2.7.11 Configuring machine control panel, handheld unit
General
Up to two machine control panels and one handheld unit can be in operation at the same
time. There are various connection options (Ethernet, PROFIBUS, MPI) for the machine
control panel (MCP) and handheld unit (HHU). It is possible to connect two MCPs to different
bus systems (mixed operation is only possible on Ethernet and PROFIBUS). This can be
achieved using FB1 parameter MCPBusType. In this parameter, the right-hand decade is
responsible for the first MCP and the left-hand decade for the second MCP.
