Using Custom Modbus Adresses

From Mikrodev Documentation
Jump to navigation Jump to search

When you add new blocks On Mikrodiagram, it automatically assigns some MODBUS register addresses to the block according to its output type.

If needed, you can customise these assigned addresses using the "Variable Address Table" located at "Projects" tab.


Add a register to the project.


On Variable Address Table add an entry for that block. Select the associated Line Label. In the "Start Address Field" write the desired MODBUS address to be used for that register.


Now you have an entry for the block with a new MODBUS address.


The auto-assigned MODBUS address is still valid for that block. But for remote connections to the device, the added entry's start address will be matched to the auto-assigned MODBUS address of the block.
