Remote client enables access to Copmact HMI from a standard workstation (no ABB software installed) over plant network. You will require a remote client server (in addition to compact HMI server) and multiple PCs (standard PC with no ABB software installed over plant network) can access real time information. The remote client description is provided in product guide on page 51 & 52. Normally, a project will require normal client (not remote client) only.
