1. About this documentation
This Operation & Service Manual contains the information to set up and operate the VS18/VS26
valve islands with EtherNet/IP interface and to detect and resolve problems.
Note:
In addition to the specific information for the EtherNet/IP variants, all data sheets for the
VS18/VS26 valve island series are applicable and remain valid. The difference between the both
variants consists of the sizes of valves and the resulting maximum flow rate. All electrical
connections and parameterization are the same for both variants.
Refer also to the datasheets on the following weblinks:
http://cdn.norgren.com/pdf/en_5_1_250_VS18.pdf

2. Important hints
2.1 Grounding and equipotential bonding
Proper grounding and equipotential bonding are very important to protect against electromagnetic
interferences in Ethernet networks. In order to reduce potential impact, grounding of the Ethernet
cable screen should be done at both ends of every cable (i.e. at each device). Equipotential
bonding ensures that the ground potential is identical throughout the entire Ethernet network and is
essential to avoid equipotential bonding currents, which could otherwise flow through the Ethernet
cable screen.
Ground connection needs to be established using the M4 thread on the rear of the connection
module. Its location shows the red arrow on the following picture.
2.2 Intermediate supply/exhaust module (ISEM)
In cases where the channel diagnostics is activated on the valve island, the channel diagnostics
setting should be disabled at the position of each ISEM. This needs to be done in order to avoid
any misleading failure indication due to missing electronic components in the ISEM.
2.3 ATEX Note
Please refer to the corresponding ATEX installation instructions and the maximum permissible
operating conditions for valve islands in an ATEX zone.
The maximum allowed power consumption is 20W. This corresponds to 16 simultaneously
energized pilot valves. If a configuration consists of more than 16 pilot valves the user must
undertake external actions (e.g. power-limited power supplies) to make sure that the power
consumption of 20W is not exceeded.
For further details, please refer to the corresponding ATEX installation instructions or contact your
Technical Support.

2.4 Power-up and initialization phase of the VS18/VS26 valve island
It is possible to read the actual installed firmware release using the Logix-Designer from Allen-
Bradley. Please refer to chapter 4.4 for more details.
2.4.1 Firmware release V1.001 and lower
The valve island initializes automatically after power-up. During initialization the number of
available valve stations is also evaluated, which requires that at this point also the power supply for
the valves (VA) is already available during initialization start. Otherwise not all valve stations might
be detected and initialization of the valve island fails. This failure case is indicated by the following
permanent Status LED states:
P1 –off
P2 –off
NS –off
MS –red
VB –green
VA –green
2.4.2 Firmware release V1.002 and higher
The requirement as described in chapter 2.4.1 is not applicable for the firmware release V1.002
and higher.
The initialization of the valve island is performed during the testing in production before delivery.
Note:
In case any changes are made on the hardware of the valve islands (i.e. adding or removing valve
stations), the power supply must be completely disconnected by unplugging the power supply
connector.
After the hardware change is completed, the new configuration must be initialized.
During initialization the number of available valve stations is evaluated, it is therefore required to
have both the power supply for electronics (VB) and power supply for the valves (VA) available.
Furthermore it is required to adjust the valve island size in the PLC / Hardware configuration for
proper functioning and diagnosis.

4. Commisioning
The configuration of the EtherNet/IP valve island is done via inclusion of the device description file
(EDS file) „002A002Bxxxx0100.EDS“. The device description file is required to be included for the
configuration of the corresponding EtherNet/IP - Controller.
Note:
xxxx = ‘2000’ -> VS18/26 with 4 Stations
`2100` -> VS18/26 with 6 –8 Stations
`2200` -> VS18/26 with 10 –12 Stations
`2300` -> VS18/26 with 14 –16 Stations
`2400` -> VS18/26 with 18 –20 Stations
Note: All explanations in this manual are based on Rockwell Automations “Studio 5000”.
The following steps are necessary.
4.1 EDS File Installation
The EDS file is required to configure the VS18/VS26 valve island. A symbol file is necessary to
display an icon in the engineering tool.
EDS files are provided by the module vendor and can be downloaded from:
https://www.imi-precision.com/uk/en/technical-support/software
Note: The method of module installation strongly depends on the configuration software. Please refer to
the configuration software manual.
The following picture shows Startup image of Rockwell Automations “Logix Designer”.

In menu “Tool -> EDS Hardware Installation Tool” start the Installation Wizard. Follow the
installation steps described in the wizard.
After the installation the new module is shown in the catalogue.
4.2 Hardware configuration: Select valve island
After the successful installation of the EDS file, the module configuration is needed. In context
menu choose “New Module” after right-clicking on “Ethernet”.

In dialogue tab “Connection” change “Requested Packet Interval (RPI)” greater than or equal to 10
ms and click “OK”. The RPI times has a direct impact to the busload.
Note: The lower the cycle times, the higher the busload.
The picture bellow shows module tree with the new added module.
After successful configuration please perform download by clicking „Download“ in the menu item

4.3 Set up IP Address
4.3.1 Using a DHCP Server
As default the VS18/VS26 valve island is set up as a DHCP client. In this mode IP Address has to
be assigned using a DHCP server or a similar tool. This has to be repeated after each power cycle.
The following example shows the IP Address assignment using Rockwell Automations
BOOTP_DHCP Tool.
It is important to ensure that the network adapter set up in the “Network Settings” of the tool is the
one, which is connected physically to the VS18/VS26 valve island.
Menu: “Tools” -> “Network Settings”
The VS18/VS26 valve island should then appear in the “Discovery History” list. Double clicking the
MAC Address opens the dialog used to set up the IP Address.
The IP Address settings are transferred into the “Discovery History” if they are valid and confirmed
with the “OK” button. Pushing the “Enable BOOTP/DHCP” Button enables the IP Address
assignment for the chosen entry. The VS18/VS26 valve island will appear with assigned IP
Address in “Discovery History” list if address assignment was successful.
4.3.2 Static IP Address assignment using TCP/IP Interface Object
Configuration method of the IP Address could also to be set up as a static value. The interface
configuration is saved to NV storage. This has to be done once and is valid after a power cycle.
The Read/Write access to the TCP/IP Interface Object is done via the Explicit Messages
communication method.
The configuration method is set up with the bits0-3 in attribute 3. Please use the statically-assigned
IP configuration set up value “0” for those bits.

4.4 Firmware version and serial number
It is possible to read the actual installed firmware version and serial number of the device using the
Logix-Designer (Allen-Bradley). This information is accessible via the Identity Object (Attribute 3)
as described in this section.
Connect to the PLC by choosing the “Go Online” option in the “Communications” drop-down menu.
As soon as the connection with the PLC is established, select the corresponding Valve Island from
the list of Ethernet modules and open the module “Properties”in the context menu or by double-
click.
