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 2-7.

Optical Micrometers. RF656XY Series Connection Micrometers without Ethernet interface Micrometers are equipped with Binder 702-8 connector. The connector location and pin numbers are shown in Figure 8. Designation of contacts is given in the following table: Model of Micrometer Assignment IN Gnd (power supply) DATA+ DATAGnd (common for signals) AL (LOUT_max) U/I (LOUT_min) U+ (power supply)

Optical Micrometers. RF656XY Series Micrometers with Ethernet interface Micrometers contain an additional Binder 712-4 connector. The connector location and pin numbers are shown in Figure 9. Designation of contacts is given in the table below: Model of Micrometer ЕТ Configuration parameters The nature of operation of the micrometer depends on its configuration parameters (operation modes), which can be changed only by transmission of commands through serial port RS485. The basic parameters are as follows: This parameter specifies one of the three result sampling options in the case where the...

Optical Micrometers. RF656XY Series Note 1. It should be noted that the ‘sampling mode’ and ‘sampling period’ parameters control only the transmission of data. The micrometer operation algorithm is so built that measurements are taken at a maximum possible rate determined by the integration time period, the measurement results is sent to buffer and stored therein until a new result arrives. The above-mentioned parameters determine the method of the readout of the result form the buffer. Note 2. If the bit-serial interface is used to receive the result, the time required for data transmission...

Optical Micrometers. RF656XY Series The border means “light-shadow’ transition or “shadow-light” transition which forms a shadow image of the object (see Figure 10). Measurement is only conducted in the case where the number of borders detected by micrometer corresponds to a given parameter. The polarity is the “light-shadow’ transition or “shadow-light” transition. Borders can be set with the same polarity and with the different polarity. Numbers of borders under control The measurement domain can include up to 64 borders, however, measurement can be made in relation to any two borders (hereinafter...

Optical Micrometers. RF656XY Series This parameter defines the network address of the sensor equipped with RS485 interface. Note. Network data communications protocol assumes the presence of ‘master’ in the net, which can be a computer or other information-gathering device, and from 1 to 127 ‘slaves’ (RF65x Series sensors) which support the protocol. Each ‘slave’ is assigned a unique network identification code – a device address. The address is used to form requests or inquiries all over the net. Each slave receive inquiries containing its unique address as well as ‘0’ address which is broadcast-oriented...

Optical Micrometers. RF656XY Series first, and then follows higher tetrad. When multi-byte values are transferred, the transmission begins with lower byte. The following is the format of two ‘message’ data bursts for transmission of byte: DAT(7:0) Byte 0 1 "Answer’’ is data burst that can be transmitted by ‘slave’ in the course of the session. All messages with a message burst contain 1 in the most significant digit. Data in a message are transferred in tetrads. When byte is transmitted, lower tetrad goes first, and then follows higher tetrad. When multi-byte values are transferred, the transmission...
