When establishing a four-wire instrument branch cable, with one power line and one signal line, it is important to pay attention to the sequence numbers in the properties field of the two terminal strips, such as TS-1 and TS-2, when creating the device panel in REF. For example, you should modify the sequence numbers to 1 and 2. If you do not make these changes, only one cable will be generated in the cable folder of the domain explorer when the instrument panel and cable are created!
