VDI interface parameter assignment
The following function modules are available for assigning the VDI interface parameters:
● FC 24: Machine control panel MCP 310, version M (milling)
References:
A detailed description of the function blocks for transferring machine control panel signals to
the VDI interface can be found in:
/FB1/ Function Manual - Basic Functions: P3 PLC Basic Program, Section "FC 19:
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
MCP1In
MCP1Out
MCP1StatRec
MCP1BusAdr
MCP1Timeout
MCPMPI
MCP1Stop
MCPSDB210
MCPCopyDB77
MCPBusType
PLC user program
If an MCP is connected via PROFIBUS DP, the basic PLC program does not check for
module failure.
In this case the MCP is monitored by a standard mechanism to monitor the active DP slave:
● PLC operating system
● PROFIBUS controller
On detecting a failure of an MCP 310 DP slave, the PLC is switched to the STOP state by
default.

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.
