NOTE
It is possible to use the status data of the THERMO module as input data. Then the user must
chose the module named “
"4THERMO M12 (input+status)".
Then the input data are
formed of the two counters and the status data (as seen in the Chapter diagnostic data).
6.6.9 SAI-AU M12 SB CNT
Input data Description
CNT1 32 bit counter value Channel 0
CNT2 32 bit counter value Channel 1
Output data Description
CNTVAL 32 bit value for writing threshold and counter values
CNTCTRL0 Counter Channel 0 control byte
Bit 0 : counter clearance (must be 1 for the counter to operate)
Bit 1 : Control of the digital output associated with the counter :
0 = output is set manually
1 = output is controlled by the counter value
Bit 2 : state of the digital output when setting manually
0 = clear digital output
1 = set digital output
Bit 3 : Clear fault/status information of the Counter channels
Bit 4 : reserved
Bit 6 to 5 : addressing of register to write CNTVAL to
00 write threshold value for setting output to 1
01 write threshold value for clearing digital output
10 write threshold value for resetting the counter value to zero
11 write actual counter value
Bit 7: write initiate
CNTCTRL1 Counter Channel 1 control byte
Bit 0 : counter clearance (must be 1 for the counter to operate)
Bit 1 : Control of the digital output associated with the counter :
0 = output is set manually
1 = output is controlled by the counter value
Bit 2 : state of the digital output when setting manually
0 = clear digital output
1 = set digital output
Bit 3 : Clear fault/status information of the Counter channels
Bit 4 : reserved
Bit 6 to 5 : addressing of register to write CNTVAL to
00 write threshold value for setting output to 1
01 write threshold value for clearing digital output
10 write threshold value for resetting the counter value to zero
11 write actual counter value
Bit 7: write initiate
