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;
// number of active operator components
// MCP/HT 6 (default = 1; max. = 2)
MCP1In:
POINTER;
// address of MCP 1 input signals
MCP1Out:
POINTER; //
address
of MCP 1 output signals
MCP1StatSend:
POINTER;
// Addr. of the MCP1 send status data
MCP1StatRec:
POINTER; //
Addr.
of
the MCP1 receive status data
MCP1BusAdr:
INT:= 6;
// default MPI address of the MCP
MCP1Timeout:
S5TIME:= S5T#700MS; // should be kept
MCP1Cycl:
S5TIME:= S5T#200MS; // should be kept
MCPMPI:
BOOL:= FALSE;
// MCP/HT 6 is operated at the “extended”
// MPI bus
The MCP2... parameters are only needed if in addition to the 1st MCP, a 2nd
MCP or HT 6 is used:
MCP2In:
POINTER; //
address
of the MCP/HT 6 2 input signals
MCP2Out:
POINTER; //
address
of the MCP/HT 6 2 output signals
MCP2StatSend:
POINTER; //
Addr.
of the send status data MCP/HT 6 2
MCP2StatRec:
POINTER; //
Addr.
of the MCP1 receive status data MCP/
// HT 6 2
MCP2BusAdr:
INT;
// MPI address
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;
// transfer of the relevant operator component:
MCP2Stop:
BOOL:= FALSE;
// FALSE = start; TRUE = stop
MCP1NotSend:
BOOL:= FALSE;
// Send and receive mode of the corresponding
MCP2NotSend:
BOOL:= FALSE;
// Operator component:
// FALSE = send and receive is active
// TRUE = only receive is active
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:

Description of Functions, Basic Machine: P3, Basic PLC Program
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.
