Commissioning instructions
The following steps enable rapid commissioning of an AS-i network with the KL6201/KL6211 AS-i master terminal:
- Address the AS-i slaves.
- Connect the AS-i slaves to the KL6201/KL6211.
- In delivery state the KL6201/KL6211 is set to the 12-byte process image, which supports direct access to the process data of AS-i slaves 1 to 11. A larger process image is required for direct access to further AS-i addresses.
![]() | Enabling process data communication For enabling process data communication, set bit 3 in the AS-i command nibble (ASI CN in byte 6) to 1bin. |
Example for the 12-byte process image:
Parameter data block | Process data block | ||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|
Byte 0 | Byte 1 | Byte 2 | Byte 3 | Byte 4 | Byte 5 | Byte 6 | Byte 7 | Byte 8 | Byte 9 | Byte 10 | Byte 11 |
CB0 | CB1 | ParaOut0 | ParaOut1 | ParaOut2 | ParaOut3 | ASI CN + ASI Out Slave 1 | ASI Out Slave 2+3 | ASI Out Slave 4+5 | ASI Out Slave 6+7 | ASI Out Slave 8+9 | ASI Out Slave 10+11 |
0x00 | 0x00 | 0x00 | 0x00 | 0x00 | 0x00 | 0x8p | 0xpp | 0xpp | 0xpp | 0xpp | 0xpp |
Key
ASI CN: AS-i command nibble
p: process data nibbles (outputs) for the respective AS-i slaves
CB n: control byte n
Para Out n: Output parameter, byte n
5. Once the AS-i cycle is completed, the KL6201/KL6211 responds with the input data (delayed by one or several cycles, depending on the higher-level fieldbus system).
![]() | Short-circuiting the two set inputs is not necessary for operation Short-circuiting of the two set inputs is not required for operation. During the commissioning phase this would in fact be a hindrance, since the KL6201/KL6211 would then only include those AS-i slaves in the data exchange that were found during short-circuiting of the set inputs. |
