Wiring Safety I/O

Hey All,

i have a stupid question and need some help wiring the safety I/O (6ES7526-1Bh00-AB0). Attached is what i think how E-stops and safety doors should be wired. Also for the safety doors can i wire only the safety outputs (1)?? 

 Thanks for all the help,

Sam 

Hi,

there are helpful application examples available, which shows the wiring.

 Hey Morten,

Thank you for the help. i am a little confused when it comes to using Us0, Us1, Us2 and Us3. it looks like Us0 can only be used with one input. (is that correct)?  

So my question here is, if i use Us0 and DI0 how do i make use of DI1,DI2, and DI3 in that group??  

thanks for the help.

If you flip open the cover of DI module it becomes a lot clearer. You can use U_S0 (terminal 1) with DI₀ to DI₃ on the left (terminals 2 to 8)  and U_S2 (terminal 21) with DI₀ to DI₃ on the right (terminals 22 to 28). Think of it as four blocks of inputs (two left, two right) with their own supplies. You always stay within your block.

okay so one last question, this is (see attached) correct ?? 

If you have four 1-channel sensors that wiring is correct.

However, you have a 2-channel emergency stop and two 2-channel protective doors, right? The two sides of your module (a/b) create your pairs. Wire your emergency stop to CH0 and CH8, protective door 1 to CH1 and CH9, protective door 2 to CH2 and CH10. You can see these pairs also in the configuration of your F-DI (see attachment).

Because of the two different sensor supplies of each channel, the F-DI is able to detect short-circuits between the two channels.

I second Morten's suggested application examples. They are really helpful if you're just getting started with SIMATIC Safety.

Also, there is another application example for protective doors without interlocking:
