Dev-Ack-LPSDO
(acknowledgment)
The register for acknowledging the IC220SDL953 has the following structure and function:
S:
To start a project with a quick start, proceed as follows:
1. Initialize registers 4 to 7 of the IC220SDL953 (short protocol) with 0.
2. Set bit S to 1.
3. Write the project header CRC to registers 4 to 7 of the IC220SDL953.
App-Diag-LPSDO
(application diagnostics)
The bits in this register can be freely programmed in VersaConf Safety. Implement diag-
nostics using these bits.
The IC220SDL953 register has the following structure and function:
