Hy all , im nobie , i search over the net to see what tipe of encoder i need to connect for my siemens s5 . I have an electric schema wich i have to respect .

Nobody knows ?

 Hello Harma,

your encoder is a TTL encoder, you have encoder signal and power supply between pin 12 (Up=5V) and pin 10 (M=0V).

about the connection on plc side I dont know board 6ES521-1AA11.

Are you sure you write the correct code??

Also S5 U110 for me has no meaning..... do you mean S5-100U? or 115U?? or 101U??

can you provide a photo of your s5 boards??

hi , i have :  siemens s5-115u cpu 942 and my encoder is siemens 6fx2001-2CF00 

 and your input board?????

i don`t know what i connect to M in my electric schema ....

i saw over the net nullmarke = zero mark in german (i choice to connect  pin 10 of encoder 0v)

and the pin 12/2 on +5v
