Rockwell Automation 160IB1 InterBus Communication Module - Manual (Page 35)

Using the 160-IB1 on InterBus 6–9
Select the Advanced Config button, to setup the card as shown. This
means that there are 32 words reserved for process data (I/O) and the
M files are set to 384 words. To make PCP function we need to setup
the G files with data . So the G files length = 7.
Select the Edit G file data button, to setup the data for the InterBus
telegram. (see SST-IBS-SLC user manual for details)
Word 0 is fixed by the SLC
Word 1 bit 12=1 (4096)
Word 5 defines where M files stop for I/O and where M files start for
PCP (225)
Word 6 Command buffer size for PCP
These values are just an example of setup and the SST-IBS-SLC user
manual should be consulted to optimise the PCP setup.
Download this I/O configuration to the SLC. The card is now setup to
communicate with the InterBus telegram.
How it works
The number of words to be setup in the M files, varies as the type of
message to be transmitted. In the sample program following, the M
files are being copied to integer files so we can easily send/receive
data.
N7:70 is M0:3.225 onwards – the output data to the drive
N7:80 is M1:3.225 onwards – the input data from the drive
