“Port cycle time (n*0.1 ms)” parameter
The “Port cycle time (n*0.1 ms)” defines the cycle time of the
IO-Link port. This parameter is only relevant if the “Port cycle”
parameter has been set to “Fixed value”.
According to the IO-Link specification, the cycle time is
coded with a time base (2 bits) and a multiplier (6 bits). The
coding is dependent on the cycle time.
Coding the cycle time
Cycle time Time base Multipl. Calculation
0,4 ms ... 6,3 ms 0,1 ms 4 ... 63 Time Base × Multipl.
6,4 ms … 31,6 ms 0,4 ms 0 ... 63 6,4 ms + Time Base × Multipl.
32,0 ms … 132,8 ms 1,6 ms 0 ... 63 32,0 ms + Time Base × Multipl.
4 … 1326 (default: 4)
The cycle time of the IO-Link port set is (4 … 1326) × 0.1 ms.
Cycle times which cannot be coded as above, are
automatically converted by the IO-Link master
into the next-possible, codable time.
The web view is not updated.
“IO-Link device check” parameter
This function allows the identification characteristics of a
connected IO-Link device to be checked. The transfer of the
process data is only started once the characteristics match
the values set in the IO-Link master.
disabled (default)
The function is disabled and there is no validation.
Type compare
The Vendor ID and the Device ID are compared.
Identical
The Vendor ID, the Device ID and the serial number are com-
pared.
“DS activation state” parameter
The “DS activation state” activates the Data Storage func-
tion. The Data Storage function controls the parameter
setting server of the IO-Link master. The parameter setting
server manages the IO-Link device parameters, such that the
IO-Link master or a IO-Link device (from IO-Link specification
version 1.1) is very easy to replace.
disabled (default)
The Data Storage function is disabled. Parameter data al -
ready saved in IO-Link master is retained.
enabled
The Data Storage function is enabled. Parameter data is ex -
changed between the IO-Link master and IO-Link device if
an inconsistency is detected. The direction of replacement
depends on the status of IO-Link master and IO-Link device.
An upload of IO-Link device to the IO-Link master takes place
if a connected IO-Link device requests an upload (upload
flag set) or if there is no valid data in the IO-Link master. A
IO-Link device requests an upload for each change in the
IO-Link device parameter.
If the parameter data saved in the IO-Link master does not
match the data on the connected IO-Link device and there
have been no upload requests made by the IO-Link device,
data is downloaded from the IO-Link master to the IO-Link
device.
Data Storage function enabled
IO-Link master status IO-Link device status Action
No valid data Upload flag set Upload
No valid data Upload flag not set Upload
Valid data Upload flag set Upload
Valid data Upload flag not set Download
Clear
The Data Storage function is disabled. Parameter data al -
ready stored in the IO-Link master is deleted.
If the Data Storage function is enabled, do not
connect any IO-Link devices with unknown
parameters to avoid saving incorrect parameters.
Reset IO-Link devices to factory settings before
you connect them.
