Product description
General
The IFB Multi-Ethernet valve (Integrated Fieldbus) is a digital directional control valve with integrated fieldbus.
The following operating modes are possible:
- Standard:
- Valve direct control
- Flow control
- With external (version "00..D95") or internal pressure sensors:
- Pressure/force control
- Active damping
- Substitutional control (flow – pressure/force); pQ function (flow-controlled)
Communication is done via the digital Multi-Ethernet interface (X7E1 or X7E2) only. The following data may be exchanged:
- Command values
- Actual values
- Configuration and setting of the system control parameters
- Status messages, faults or warnings
Set-up
The directional control valve with IFB Multi-Ethernet electronics
mainly consists of:
- Main housing with control spool (1)
- Control electronics with integrated fieldbus (3)
- Connector, voltage supply, safety shut-down (XH1)
- Ethernet interfaces (X7E1, X7E2)
- Analog sensor interfaces (X2N), optional
- Pressure sensor sandwich plate (4), optional
- Stroke solenoid (2.1)
- Control solenoid with electrical position feedback (2.2)
Notice:
With version "V32", the control spool may rotate in case of single-sided flow through the supply flow edges (P–A or P–B) causing damage or failure of the valve. This can be solved by reduction of the pressure differential over the supply flow edge to a maximum of 80 bar or by simultaneous use of both control edges (P‒A/B‒T or P‒B/A‒T).
The integrated electronics (OBE) compares the specified command value to the position actual value. In case of control deviations, the relevant solenoid (2) will be activated and will compensate the COMMAND/ACTUAL difference by changing the solenoid force. Stroke/control spool cross-section is regulated proportionally to the command value. In case of a command value presetting of "0", the electronics adjust the control spool (1) to central position (zero flow).
Safety function
Thanks to the two control solenoids (enable pin D and E, low signal) at the connector (XH1), direction-dependent shut-off is enabled. The control spool of the valve is in spring-centered central position for this purpose (fail-safe position).
Enable acknowledgment pin C for solenoid A and pin F for solenoid B are "high". By connecting both control solenoids (enable pin D and E, high signal), the valve can be controlled by a command value presetting (command value positive, solenoid B or command value negative, solenoid A).
Enable acknowledgment pin C for solenoid A and pin F for solenoid B are "low".
Separate shut-off of solenoid A or solenoid B will moreover allow for the direction-dependent activation or shut-off of the drive.
Notice for safe shut-off according to EN 13849-1
(Enable acknowledgment)
The enable acknowledgment is not set (pin C and F):
- For failure of supply voltage.
- In case of a cable break (the integrated electronics (OBE) will de-energize both control solenoids and the control spool will move to the spring-centered central position).
- If the control spool is not in a hydraulically safe position (insufficient safety overlap of the control spool or safe position is not reached).
Safety function
The integrated electronics (OBE) of the valve enables the additional shut-off of a channel according to EN 13849-1 in both directions (depending on the symbol, the valve can be considered as safely shut-off).
When using symbol V, the valve cannot be used in a safety-relevant manner according to EN 13849-1.
Monitoring
The digital control electronics enable comprehensive monitoring functions/error detection including:
- Undervoltage
- Communication error
- Cable break for analog sensor inputs
- Monitoring of the microcontroller (watchdog)
- Temperature of the integrated electronics
IndraWorks DS PC program
To implement the project planning task and to parameterize the valve, the user may use the IndraWorks DS engineering tool (see accessories):
- Project planning
- Parameterization
- Commissioning
- Diagnosis
- Comfortable administration of all data on a PC
- PC operating systems: Windows 7-10
Notices:
- When using symbol V, V1, the enable inputs (enable pin D and E) may only be activated and deactivated together.
- For all other symbols, a unilateral shut-off will cause reduced performance data.
- 4/3 directional control valves do not have a leakage-free basic locking when deactivated. Leakage must be considered when designing the drive.
- Valve type 4WRPF can be used as shut-off element cat. 3 or 4 (up to PL e according to EN 13849-1). For both categories, an additional shut-off element is required to achieve a two-channel shut-off. For further information on the safety application, see operating instructions 29391-B.

Detailed description of the safety function:
After the signal at the enable input has been removed, the output stage, and thus the solenoid of the valve, are internally separated from the available supply voltage. The enable acknowledgment will only be activated after the safe valve spool position has been achieved.
For a detailed description of the safety function, refer to the operating instructions 29391-B.

Project planning information
Project planning and maintenance instructions
- The supply voltage must be permanently connected, as otherwise bus communication is not possible.
- If electro-magnetic interference is to be anticipated, suitable measures must be taken to ensure the function (depending on the application, e.g. shielding, filtration).
- The devices have been tested in the plant and are supplied with default settings.
- Only complete devices can be repaired. Repaired devices are returned with default settings. User-specific settings will not be applied. The machine end-user will have to retransfer the corresponding user parameters.
