 |
|
Hi,
I have an issue with reading an optical sensor which have 2-bit gray code output.
I had search in TIA v12 for a library with gray code but i didn't found.
How could i read/convert the sensor gray code output.
Mainly i'm interested to determine the direction and than apply to a counter. |

How do you convert values from Gray Code to BCD code in STEP 7 (TIA Portal)?
Use STEP 7 (TIA Portal) V13 SP1
Call the "Gray_to_BCD" block in your user program if you want to convert a Gray Code into a BCD Code. The block can process an encoding of up to 32 bits maximum. You do not need to interconnect points you do not need.
Call the "BCD_to_Gray" block in your user program if you want to convert a BCD Code into a Gray Code. The block can process an encoding of up to 32 bits maximum. You do not need to interconnect points you do not need.
The download includes the TIA Portal library "Gray-Code.zip".
