When slave device sends a reply information, it puts its address into the reply information frame\'s address in order to let primary device know which slave device made that response. The range of address code is from 1 to 254.Function Code: When information is delivered from primary device to slave device, the function code would inform slave code what action should be carried out. When slave device replies, it uses function code to judge whether it\'s a normal reply or an objectionable reply. (Function code\'s top position of objectionable reply is 1). MAGA series encoder only support function code03 till now.CodeImplicationOperation03reading datareturn to encoder\'s current valueData Area: The information that primary devices send to slave devices includes some additional information that needs to be carried out by encoder. Without error, the data area sent back from slave devices include the data required by primary devices. If there\'s an error, objectionable code is included in this area.Error-Checking Code: Error-Checking adopts CRC method, mainframe and encoder can use checking code to judge whether there\'s any wrong when accept information. When the data is transmitted, low-order of CRC value ahead, and high-order behind. The generator polynomial that CRC adopts is  g（x）=X16+X12+X 5 +1Technical parametersEnvironmental ParameterOperating Temperature-20～60℃Relative Humidity30~85%RH（No Condensation）Level of ProtectionIP65Electric ParameterSupply Voltage5V，12V，24 or 8～29VMechanical ParameterMaximum permissible Revolution5000r/minImpact ResistanceGB/T 2423.5-1995 100g，6msVibration ResistanceGB/T 2423.10-1995 10g，10~500HzStarting Torque5.0×10-2N·mAxial20NRadial10NRotational Inertia9×10-8kg·m2Permissible Angular Acceleration1×104rad/s
