Topology SINUMERIK 840Di sl
In case of 840Di sl the machine control panel, the handheld unit are connected via Ethernet or PROFIBUS. The
PLC operating system copies the incoming signals straight to the user interface (e.g. input image) at the cycle
control point. As on the SINUMERIK 840 D sl, transfer to the VDI interface is performed by the user program or
by standard blocks of the basic program (e.g. FC19).
Bus addresses
On Ethernet components, MAC and IP addresses or logic names are determining factors in respect of
communication. The control system's system programs convert logic names into MAC or IP addresses. On the
PLC, the numeric component of the logic name is used for communication. This numeric part is specified by the
user to the FB 1 via the parameter "MCPxBusAdr".
The logical name of an MCP or HHU always begins with "DIP". This is followed by a number corresponding to the
switch position of the MCP component (e.g. DIP 192, DIP 17).
MCP interface in the PLC
The signals from the machine control panel are routed by default via the I/O interface to the PLC area. A
distinction must be made between NC and machinespecific signals. NC-specific key signals are distributed to
the relevant mode-group-, NCK-, axis- and spindle-specific interface by FC19 (or FC24, FC25, FC26, depending
on the type of MCP) by default. The reverse applies to the associated status signals, which are routed to the
MCP interface. For this purpose, FC 19 or the other blocks mentioned above must be called in the user program.
Customized keys, which can be used to trigger a wide range of machine functions, must be evaluated directly by
the user program. The user program also routes the status signals to the output area for the LEDs.
