• Assigning the valve supply

Assigning the valve supply
The S4, S5, and S6 switches for assigning the valve supply are located beneath PG fitting (B). The following is assigned to each switch:

• 4 double subbases for double solenoid valves (with solenoids 12 and 14) or
• 8 double subbases for single solenoid valves (with solenoid 14).

Fig. 11: S4, S5, S6 switches for assigning valve supply voltages (UQ1, UQ2)
This switch allows valves to be assigned in groups to valve supply voltages UQ1 and UQ2.
When delivered, all valves are assigned to the UQ1 voltage.
Table 12: Assignment of the S4, S5, and S6 switches

NOTICE

Voltage at switches
Switches can be damaged if voltage is applied to them during operation.

• Always operate switches in a voltage-free state!

How to assign the valve supply:
See g Fig. 11:

1. Open the lower screw cap (B).
2. Using the S4, S5, and S6 switches, assign each valve group to one of the two supply voltages UQ1 or UQ2. See also g Table 12.

Below you will find examples for the assignment of the S4, S5, and S6 switches and for supplying assembled valves. The following example combinations are listed there:

1. These examples only apply if there are no module extensions. You can also arrange other combinations based on your requirements.
2. From an electrical connection viewpoint, the double subbases for double solenoid valves must come first and then those for single solenoid valves.
3. The maximum number of solenoids for all subbases is 32.

2. Fields with numbers marked in bold indicate valve positions with single solenoid valves.

Configuring the bus coupler

The description in this section refers to the software BOOTP/DHCP Server, Version 2.3.2.0 of Rockwell Automation Inc. The software also contains online documentation which has to be observed during operation.
The configuration steps laid out in this section are superior to the settings on the bus coupler which have already been described and are a part of the entire system’s bus master configuration. See section g 7.1. Making presetting’s.

The work described here may only be carried out by qualified electronics personnel and in compliance with the operator’s documentation on configuring the bus master, as well as applicable technical standards, directives, and safety regulations.

Before starting configuration, the following steps must have been carried out and completed on the bus coupler:

• You have assembled the bus coupler and the valve terminal. See section g 6. Assembly.
• You have connected the bus coupler.
  See section g 6.3. Connecting the bus coupler electrically.
• You have carried out the presetting’s.
  See section g 7.1. Making presetting’s.

The configuration may also be carried out using other configuration software, but the described parameters and settings must be adhered to.

Configuring the bus system
EtherNet/IP™ stands for “Ethernet Industrial Protocol”. It is an open bus system that is based on the IEEE 802.3 standard and supports the widely used family of TCP/IP protocols. This is why it is also subject to specifications and limitations when assigning IP addresses (RFC: 791 INTERNET PROTOCOL; DARPA INTERNET PROGRAM PROTOCOL SPECIFICATION September 1981). To avoid the problems of a factory-set static IP address, the bus unit is set by default to address assignment using the DHCP protocol.
A dynamic or static IP address can then be assigned using the appropriate tool.

Before you start to configure the bus system, consult your network administrator on how to configure the network. Ask for the values for the subnet mask, gate-way, primary DNS, secondary DNS, and domain name.
To configure the bus system:

1. Start the BOOTP/DHCP server program.
   When the program is started for the first time, the network settings must be adjusted (steps 2 to 4).
2. In the menu bar, click “Tools” > “Network Settings”.
3. Enter the values for “subnet mask”, “gateway”, “primary DNS”, “secondary DNS” and “domain name”.
4. Click “OK”.

Fig. 12: BOOTP/DHCP server, network settings dialog
The bus coupler sends a DHCP query with its individual hardware address (MAC address). A line appears in the “Request History” window. Example: “13:57:39 DHCP 00:04:F3:00:1C:40”

1. Right click on this line.
2. Click “Add to Relation List”.
   The “New Entry” window opens.
3. Enter the IP address and confirm with “OK”.

Fig. 13: BOOTP/DHCP server, new entry dialog
The IP address is taken over in the relation list and transferred during the next query to the respective module. A line appears in the “Request History” window. Example: “14:00:32 DHCP 00:04:F3:00:1C:40 192.168.0.10”.

Fig. 14: BOOTP/DHCP server, relation list dialog

Saving the address list
You can save the list with “File” > “Save As” so you do not have to manually assign an IP address to each participant after every program start.
You can load the list with “File” > “Open“ after the next program start.

Change the IP address.
The specified IP address can be changed at any time:

1. Right click on the module in the relation list.
2. Click “Properties”.
3. Enter a new IP address and click “OK”.
   The new IP address will be taken over after the next power reset.

Fig. 15: BOOTP/DHCP server, properties dialog

Dynamic or static IP address
You can change the currently assigned IP address to a static IP address by clicking the “Disable BOOTP/DHCP” button. A BOOTP/DHCP server will no longer be needed for this device during the next system start.
If the module is entered in the relation list and highlighted with a right click, you can reactivate the automatic address assignment by clicking the “Enable DHCP” button.
