Parameter data block (byte 0 to 5 of the process image)

All AS-i parameters of the KL6201/KL6211 can be accessed via bytes 0 to 5 of the process image interface. The output and input data are then assigned as follows:

Output parameters (PLC -> KL6201/KL6211)

A new task is detected, if one of the bits in the 6-byte parameter data block has changed.

Byte	Bit	Description
0 (CB0)	0 to 5	Parameter number bit 0 to 5
	6	0_bin: Read 1_bin: Write
	7	Always 0 (due to compatibility with register communication)
1 (CB1)	0 to 3	Parameter number bit 6 to 9
	4	Only relevant for write with masked access: 0_bin: Low word (bit 0 to 15) is addressed 1_bin: High word (bit 16 to 31) is addressed
	5	Only relevant for write: 0_bin: Normal 32-bit access 1_bin: Masked 16-bit access with 16-bit mask (only those bits are changed whose mask is set to "1")
	6	0_bin: Parameter access is locked 1_bin: Parameter access:
	7	always 0
2 (ParaOut0)	0 to 7	Read: free Write (normal): Parameter value bits 0 to 7 Write (masked): Parameter value bits 0 to 7
3 (ParaOut1)	0 to 7	Read: free Write (normal): Parameter value bits 8 to 15 Write (masked): Parameter value bits 8 to 15
4 (ParaOut2)	0 to 7	Read: free Write (normal): Parameter value bits 16 to 23 Write (masked): Mask bits 0 to 7
5 (ParaOut3)	0 to 7	Read: free Write (normal): Parameter value bits 24 to 31 Write (masked): Mask bits 8 to 15

Input parameters (KL6201/KL6211 -> PLC)

Byte	Bit	Description
0 (SB0)	0	Only relevant in protected mode: 1_bin: The set configuration and the actual configuration match
	1	1_bin: A power failure has occurred
	2	1_bin: automatic addressing is enabled (protected mode must be active) 0_bin: automatic addressing is locked: an AS-i slave with address 0 was found, but no projected AS-i slave is missing or a non-projected AS-i slave was found
	3	1_bin: automatic addressing is available (protected mode must be active and precisely one projected AS-i slave must be missing)
	4	1_bin: an AS-i slave with address "0" was found
	5	reserved for extensions
	6	Diagnostic bit, 1_bin: a power failure has occurred in protected mode, the set configuration does not match the actual configuration, or an AS-i slave with the address 0 was found, or automatic address programming in the output data (byte 1, bit 5) was enabled by the controller but is locked at the AS-i master (input data byte 0, bit 2), or
	7	always 0 (for compatibility with register communication)
1 (SB1)	0	0_bin: the AS-i master responds to a read command 1_bin: the AS-i master acknowledges a write command
	1	0_bin: the AS-i master operates in projecting mode 1_bin: the AS-i master operates in protected mode
	2	the AS-i master is set to offline phase (the outputs of the activated AS-i slaves are set to the default value (1_bin), the inputs of the activated AS-i slaves in the controller were also set to the default value (0_bin)
	3	1_bin: the AS-i master operates in normal mode (data exchange phase was reached, AS-i outputs and AS-i inputs have the current values)
	4	Toggle bit, this bit toggles after each executed task
	5	0_bin: Parameter access was completed successfully 1_bin: Error during parameter access
	6	Acknowledges bit 6 of CB1: 0_bin: Process data mode 1_bin: Parameter access
	7	always 0_bin
2 (ParaIn0)	0 to 7	Read (without error): Parameter value bits 0 to 7 Write (without error): read parameter value bits 0 to 7 Read or write (with error): Error code bits 0 to 7
3 (ParaIn1)	0 to 7	Read (without error): Parameter value bits 8 to 15 Write (without error): read parameter value bits 8 to 15 Read or write (with error): Error code bits 8 to 15
4 (ParaIn2)	0 to 7	Read (without error): Parameter value bits 16 to 23 Write (without error): read parameter value bits 16 to 23 Read or write (with error): Error code bits 16 to 23
5 (ParaIn3)	0 to 7	Read (without error): Parameter value bits 24 to 31 Write (without error): read parameter value bits 24 to 31 Read or write (with error): Error code bits 24 to 31
