Example 3:

Sync cycle time (

C01121

)

= 2000 μs

Sync phase position (

C01122

)

= 400 μs

Sync application cycle (

C01130

)

= 2000 μs

PDO delay

= (

C01121

-

C01122

+ 150 μs) modulo

C01130

= 1750 μs

 Instant of acceptance/transmission of synchronous PDOs
 Inactive instant of acceptance
