For a detailed description of the PLC basic program or of function block FB 1,
please refer to:
/FB1/ Description of Functions, Basic Functions: PLC Basic Program P3
Section: FB 1: RUN_UP Basic program, startup section
The following function blocks are available to transfer the MCP signals to the
VDI interface:
S FC 19: MCP_IFM, version M (milling)
S FC 24: MCP_IFM2, version M (milling)
S 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
and/or assign the interface the appropriate parameters.

The following example shows the communication parameter settings for func-
tion block FB 1 for an MCP:
MCPNum := 1 // Number of MCPs
MCP1In := P#E0.0 // Address: Input data
MCP1Out := P#A0.0 // Address: Output data
MCP1StatRec := P#A8190.0 // Configured diagnostic address
MCP1BusAdr := 192 // MCP address (switch S2)
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
MCPBusTyp := B#16#55 // Ethernet
An MCP failure is detected by the PLC basic program immediately after restart-
ing the PLC, even if no data have been exchanged between the MCP and PLC.
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:
S 1st MCP alarm: ”400260 Failure of machine control panel 1”
S 2nd MCP alarm: ”400261 Failure of machine control panel 2”
