3.1 General
The Motion Terminal VTEM provides a range of pneumatic open-loop and closed-loop control functions
that are executed in the form of Motion apps (MA). Parameters and setpoint values for executing a
Motion App can be specified. The Motion App converts these specifications into control commands at
the corresponding valve.

3.1.1.1 CPX terminal electronics side
The CPX terminal establishes the connection to a higher-order controller (è 6.1 Supported CPX bus
nodes) by means of an internal controller (CPX-CEC-...-V3) or a bus node.
3.1.1.2 Controller Motion Terminal CTMM-S1-C
The Motion Terminal controller forms the interface between the CPX terminal and the components of
the Motion Terminal.
The controller has an Ethernet interface for accessing the WebConfig user interface for the Motion
Terminal. Compressed air (1) and common exhaust or vacuum (3), as well as pilot exhaust air (84) and
pressure compensation (L) can be connected to the controller housing.
From the perspective of the CPX terminal, the Motion Terminal is a single component and is modelled
with a defined amount of input and output data in the process data of the CPX terminal è 3.5
Communication between PLC and Motion Terminal.
The terminal CPX and the CPX module CTMM-S1-C can be parameterised with the operator unit
(CPX-MMI), the Festo Maintenance Tool (CPX-FMT) software or the higher-level system.
Further information on the parameterisation of the CPX system and its modules can be found in the
CPX terminal manual è 1.1 Applicable documents.

Tab. 4: Description of the CPX module parameters
3.1.1.3 Manifold rail
The manifold rail provides the air ports (2) and (4) for each of the valves, as well as the ports for
compressed air supply (1) and common exhaust (3). In addition, the manifold rail can be connected
to an external pilot air supply (14). The changeover between internal and external pilot air is effected
using a blanking plug or selector in the manifold rail (è 1.1 Applicable documents Instructions for use
of the Motion Terminal VTEM).
3.1.1.4 Pilot pressure regulator
The pressure regulator ensures a constant pilot pressure for the valves.
The pressure regulator is set and sealed at the factory. The setting must not be changed; doing so will
invalidate the warranty.
3.1.1.5 Input module CTMM-S1-A/D-… (optional)
Individual Motion Apps include the evaluation of digital or analogue sensor signals. The sensors
necessary for this are connected to the CTMM input modules. The assignment of the inputs to a valve
and thus to a Motion App is done via the system parameters è 3.4.3.1 System parameters.

Festo — VTEM — 2021-05f
Function
The inputs are evaluated only by the controller of the Motion Terminal. The states of the inputs cannot
be queried directly by the higher-order controller. However, various Motion Apps provide information
about the states or values of the sensors.
The characteristics of the peripherals that are connected to the inputs of the input module must be
made known to the system (input module configuration).

3.1.1.7 Valves
The valves together with the controller form the central component of the Motion Terminal. A valve
VEVM-S1- 27-… in each case contains 4x 2/2-way dynamic control valves with piezo pilot valves
interconnected to form a full bridge. Each valve is additionally equipped with sensors so as to be able
to detect the actual status of the valve and regulate it.

One of the licensed Motion Apps can be run on each valve, independently of the other valves.
Numbering of the valves
The slots for the valves are numbered sequentially in ascending order from left to right, starting at the
right of the controller with slot 0. The number (address) of a valve is given by the slot on which it is
mounted.

3.1.4.2 Pneumatic
Ports for compressed air supply (1) and common exhaust (3) are available both on the controller and
on the right-hand end of the manifold rail. The ports are internally connected in each case and can be
used alternately or in parallel.
Ports (1) and (3) on the manifold rail should be selected for flow-intensive applications. For further
improvement an independent, parallel circuitry for both the supply and exhaust ports should be
selected. More information can be found in the support portal è www.festo.com/sp.
The product can be operated with internal or external pilot air.
–The pressure at port (1) must be > 3 bar for the internal pilot air supply.
–The pressure at port (14) must be > 3 bar for the external pilot air supply.
Pressure at port (1) is monitored by the device. If the pressure is less than 3 bar at port (1), an
external pilot air supply of at least 3 bar is required; the negative pressure monitoring at (1) must
be deactivated via the corresponding CPX module parameter è Tab. 3 Overview of the CPX module
parameters. The device does not monitor the pressure for port (14).
With external pilot air supply, it must always be maintained for the entire duration of operation. After a
pressure loss, a voltage reset is required before operation can be continued without error.

3.1.5 Definition of the direction of movement/position of the drive
In this document and on the WebConfig interface, the direction of movement or the position of drives
that are controlled by the Motion Terminal are generally described using the terms ‘advancing’ or
‘advanced’ and ‘retracting’ or ‘retracted’, respectively, which relate to piston rod cylinders with a
piston rod at one end. Depending on the pneumatic function, the meaning of the terms can be used for
other drives.

3.2 Firmware versions
Changes from one firmware version to the next can be found in the corresponding release notes, which
are provided with the firmware installation files in the Support Portal (è www.festo.com/sp). This
version of the manual refers to the following firmware version: è Tab. 2 Product version.
The device is updated to a new firmware version with the Festo Field Device Tool (FFT) (see Quick
Guide for the Motion Terminal VTEM è 1.1 Applicable documents). The device will subsequently func-
tion in accordance with the factory settings. If required, existing parameterisation data and settings
can be exported to a configuration file before a firmware update and re-imported once the update has
been completed (è 3.3.3 Export/import of parameterisation and settings).
3.3 WebConfig user interface
The Motion Terminal has a WebConfig interface for commissioning and functional testing.
It can be opened using a browser on a device connected to the Motion Terminal controller. It is not
possible to access the WebConfig interface for the controller using the Ethernet connection of a bus
node in the CPX terminal.
The settings, configurations and actual values of the Motion Terminal can only be viewed; they cannot
be changed without a password. The password must be entered via the menu bar of the WebConfig
and can be changed after successful authentication. A forgotten password can only be reset by
updating the firmware.

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.

3.3.3.1 Behaviour during export
Behaviour during export:
–The parameters of all existing valve slots are exported, as are the slots that do not have a valve
inserted at this point.
–The parameters of all five parameter sets are exported (with system, application, tuning parameters
and associated teach-in data) (è 3.4.3.9 Parameter sets).
–All sensor parameters (è 3.4.3.4 Sensor parameters) are exported as long as the corresponding
input module is actually available.
–The last saved status is exported for all parameters (via the WebConfig interface or the transfer
mode è 3.5.4.4 Saving settings as persistent data).
–All parameters for the description of user-defined peripherals are exported, if available è 3.4.3.5
Parameters for describing user-defined position sensors, è 3.4.3.6 Parameters for describing user-
defined flow sensors, è 3.4.3.7 Parameters for the description of user-defined drives.
3.3.3.2 Behaviour during import
Behaviour during import:
–Parameters and settings for which no value was exported retain their previous value for the import.
–When the parameterisation data is read in, the values are checked for permissible value ranges. If
the limits are violated, the parameter is set to the next critical limit.
When transferring a configuration file to a device with a different construction, the following must be
observed:
–Parameterisation data for valves are assigned according to their slot.
–When transferring from a longer device variant to a shorter one, the data of the "excess" valve
slots are ignored.
–When transferring from a shorter device variant to a longer one, data cannot be written for the
additional valve slots (with a higher slot number).
–Parameterisation data for input modules are assigned according to their input module position (1 or
2).
–As data for analogue and digital input modules are not compatible with one another, sensor
parameters can only be imported if the type of the assembled input module corresponds with
this position between the source and target device.
–It is possible to transfer input module parameterisation data between device variants of different
lengths (for example from 4 + 2 to 8 + 2, from 8 + 2 to 4 + 2, from 4 + 2 to 2 + 1, etc.).
