Siemens SINAMICS SIMOTICS S200 PROFINET - Page 492

Acknowledgment: NONE
Cause: The bus is in the data exchange state and clock synchronous operation has been selected using the parameterizing
t
elegr
am.
The synchronization telegram is irregularly received.
- The controller sends an irregular synchronization telegram.
- The controller uses another isochronous bus clock cycle than was transferred to the device in the parameterizing telegram.
Remedy: - Check the controller application and bus con󹪝guration.
- Chec
k the consistency between the clock cycle input when con󹪝guring the device and clock cycle setting at the controller.

A01944 PN: Sign-of-life synchronism not reached
Message class: Communication error to the higher-level control system (9)
Message value: -
Component: None
Response: NONE
Acknowledgment: NONE
Cause: The bus is in the data exchange state and clock synchronous operation has been selected using the parameterizing
t
eleg
r
am.
Synchronization with the controller sign-of-life (STW2.12 ... STW2.15) could not be completed because the sign-of-life
changes di󹪜erently to how it was con󹪝gured in the Tmapc time grid.
Remedy: - Ensure that the controller correctly increments the sign-of-life in the controller application clock cycle Tmapc.

F01950 PN: Isochronous operation, synchronization unsuccessful
Message class: Communication error to the higher-level control system (9)
Message value: -
Component: None
Response: OFF1
Acknowledgment: IMMEDIATELY
Cause: Synchronization of the internal clock cycle to the controller clock cycle has failed. The internal clock cycle exhibits an
une
xpected shif
t.
Remedy: Only for internal Siemens troubleshooting.

A01980 PN: cyclic connection interrupted
Message class: Communication error to the higher-level control system (9)
Message value: %1
Component: None
Response: NONE
Acknowledgment: NONE
Cause: The cyclic connection to the PROFINET controller is interrupted.

Remedy: Establish the PROFINET connection and activate the PROFINET controller in the cyclic mode.
Check parame
ters "Name of Station" and "IP of Station".
A01981 PN: Maximum number of controllers exceeded
Message class: Error in the parameterization / con󹪝guration / commissioning pr
