InstructionReadBlockSensor InterfaceReadBlock - read a block of data from deviceReadBlock (Write Block) is used to read a block of data from a device connected to theserial sensor interface. The data is stored in a file on ramdisk or floppy disk.The sensor interface communicates with a maximum of two sensors over serial channels using the RTP1 transport protocol. The two channels must be named “laser1:” and “swg:”.This is an example of a sensor channel configuration.COM_PHY_CHANN:-name “sio1:” -type “sio”-Channel 1-Baudrate 19200COM_TRP:-Name “laser1:”-Type “RTP1” -PhyChnnel “sio1”ExampleCONST string SensorPar := “flp1:senpar.cfg”;CONST num ParBlock:= 1;!

SensorNo 0 selects the sensor connected to the “laser1:” channel.SensorNo 1 selects the sensor connected to the “swg:” channel.If the argument is left out the default SensorNo 0 is used.RAPID reference manual - part 1a, Instructions A-R 379
