12. Using ModbusTest mi WATLOW Introduction ModbusTest is an invaluable software testing tool that you may use to validate communications between your PC and a Watlow EZ ZONE family controller In the basic form you will use this tool to either read or write to Modbus registers with in a controller equipped with the Modbus RTU protocol Each Modbus register in the controller contains 16 bits of information called one word All 16 bit words are stored in unsigned integer format Any information that pertains to precision data is stored in two consecutive Modbus registers such as 360 and 361 which together form a location to store a closed loop set point Since each register is 16 bits wide two registers will form 32 bits of information using two words Some information is encoded in 32 bit IEEE 754 floating point format In this way the controller can display process or temperatures to a precision of 0 001 units or degrees Ever piece of information in the controller is referenced by a Modbus register or address location starting at an even number You will never write to an odd numbered Modbus address using relative addressing see more detail below Protocol Background Information Gould Modicon now called AEG Schneider created the protocol referred to as Modbus and used it in process control systems Modbus provides the advantage of being extremely reliable in exchanging information a highly desirable feature for industrial data co
