Meter checks all Modbus messages to see if the correct number of registers is requested for the type of data being returned The meter will ignore the request if the number of registers requested does not coincide with the correct number of registers needed to accurately display the data For example Velocity is a floating point value stored in register 40009 40010 Because all floating point values require two registers the meter would ignore a request to read just the data in register 40009 yet it would respond correctly to a request to read the data stored in both registers 40009 AND 40010 Consequently if the meter received a single request to read both Level 40007 40008 and Velocity 40009 40010 the request would have to be for an even number of registers for the meter to respond Problem 980 Flow Meter does not respond to any Modbus message requests _9 Note It is imperative that the DTR be asserted prior to the communication session and that it remains asserted throughout the entire communication session Response Check the DTR Signal Line The 980 Flow Meter will not respond to any Modbus messages until the device connected to the RS232 port asserts raises the DTR line DB 9 Pin 4 on the 1727 cable Response Check the Baud Rate The baud rate of the 980 Flow Meter is configured from 1200 19 200 and must match the baud rate of the device communicating with the meter Response Check the Communication Parameters The
