Register description
The registers are used for parameterization of the terminal and can be read or written via the register communication.
Registers 0 to 31 always have the same meaning. The contents of registers 32 to 63 are specified via the register page selection register (R4).
R4: Register page selection register
This register specifies which register page is displayed in registers R32 to R63 of the KL6224 (default: 0x0000).
The register pages provide access to the IO-Link configuration, diagnostics and parameterization of the KL6224.
R8: Terminal description
Register R8 contains the terminal identifier in hexadecimal coding: 0x1850 (6224dec)
R9: Firmware version
Register R9 contains the firmware revision level of the terminal in hexadecimal coding, e. g. 0x0100 (256dec).
R10: Shift register length
0x0160
R11: Number of signal channels
0x0160
R12: Minimum data length
0x6060
R13: Data structure of the Bus Terminal
Register R13 contains the data structure of the Bus Terminal.
R15: Alignment register
R31: Code word register
The code word register of the KL6224 has no function for the user, since all settings that are specified via registers R32 to R63 (register pages) immediately take effect in the KL6224.
Register pages
In registers R32 to R64 the KL6224 shows the IO-Link configuration, diagnostics and parameterization of the register page selected with register R4.
Register page 2 (RP2)
Write 2 into the register page selection register R4 to facilitate access to register RP2.R32.
RP2.R32
This register specifies the size of the process image of the KL6224.

Value | Process image | Default |
|---|---|---|
0002hex | 12-byte process image (6 bytes parameter interface and 6 bytes IO-Link process data) | 0004hex |
0004hex | ||
0005hex | ||
0006hex | ||
further | reserved |
After changing the process image the Bus Coupler must be restarted for the modified process image to take effect.
