9.12 Device-specific parameters
The parameters of the device are set using an IO-Link parameter setting program (for example ifm
moneo).
More information about the IODD at www.ifm.com.
9.12.1 Parameter “Data Hold Time”
The data hold time indicates the time during which the data of the process data input image can be
held constant. Depending on the operating mode, this affects the EPC (“SINGLE EPC” and “EPC
REPORT” operating modes) and the data in the “READ DATA AUTO“ (Ò Operating Mode “READ
DATA AUTO"/20) and “WRITE DATA AUTO“ (Ò Operating Mode “WRITE DATA AUTO"/21)
modes.
After the data hold time has elapsed, the device automatically confirms the data: the block counter in
the process data input image is increased. Then the next data is transferred.
The data hold time is cancelled by manually incrementing the block counter in the process data output
image. Then the next data is transferred.
The parameter does not affect data transmission in the following operating modes:
- “EPC LIST” (Ò Operating mode "EPC LIST/25)
- “WRITE EPC“ (Ò Operating mode "WRITE EPC”/26)
- “READ DATA“ (Ò Operating mode "READ DATA/29)
- “WRITE DATA“ (Ò Operating mode "WRITE DATA”/32)
- “LOCK DATA“ (Ò Operating mode "LOCK DATA”/35)
9.12.2 Parameter "Auto-Read/Write Address"
In the operating mode “READ DATA AUTO” (Ò Operating Mode “READ DATA AUTO"/20) / “WRITE
DATA AUTO” (Ò Operating Mode “WRITE DATA AUTO"/21), the device reads / writes a specified
number of data bytes.
The parameter defines the address in the memory area which is accessed during the read and write
operation. The address is indicated in bytes from the start of the memory area.
The data is processed as a data word (2 bytes).
u Use data word as format for the address.
u Use only even addresses.
The addressed memory area for the read and write operation cannot be outside the memory
area of the device:
u auto-read/write address + data length for auto-read and auto-write ≤ number of available
bytes on the device
9.12.3 Parameter "Auto-Read/WriteData Length"
In the operating mode “READ DATA AUTO” (Ò Operating Mode “READ DATA AUTO"/20) / “WRITE
DATA AUTO” (Ò Operating Mode “WRITE DATA AUTO"/21), the device reads / writes a specified
number of data bytes. The parameter defines the length of the memory area which is read and written
from the device in bytes.
The data is processed as a data word (2 bytes).
u Specify the data length as a multiple of 2 bytes.
