RE: Siemens S7 M0.0
M 0.0 is the least significant bit of the byte MB0
RE: Siemens S7 M0.0
In the program I am using, M0.0 is read only not written
RE: Siemens S7 M0.0
Each bit from M0.0 through to M0.7 will switch at a different frequency.
Bit of the Clock
Memory Byte 7 6 5 4 3 2 1 0
Period Duration (s) 2.0 1.6 1.0 0.8 0.5 0.4 0.2 0.1
Frequency (Hz) 0.5 0.625 1 1.25 2 2.5 5 10

Bit of the Clock
Memory Byte Period Duration (s) Frequency (Hz)
7 2.0 0.5
6 1.6 0.625
5 1.0 1
4 0.8 1.25
3 0.5 2
2 0.4 2.5
1 0.2 5
0 0.1 10
Hope that shows a bit better, so M0.0 would be a 10Hz clock bit (100mS cycle).
It only does this if enables in the CPU properties and the byte used can be changed from the default byte 0.
