Hi @Wgreeff 

Just to clarify, Modbus Register 2400 is for onboard Digital Inputs Status Validity indicating if related input(S1, S2 or S3) are used or not and if yes to which port it is assigned.

And if you would like to see the status of Digital Inputs(S1, S2 or S3), as mentioned in similar query PM8240 Digital Input, you need to read registers 2401(second 16-bit BITMAP) three lowest-order bits for S1, S2 and S3 of the digital inputs on the base unit (1=ON, 0=OFF).
Note:
Reading modbus address 2401 alone will result in meter returning 0xFFFF for all requests regardless of input state. You will need to read 2400 and 2401 to get the actual input states. Where results are 2400 should be 0000 0000 0000 0111, and 2401 will be 0000 0000 0000 0XYZ, where X is S3, Y is S2, Z is S1.

For more info how to integrate data in EBO platform, kindly post your query in EBO forum.
