PCO Modbus Tags Address


Hello Experts,

I am trying to connect SAP PCo with a robot from Universal Robots (Model UR5E). This robot uses Modbus protocol.

Using Kepware to test the connection, I am able to create the tags and successfully connect with the robot.

On SAP Pco, according to SAP guide:

I should be able to create Modbus tags using the format:

Input register: 300000 … 365535 (or H30000 … H3FFFF)

Holding register: 400000 … 465535 (or H40000 … H4FFFF)

But Pco triggers an error that I don't know how to fix: The address is outside the configured address space

I am using the same address defined on the cobot, that I already validated on Kepware, but Pco is not accepting it.

If I remove the first number from address: "3" , the size changes from 1 to 16, which should be the correct one.

I tried using the HEX numbers, but same problem.

I don't know how to map the addresses on PCO. I would appreciate your guide.

Thank you so much,
