•
Type-compatible IOL device (V1.0)
Type-compatible according to IO-Link specification V1.0
•
Type-compatible IOL device (V1.1)
Type-compatible according to IO-Link specification V1.1; "Manufacturer identifier" and
"Device ID" are checked by the IOL master
•
Type-compatible IOL device (V1.1) with "Backup and Restore"
Type-compatible according to IO-Link specification V1.1; "Manufacturer identifier" and
"Device ID" are checked by the IOL master with "Backup and Restore." The connected
IOL device must be type compatible for the "Backup and Restore" function.
•
Backup (device to master)
A backup (upload / from IOL device to IOL master) is performed if an IO-Link device is
connected and the master has no valid data. The parameter data that is read is perma-
nently stored on the master. If parameter data is changed on the device during runtime,
the device parameter stored on the master can be updated using the
ParamDownload-
Store
command (index 0x0002, subindex 0x00, value 0x05). This command sets the
flag
DS_UPLOAD_REQ
on the device so that the IOL master performs an upload from
the IOL device. For each new connection to an IO-Link device, the master compares the
stored parameter data with the device data. If the function is not active on the device
(parameter storage "locked"), the master will download the stored data onto the device
where there are discrepancies. The IO-Link master can be replaced using the "Backup"
function.
•
Restore (master to device)
Parameter data can be transferred to an IO-Link device only if parameter data is available
on the IOL master parameter server and can be used for the device. When an IOL device
is connected, the master compares the stored parameter data with the IOL device data. If
the function is not active on the device (parameter storage "locked"), the master will
download the stored data onto the device where there are discrepancies. If the master
has not stored a device parameter set, nothing happens.
The IO-Link device can be replaced using the "Restore" function.
Default: no IOL device check
Port Cycle Time
The "IO-Link Manual" port mode is required for the "Port Cycle Time" option.
•
As fast as possible
For the cyclic IO data update between the IOL master and IOL device, the IO-Link master
uses the maximum supported IOL device update cycle time, which is limited by the maxi-
mum supported IOL master cycle time.
Action
IO-Link master status
IO-Link device status
Backup
Valid data (or deleted)
Upload flag active (valid data)
Backup
Invalid data (or deleted)
Upload flag not active & valid data
Backup
Valid data
Upload flag active & valid data
Restore
Valid data
Upload flag not active (data is the same)
Table 5.2
Note
If the parameters were written to the IO-Link device in block mode, an IO-Link device sets the
"Upload" flag independently.
