Read/Write Multiple Registers Rollout

This rollout is used to configure Read/Write Multiple Registers function parameters. It consists of Read Address, Read Quantity, Write Address, Write Quantity fields and a list. Register is a 16-bit value.


Below are the steps you need to perform to configure the Mask Write Register function parameters properly.

  1. Enter the starting read address in the Read Address edit box. Valid values are from 0 to 65535.
  2. Enter the number of registers in the Read Quantity edit box. Valid values are from 0 to 118.
  3. Enter the starting write address in the Write Address edit box. Valid values are from 0 to 65535.
  4. Enter the register number in the Write Quantity edit box. See the registers added to the list or removed from it. By default, all of them have a zero value.
  5. To change the register value, select it, then enter the value into the Register Value edit box and press the Set button (or press the ENTER key).
  6. Repeat the previous step until all registers are added.

Note: you can use “fast register entering” method. It is used when the number of registers is too big. Repeat these steps:

  1. Select the first register in list.
  2. Enter register value into the Register Value edit box.
  3. Press the ENTER key. The highlighted register's value will be updated and the next register becomes active. Repeat steps 2 and 3 for each remaining register.

The context menu offers you the following functions:

Save to file
Saves all entered register values to comma-separated file (.CSV).
Load from file
Loads register values from comma-separated file (.CSV).
