4.3.3 Maximum cycling rate
In practice the cycling rate should be lower than 300 c.p.m. (<5 Hz). The valves should be switched above 90% (working port) and below 10% (exhausting port) of the supply pressure.
4.3.4 Minimum impulse on bistable valves
The minimum impulse length on 5/2 way bistable valves should correspond at least twice to the response time (see section
4.3.1).
4.3.5 Important information for 2x2/2 valves
All 2x2/2 functions (NC, NO or NO/NC) have port 1 not connected in neither end position to port 2 or 4. Port 1 is not necessary (except internal pilot air). Supply of compressed air or vacuum must be feeded to port 3 or 5.
Pay attention to this when configuring the valve island (blanking off canals 3 and 5 in base) !!

5.1.6 Internal/external pilot air supply
The position of the gasket between valve body and pilot valve defines and indicates pilot air supply. Conversion between internal and external pilot supply occurs by flipping the red gasket.
Internal pilot air supply (fig. 1): from port 1 External pilot air supply (fig. 2): from port 12/14
In any case pilot exhaust air is collected and exhausted via port 82/84.
Figure 1 Figure 2
Solenoid 12 Solenoid 12
Solenoid 14 Solenoid 14
Such conversion in the field should occur only when minimum operating pressure is not available at port 1. In these applications, the minimum operating pressure (or higher) is required at port 12/14 on the end plate.
Note:
After flipping the gasket, data on the valve label (symbol and part number) are no longer accurate. Furthermore, when changing valves or accessories (valve function, sandwich plate, etc.) on a valve island, the part number on the label will no longer correspond to the configuration. If you order the valve island based on the Norgren part number, the original configuration will be delivered.

8.1 GENERAL INFORMATION
VS18/VS26 Fieldbus valve islands range from a minimum of four valve stations to a maximum of 16 valve stations (32 solenoids). The exception to this rule is AS-Interface (see section Please refer to section
VS18/VS26 valve islands are available with below listed Fieldbus protocols. Please refer to the indicated section for detailed information on these protocols.
• Profibus DP Section
• DeviceNet Section
• CANopen Section
• Interbus-S Section
• AS-Interface Section
• FD67 bus Section
VS18/VS26 Fieldbus valve islands contain electronic devices, which could be damaged through electrostatic discharge. Therefore electrostatic precautions must be taken. Specifically, the person assembling or configuring the valve island must be connected to an earth ground.
The valve island should be mounted on an earthed base to improve the EMC behaviour.

8.1.1 Power supply and pin assignment
VS18/VS26 Fieldbus valve islands are designed to be used with a protective extra low voltage (PELV) power supply (UL Class 2 Supply only) according to IEC 364-4-41. As a result, an earth connection for safety reasons is not required because the supply voltage is restricted to a maximum of 42.2 volts even under fault conditions. However, the earth must be connected. It is not a protective earth, but is required to provide EMC shielding.
The power supply of the Fieldbus valve islands (excluding the version with AS-Interface or FD67 bus) are made by an 4-pin M12 connector. Using Profibus DP, a 5-pin 7/8“ connector is also available.

8.2.2 Profibus DP wiring
The bus line is specified in EN 50170 as line type A. It can be used as shown in the following table. The table gives the bus parameters and line lengths of A and B type lines for comparison. However it is recommended that only type A lines should be used, due to their expanded length capabilities.

Calculating possible line lengths
The maximum admissible distance between two bus stations in each Profibus network can be calculated as follows:
(NO_REP + 1) * Segment length
NO_REP = The maximum number of repeaters connected in series (depends on repeater type).
Example: The repeater manufacturer’s specifications allow nine repeaters to be connected in
series. The maximum distance between two bus stations at a data transfer rate of 1’500 kBit/s is then as follows: (9 + 1) * 200 m = 2’000 m

VS18/VS26 MAINTENANCE & INSTRUCTION BOOKLET
Wiring termination
The active bus termination using a resistor combination avoids signal reflections during data transfer and ensures a defined zero-signal voltage on the data lines when none of the stations on the bus are active. Active termination must be provided at the beginning and end of each RS485 bus segment.

Line termination of wire A in acc. With EN 50 170
If the bus termination is missing, this can cause errors during data transfer. Problems can also arise if too many bus terminators are fitted since each bus terminator also represents an electrical load and reduces the signal levels and thus the signal-to-noise ratio. Too many or missing bus terminators can also cause intermittent data transfer errors, particularly if the bus segment is operated close to the specified limits for maximum numbers of stations, maximum bus segment length and maximum data transfer rate.
The power required by the active bus termination is usually obtained through the bus connector from stations connected to the bus. Alternative measures must be taken if there is no guarantee that the power required by the bus termination is permanently provided while the bus is operating. For example, in a particular installation the station providing the power to the bus termination may need to be repeatedly switched off or removed from the bus for operational reasons. In such cases, the bus termination should use an external power supply or a repeater should be used for bus termination instead.

8.2.3 Profibus DP address and baud rate setting
The VS18/VS26 Profibus DP valve island address can be set within the range 1 to 99 (rotary switch) resp. 125 (software). To set the address, use the selector switches accessible by removing the securing screw and lifting the hinged cover of the address switches. The two rotary switches allow an address range of 1 to 99. The valve island needs a power reset to accept a new address. When position 0 is selected on both switches the address may be set through software via a capable master.
Default address = 125
Following are VS18/VS26 Profibus DP baud rates, which are detected automatically:

8.2.5 Diagnostics
The VS18/VS26 Profibus DP slave uses diagnostic telegrams as a high-priority response to inform a master of its current state. The first 6 bytes contain the information specified by the standard e.g. status of the state machine, correct/incorrect parameterisation and configuration. Additionally, there is 1 byte of user diagnostics, which is used to show the state of the VA for the valves. By monitoring the first bit of the user diagnostics byte the presence of the valve power can be determined.
8.2.6 Profibus DP LED indicators

8.2.7 Profibus DP commissioning
Due to the increasing number of compatible master controllers it would be impractical to create detailed instructions for commissioning the Norgren node on a particular master. All Norgren Profibus products are conformance tested to the latest specification by an independent authorised test site and are fully certified by the Profibus International Group. As a result, the help guide and manual supplied with the users chosen PLC should be used during the commissioning stages of each Norgren node.

8.2.8 GSD file
A GSD file is used to identify a Profibus DP/PA device (master or slave). It contains data making it possible to have manufacturer independent configuration tools. Typical information in a GSD file is vendor information, baud rates supported, timing information, options/features supported and available I/O signals. A GSD file must be available for every DP/PA slave. This is installed into the PLC configuration software loaded into the products catalogue, in the additional field devices section.
8.2.9 Profibus DP valve island expansion
The modular design of the VS18/VS26 valve island allows easy modifications to the number of valves while in the field. The system allows single station expansion for up to 4 valve stations. For more information please refer to section
The VS18/VS26 Profibus DP valve islands may have to be reconfigured after expansion to accept the new number of valves. This is controlled by the DIP switch on the Fieldbus PCB (see section
8.2.4).

8.3.7 DeviceNet EDS files and commissioning
The electronic data sheet (EDS) library is a collection of EDS files that can be registered with RSNetWorx for Allen Bradley PLC’s and Compbus/D configurator for Omron PLC’s.
The EDS files, which are provided by Norgren and other manufacturers, contain configuration and identification information for the devices. RSNetWorx for DeviceNet software can access only those devices that have been registered. You must use the EDS Wizard within RS Networx for registering EDS files for unknown devices, or if you have updated EDS files to install. To install a new EDS file to your PLC please refer to the PLC manufacturers instruction manual or online help.
Although you receive a large number of electronic data sheet (EDS) files with the configuration software for DeviceNet, there may be a time when you need to acquire other manufactures EDS files from the ODVA www.odva.org (Open DeviceNet Vendor’s Association) web site.
DeviceNet node commissioning tool (RS Networx Only)
The DeviceNet node commissioning tool lets you commission, that is, set the node address and the baud rate parameters of, devices that are either connected to a DeviceNet network, or via a point-to-point connection.
Before you can add any node to a live DeviceNet network, it must be commissioned. This means that a node address and a baud rate must be programmed into the device. All Norgren VS18/VS26 nodes are preset with a node address, which is usually set to 63, unless otherwise stated by the user in the valve island configuration. These preset values will need to be changed to meet your application needs. Once a device has been commissioned and attached to a network, you can use the RSNetWorx for DeviceNet node commissioning tool to edit the node address that was set previously. Some devices do not permit software setting of the node address or baud rate. Refer to the device documentation for specific information.
Tip
For example, if two of the devices on your network are a photoelectric sensor and a hand controller and you accidentally change the node address of the hand controller to be the same as that of the photoelectric sensor, then the hand controller will no longer have a unique address. This means that it will not be able to communicate on the network. If you cannot access a device because you have used its node address for another device, you will have to remove it from the network, re-commission it and then reinstall it on the network.

8.4.3 CANopen address and baud rate setting
The VS18/VS26 CANopen valve island address can be set within the range 0 to 99 (rotary switch) resp. 127 (software). To set the address, use the selector switches accessible by removing the securing screw and lifting the hinged cover of the address switches. The two rotary switches allow an address range of 1 to 99. The valve island needs a power reset to accept a new address. When position 0 is selected on both switches the address may be set through software via a capable master.
Default address = 127
Changing the address of the node via software:
Using a CANopen configuration tool connected to the network, the address of each node maybe changed by the following method:
Send an SDO Telegram command to the node at SDO index 2100h containing the new node address, valid range 1-127. View example of SDO message below
Description SDO Index Sub Index Value

8.6.11 AS-Interface commissioning
Due to the increasing number of compatible ASi 2.11 master controllers it would be impractical to create detailed instructions for commissioning the Norgren node on a particular master. All Norgren AS-Interface products are conformance tested to the latest specification by an independent authorised test site and are fully certified by the AS-Interface international group. Because of this, the help guide and manual supplied with the users chosen PLC should be used during the commissioning stages of each Norgren node.
8.6.12 AS-Interface valve island expansion
The modular design of the VS18/VS26 valve islands allows easy modifications to the number of valves while in the field. The AS-Interface system allows a single station expansion according to the indicated configurations (see section section
The VS18/VS26 AS-Interface valve islands may have to be reconfigured after expansion to accept the new number of valves and correct allocation of the output bits. This is controlled by the DIP switch on the Fieldbus PCB (see section
9.
8.6.5 and 8.6.7). Fore more information please refer to

9 VALVE ISLAND EXPANSION
9.1 GENERAL INFORMATION
A configured Multipole or Fieldbus valve island is single step expandable up to a maximum of 4 additional valve stations. Confirm your valve island has not used any additional stations before proceeding.
• In case of even number of stations, the valve island is expandable up to 4 additional valve
stations.
• In case of odd number of stations, the valve island is expandable up to 3 additional valve
stations because the last sub-base is a single additional station.
• The maximum number of valve stations is 16 (32 solenoids).
Note:
• When changing number of valve stations of a valve island, the part number on the label will
no longer correspond to the configuration. If you order the valve island based on the Norgren part number, the original configuration will be delivered.
• If more than 4 additional valve stations are required to be added to the main PCB, the main
PCB must be changed.
• Fieldbus valve islands may have to be reconfigured after expansion. Please refer to the
specific information for each Fieldbus protocol in section
• For expansion of an AS-Interface valve island, please refer to section
• Please notice the position of blanking discs (multi pressure) before you expand a valve
island (see section
• Fieldbus valve islands contain electronic devices, which could be damaged through
