How to address Modbus TCP data within EcoStruxure Machine Expert Twin?

[DominikSchaefer]

The addressing of Modbus TCP data in Machine Expert Twin is word-wise. Therefore, the data in the holding register must be addressed according to their word address.

Hint: Make sure that the data format (Big / Little endian) matches when transmitting it

Example scenario:

Your application contains a variable (LREAL) with the speed reference for a servo belt in Machine Expert Twin and this is stored in the holding register %ML10.

Example Code in Machine Expert

In order for Machine Expert Twin to access the value correctly, the correct word address must first be determined in the holding register.

%ML10	%MD20	%MW40
		%MW41
	%MD21	%MW42
		%MW43

For the example application it would mean that you have to use the word address %MW40 and enter it as the address in Machine Expert Twin.
