Manual Override; Access Control; Export/Import Of Parameterisation And Settings - Festo VTEM Manual

Function
Factory settings of the controller:
• IP address: 192.168.4.2,
• Subnet address: 255.255.0.0
• Password for activating edit mode: vtem
The password can be changed via the WebConfig interface.
Operation of the WebConfig interface is described in the "Motion Terminal VTEM, WebConfig interface"
Quick Guide è www.festo.com/sp.
3.3.1

Manual override

To enable testing of the functionality of a connected drive, the WebConfig interface has a "manual
override" that makes it possible to use the basic logic function of the valves without using a Motion
App.
The manual override is also used to test the tubing connection and direction of movement of the drive
è 3.1.5 Definition of the direction of movement/position of the drive.
3.3.2

Access control

Write access to a valve is possible at a certain time using either the WebConfig interface or the
higher-order controller (PLC). As standard, the PLC has the write access rights, but they can be actively
copied from the WebConfig interface.
Copying of the write access rights via the WebConfig interface is only possible if the valve is inactive
(ValveMode = 61) è Tab. 46 Status of the valve. This means that a running Motion App or transfer
mode must be terminated before the WebConfig interface obtains write access to the valve.
3.3.3

Export/import of parameterisation and settings

Parameters and settings saved on the controller can be exported in the form of a single file from the
device and then re-imported to the device. This includes the relevant data of all device components
(controller, valves, input modules).
Possible applications:
– Exporting before a firmware update, then re-importing to be able to continue to use parameters and
settings after the update ("Backup and Restore")
– Exporting the data from one device and importing to another device ("cloning" the terminal)
This file is exported and imported via the WebConfig interface, which can be found in the "Mainte-
nance" tab. Exporting and importing are only possible if none of the valves are in operation at this
time or data are currently being exchanged with the higher-order controller.
This means:
– The status of the valve (valve state) must not be Running for all valves (è 3.5.2.2 Structure of the
input data (PDI)).
– Transfer mode cannot be active for any of the valves (è 3.5.4 Transfer mode).
While the configuration is being accessed by the export function (reading) or by the import function
(writing), no other actions are possible via the WebConfig interface. Control via the output data of the
higher-order controller is also blocked until the access process has been completed.
An exported configuration file has the file name "VTEM_config_<Product Key>.csv". To aid orientation
for the user, the name includes the Product Key of the controller from which the data was exported.
The file can, however, be renamed without impacting usability for the import.
