Table 8: Functionality of valves on IAC/IFB Multi-Ethernet basis
Function
Axis control function
Safety function
Ethernet communication
Valves on Multi-Ethernet basis can be connected to higher-level control systems
via Ethernet-capable bus systems (Sercos III, EtherCAT, EtherNet/IP, PROFINET RT,
POWERLINK or VARAN) and programmed using the IndraWorks Ds PC program.
The Ethernet-capable bus system must not be used to transfer safety-related
signals. These are to be provided or evaluated directly at the connector.
Valves based on Multi-Ethernet (with axis control) offer a wide range of
functionalities and operating modes like position/pressure/force/speed/flow
control and alternating controls (e.g. p/Q function). For additional information,
please refer to the valve-specific data sheets.

5.2 Product description

The valve on Multi-Ethernet basis is designed for use in harsh industrial
environments in terms of interference, mechanical vibration, shock and climate
resistance.
The valve provides freely configurable controller variants:
• E.g. position / pressure / force / velocity / flow controller
• Alternating control (e.g. flow/pressure, position/pressure)
Parameterization and diagnosis are handled using the PC software IndraWorks
Ds, which can be downloaded from https://www.boschrexroth.de/iac. This
enables individual parameterizing of the valve according to axis requirements.
For process connection, the valve is equipped with digital and analog encoder
interfaces and up to two freely configurable digital inputs/outputs. Communication
with the higher-level control is realized via an Ethernet-capable bus system.
For operation of the device, a higher-level control logic with appropriate I/O
components is additionally required, which, in conjunction with the valve,
holistically controls the motion sequence of the machine and also monitors it in
terms of safety. The bus system must not be used to transfer safety-related signals.
These are to be provided or evaluated directly at the connector.
The preparation of application-specific data sets forms the basis for the function
of the valve on Multi-Ethernet basis. These data sets are generated on the PC and
sent to the valve via Ethernet. The combination of user program and data sets is
called project.
The valve covers a wide range of controller functions which are described in the
respective valve-specific data sheet.
