SINUMERIK 840Di sl Manual (HBIsl) – 01/2007 Edition
This section describes how to link DP slave: MCP 483
S
to the PLC basic program for transferring standard I/O data to the VDI inter-
face
S
to the PLC user program (optional) to implement a user–specific response to
a module failure
Notice
Processing of additional I/O data is the sole responsibility of the user (machine
manufacturer) and is not supported by the PLC basic program.
To transfer standard MCP 483C IE input/output data IE via the PLC basic pro-
gram, the MCP address configured by means of the S2 switch on the module
must be entered in the communication parameters of the FB 1 function block.
Function block FB 1
The communication parameters of the MCP are called MCPx... (x = 1 or 2) in
function block FB 1. A maximum of 2 machine control panels are supported by
the basic PLC program.
To synchronize several MCPs, the PLC program must be adapted accordingly.
This is the user's (machine manufacturer's) responsibility.
To operate an MCP 483C IE on a SINUMERIK 840Di sl, the following parame-
ters are relevant:
MCPNum: INT
MCP1In: POINTER
MCP1Out: POINTER
MCP1BusAdr Byte
The MCP2... parameters are only needed if a 2nd MCP is used in addition to
the 1st MCP:
MCP2In: POINTER
MCP2Out: POINTER
MCP2BusAdr Byte
Bus type via which the MCP is connected:
MCPBusTyp Byte
Notice
Parameters: MCPxStop and MCPxNotSend are of no significance.
