Basic safety instructions
2 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any
• eventualities and events which may occur during installation, operation and maintenance of the devices.
• local safety regulations which the operator is responsible for observing, also in relation to the installation personnel.
DANGER!
Danger from high pressure!
`Before loosening lines and valves, turn off the pressure and vent the lines.
WARNING!
Danger due to electric voltage!
`Before reaching into the system (apart from the teach-in procedure in a non-explosive atmosphere), switch
off the voltage and secure to prevent it from being switched on again!
`Observe the applicable accident prevention and safety regulations for electrical equipment!
General hazardous situations.
To prevent injuries:
`Ensure that the system cannot be activated unintentionally.
`Installation and maintenance work as well as operator actions may only be carried out by authorized and suit-
ably qualified technicians using the appropriate tools.
`Do not make any unauthorized internal or external changes to the device!
`The process is restarted in a defined or controlled manner after an interruption in the power supply or pneu-
matic supply.
`The device may be installed and operated only when in perfect condition and in consideration of the operat-
ing instructions.
`The general rules of technology apply to application planning and operation of the device.
NOTE!
Electrostatic sensitive components / modules!
• The device contains electronic components which are sensitive to electrostatic discharge (ESD). Contact with
electrostatically charged persons or objects may be hazardous to these components. In the worst case scenario,
they will be destroyed immediately or will fail after start-up.
• Observe the requirements in accordance with EN 61340-5-1 to minimise or avoid the possibility of damage
caused by a sudden electrostatic discharge!
• Ensure that you do not touch the electronic components when the power supply voltage is applied!

Basic safety instructions
NOTE!
Risk of damage to property!
• Do not connect any mechanically rigid connection parts, in particular those with long lever arms, as such con-
nections could generate torques that might damage the control head.
• Do not supply the medium connections of the system with liquids or aggressive or flammable media!
• Do not subject the housing to mechanical loads (e.g. by placing objects on it or standing on it).
• Do not make any unauthorised external changes to the housings of the device. Do not paint housing parts or
screws.
• Only use compatible cleaning agents for cleaning the securely closed control head and always rinse thoroughly
with clean water.

General information
3 GENERAL INFORMATION
These Additional Instructions are an supplement to the basic operating instructions for Type 8681.
They only describe the extensions and specifications for Type 8681 büS/CANopen.
“büS” (Bürkert system bus) stands for the communication bus developed by Bürkert and is based on the
CANopen protocol.
The following examples refer to the application of the EtherNet/IP protocol using a Bürkert gateway. The following
bus systems are also supported by the Bürkert Gateway:
PROFINET, Modbus/TPC, PROFIBUS DPV1, EtherCAT, CC-Link - corresponding configurations on request.
3.1 Conformity / Standards
The Control Head Type 8681 büS/CANopen complies with the EU directives according to the EU Declaration of
Conformity.
The applied standards, which are used to demonstrate compliance with the EU Directives, are listed in the EU
Prototype Examination Certificate and/or the EU Declaration of Conformity.
3.2 Approvals
The Control Head Type 8681 büS/CANopen is not authorised for those application areas which are described by
the ATEX Directive and the directives for the Underwriters Laboratories (UL) and Factory Mutual (FM).

Quickstart for initial start-up
4 QUICKSTART FOR INITIAL START-UP
“büS” (Bürkert system bus) stands for the communication bus developed by Bürkert and is based on the CANopen
protocol. The following steps refer to the application of the e.g. EtherNet/IP protocol using a Bürkert gateway pre-
configured for a maximum of 63 control heads.
For other gateway configurations (e.g. in conjunction with ELEMENT positioners), the specific documentation for
preconfigured Bürkert gateways must be observed.
After mounting the control heads (Type 8681 büS/CANopen) in the network, the following operations must first
be carried out on the control heads:
1.) Addressing of the control heads
According to chapter “6.13.2 Setting the büS/CANopen address (Node ID)” each control head in the network must
be assigned its own unique address (Node-ID).
When using a preconfigured gateway: For easy commissioning, each control head should be assigned its unique
node ID between 1 and 63 using the DIP switches. This allows the preconfigured communication settings between
the gateway and each control head to be used. The factory setting (address “0” = softwareconfigurable address/
node ID) should not be used furthermore.
When using a non-pre-configured gateway or when using the factory setting “0” (software-configurable
address/node ID): A device configuration via Bürkert Communicator on site is required for commissioning each
control head (see also section “6.13.3” on page 36 ).
Error-free parameter access by the Logix Designer: To ensure this, the new addresses should be selected
clearly arranged and in sequence (starting with “1” and without gaps in the numerical series!).
Any change of the device address requires a device restart.
2.) Setting the baud rate
Set the baud rates according to chapter “6.13.1 Setting the baud rate”. The combination of cable lengths and baud
rate is very important (see chapter “6.5.2 Total line length and drop line lengths of the bus cables”).
The baud rate of all devices connected to the network (including the gateway) must be the same .
Any change of the baud rate requires a device restart.
3.) “Hiding” of non-existent devices
If less than 63 devices are assigned to the gateway, the non-existent devices must be “hidden” at the gateway, both
outputs AND inputs - see chapter “6.17 Configuration of the control head network”, either using the Logix-Designer
(“6.17.1”) or Bürkert Communicator (“6.17.2”).
After the changes have been made, a device restart is required.
4.) Careful closing of the electrical connections
Due to moisture (including steam) in the system, all electrical connections (M12 plug-in connections) must be
firmly screwed on with 0.6 (+0.1) Nm. All open electrical connections must be well “sealed” with protective
caps (see information box in chapter “6.2 Network principle / Interfaces” and also chapters “7 Accessories” and
“8 Cabling examples”.
