VDI interface parameter assignment
The following function modules are available for assigning the VDI interface parameters:
●
FC 19: Machine control panel MCP 483, version M (milling)
●
FC 25: Machine control panel MCP 483, version T (turning)
NOTICE
Function blocks FC 19, FC 24 and FC 25 are part of the PLC basic program. It is the
user's (machine manufacturer's) responsibility to call the block correctly or assign the
interface the appropriate parameters.

A detailed description of the function blocks for transferring machine control panel signals to
the VDI interface can be found in:

MCP_IFM ...", Section "FC 24: MCP_IFM2 ...", Section "FC 25: MCP_IFT ..."
Example
The following example shows the communication parameter settings for function block FB 1
for an MCP:
MCPNum
:= 1
// Number of MCP
MCP1In
:= P#E0.0
// Address: Input data
MCP1Out
:= P#A0.0
// Address: Output data
MCP1StatRec
:= P#A8190.0
// Configured diagnostic address
MCP1BusAdr
:= 5
// PROFIBUS address of the MCP DP
slave
MCP1Timeout
:= S5T#700MS
// Default setting
MCPMPI
:= FALSE
// No MPI bus
MCP1Stop
:= FALSE
// Deactivation of the DP slave MCP
MCPSDB210
:= FALSE
// No SDB210 for MCP
MCPCopyDB77
:= FALSE
// No copying to DB77
MCPBusType
:= B#16#33
// PROFIBUS
