Project Planning and Startup
The SEW parameter data channel can be addressed via Class 7, Instance 1 ... 9 and
Attribute 4 (? Statement of Conformance).
In rung 5, the 9 bytes starting from N7:0 are copied into the M0-file with a rising edge of
bit B3:0/1. This starts the reading of parameter 8304 (2070
hex
). In rung 6, the system
waits for the rising edge of scanner bit I:3.0/15. I:3.0/15 shows that the data are present.
Request profile B3:0/1 can then be reset.
At this point, the received data still have to be written into the N-file. To this end, nine
words of the M1-files N7:10...19 are written.
