Data exchange

For communication via CIP Safety™, the safety option (target) must be connected to a fail-safe controller (F-originator) via EtherNet/IP™.

CIP Safety™ data exchange with MOVISAFE® CSB..A

The CSB..A safety options have the module designation "Safety Output" and "Safety Input" with the following process data assignment for data exchange between the safety option and a fail-safe controller via CIP Safety™:

  • "Technology" profile variant
    • 16 bytes input data
    • The first 4 bytes contain the user data from the FS protocol profile; the remaining bytes are required for the safety IO connection.
    • 14 bytes output data
    • The first 3 bytes contain the user data from the FS protocol profile; the remaining bytes are required for the safety IO connection.
CIP Safety™ data exchange with MOVISAFE® CSL..A/CSS..A

The CSL..A/CSS..A safety option has the module designation "Safety Output" and "Safety Input" with the following process data assignment for data exchange between the safety option and a higher-level controller via CIP Safety™:

  • "Technology" profile variant
    • 20 bytes input data
    • The first 6 bytes contain the user data from the FS protocol profile; the remaining bytes are required for the safety IO connection.
    • 18 bytes input data
    • The first 5 bytes contain the user data from the FS protocol profile; the remaining bytes are required for the safety IO connection.

Profile data must be evaluated and provided in CIP Safety™ in "Little Endian" notation.
