Specifying settings without machine control panel
If a PCU or a TCU has no machine control panel (MCP), you must set one of the two following
options:
● MCP address = 0 or no entry
After the change of user authorization, there is no switchover of the machine control panel;
the previously active MCP remains active.
● MCP address = 255
If the user authorization is transferred to this PCU or TCU, the previous machine control
panel is deactivated and there is no active machine control panel from this point on.
