VDI interface parameter assignment
The following function blocks are available to transfer the MCP signals to the VDI interface:
●
FC 19: MCP_IFM, version M (milling)
●
FC 24: MCP_IFM2, version M (milling)
●
FC 25: MCP_IFT, 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:
/FB1/ Function Manual - Basic Functions; P3 Basic PLC 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
:= 1
// Number of MCP
MCP1In
:= P#E0.0
// Address: Input data
MCP1Out
:= P#A0.0
// Address: Output data
MCP1BusAdr
:= 192
// MCP address (switch S2)
MCP1Timeout
:= S5T#700MS
// Default setting
MCPMPI
:= FALSE
// No MPI bus
MCP1Stop
:= FALSE
// Deactivation of the DP slave MCP
MCP1NotSend
:= FALSE
// Send and receive operation activated
MCPSDB210
:= FALSE
// No SDB210 for MCP
MCPCopyDB77
:= FALSE
// No copying to DB77
MCPBusType
:= B#16#55
// Ethernet
MCP failure
The basic PLC program detects an MCL failure even if no data is exchanged between MCP
and PLC. For instance, after a PLC restart.
The monitoring function is activated as soon as all components have signaled "Ready" after
powerup.
An alarm is displayed on the user interface if an MCP fails:
●
1. MCP alarm: "400260 Failure of machine control panel 1"
●
2. MCP alarm: "400261 Failure of machine control panel 2"
