Bit values in the batch counter are identical for all sendings of one batch. The value of batch counter is incremented by the sending of each burst and is used for formation (assembly) of batches or bursts as well as for control of batch losses in receiving data streams. The following is the format of two ‘answer’ data bursts for transmission of byte: 11.4.6. Data stream ‘Data stream’ is...

Optical Micrometers. RF656XY Series 12.4. Range of the analog output 16 While working with the analog output, resolution can be increased by using the ‘Window in the operating range’ function which makes it possible to select a window of required size and position in the operating range of the sensor within which the whole range of analog output signal will be scaled. Note. If the beginning of the range of the analog signal is set at a higher value than the end value of the range, this will change the direction of rise of the analog signal. Logical outputs of the micrometer are used to signal...
