SINUMERIK 840Di Manual (HBI) – 06.03 Edition
In order to synchronize several operator components, the PLC program must be
adapted accordingly. This is the user's (machine manufacturer's) responsibility.
MCPNum: INT:= 1;
MCP1In: POINTER;
MCP1Out: POINTER;
MCP1StatSend: POINTER;
MCP1StatRec: POINTER;
MCP1BusAdr: INT:= 6;
MCP1Timeout: S5TIME:= S5T#700MS; // should be kept
MCP1Cycl: S5TIME:= S5T#200MS; // should be kept
MCPMPI: BOOL:= FALSE;
The MCP2... parameters are only needed if in addition to the 1st MCP, a 2nd
MCP or HT 6 is used:
MCP2In: POINTER;
MCP2Out: POINTER;
MCP2StatSend: POINTER;
MCP2StatRec: POINTER;
MCP2BusAdr: INT;
MCP2Timeout: S5TIME:= S5T#700MS; // should be kept
MCP2Cycl: S5TIME:= S5T#200MS; // should be kept
The parameters listed below serve to synchronize two operator components:
MCP1Stop: BOOL:= FALSE;
MCP2Stop: BOOL:= FALSE;
MCP1NotSend: BOOL:= FALSE;
MCP2NotSend: BOOL:= FALSE;
Notice
A maximum of two MCP/HT 6 can be operated on an MPI line. To be able to
use MCP and HT 6 on an automation system alternately or simultaneously, the
user (machine manufacturer) has to adapt the PLC program accordingly.
For a detailed description of the basic PLC program or of function block FB 1,
please refer to:

Section: FB 1: RUN_UP Basic program, start-up section
FC 19 (for version "M" MCP, milling) or FC 25 (for version "T" MCP, turning)
transfers the signals of the MCP to the NC through the interface.
