Hi, Would like to seek for clarification here regarding this XI110208 module. The purpose of the Up's port is to supply 24VDC out to the peripherals?

Please have a look to the official documentation of the module.
As the module does use 2-wire technique the UP provides a supply voltage for e.g. external switches that is measured at the corresponding DI IN connection. I will check if we can make it clearer in the documentation.
Power supply for sensors or actors probably needs to be attached separately to the external devices, see maximum output current.

So you're saying that the Up port here is use to supply 24V DC to the corresponding peripherals that gives signal to the "DI" port? Will it work if my Up is used to just supply 24VDC to the other peripherals ?
lets say for this module, is it possible that i can use 1 wire-technique( just the DI port) , without connecting anything the "Up" port.

When you connect the ground of an external 24V power supply to the ground of the bus coupler/power module the IO is connected to, you can:
