3. Type the starting register value in the Data Addr field.

Note

The data type is set automatically by the Modbus program, based on the specified data address.

4.In the Quantity field, type the number of registers to be retrieved. The Modbus program will accept a quantity value of 1 to 2016. The requested number of registers cannot exceed the amount contained by the selected message block but you can retrieve a partial block. You cannot cross a message block boundary.

Also, in Standard Modbus mode each register is 16 bits. Therefore, integers (SHORT) consist of 1 register while floats (FLOAT) and long integers (LONG) consist of 2 registers.

Note

Boolean registers are not user-defined (for either SIM_2251 or User_Modbus) and primarily contain alarm flags useful for debugging. To view the contents of Boolean registers, select the 1 (Read Coil) function code.

Numeric registers for User_Modbus can be user-defined. To view the contents of Numeric registers, select the 3 (Read Regs) function code.
