Step Description
14. Save and compile the hardware configuration data, then download these to the PLC. Adapt the
PG / PC interface.
The hardware configuration and the firmware of the integrated technology are downloaded to
the PLC.
Result: After you compiled the data, the project dialog box in SIMATIC Manager shows the
"technology" folder with its "Technology objects" object.
4.2.2 I/O address areas of the integrated technology
The I/O address area of the integrated technology is organized in two areas.
I/O address area of the I/O image DP(DRIVE)
Address area 0 to 63 is maintained in the integrated technology as I/O image
DP(DRIVE). Any addresses of the integrated technology or of standard slaves on
DP(DRIVE) written to this address area can be read in the user program by means
of the technology function "MC_ReadPeriphery" or written by means of the
"MC_WritePeriphery" technology function. Addresses accessed by technology
objects may not be located in this address area.
I/O address areas accessed by technology objects
Addresses accessed by technology objects must be located in address area 64 to
1023. The "MC_ReadPeriphery" and "MC_WritePeriphery" technology functions
can not be used to access this address area.
