You must configure Channels in the SCADAConnect Forms or DMS [https://rubiconwater.atlassian.net/wiki/spaces/SMNC/pages/2000979029](https://rubiconwater.atlassian.net/wiki/spaces/SMNC/pages/2000979029) before you can use the [Channel View](https://rubiconwater.atlassian.net/wiki/spaces/NC/pages/2298576937/Site+List+and+Map+Views#Channel-View) and before you can filter the *Unscheduled Orders* list in a plan by the channel headgate.

# How are Channels Configured?

Channels are configured using the CHANNEL MEMBERSHIP relation. The Headate at the top of the channel is the channel parent and the downstream sites are members of its channel. To set up a new channel:

- In the DMS or SCADAConnect Forms [https://rubiconwater.atlassian.net/wiki/spaces/SMNC/pages/2000979029](https://rubiconwater.atlassian.net/wiki/spaces/SMNC/pages/2000979029) select the site that will be the channel headgate.
- (Optional) Give the channel a name by setting the **Channel Name** attribute for the headgate.

> ℹ️ **Note**
> ℹ️ 
> ℹ️ - Only the headgate site needs to have the Channel Name set.
> ℹ️ - If you don’t provide a channel name the channel will have the same name as the headgate.

- Create CHANNEL MEMBERSHIP relations between the headgate site and the member sites in the channel.

> ℹ️ **Note**
> ℹ️ 
> ℹ️ You can set up relations in the Objects module by selecting either the headgate site or by selecting a member site. 
> ℹ️ 
> ℹ️ - If you have selected the headgate site, then choose *Super Object* in the **Inserting Relations** screen and enter the channel member name in the **Sub Object** field.
> ℹ️ - If you have selected a member site, then choose *Sub Object* in the **Inserting Relations** screen and enter the channel headgate name in the **Super Object** field.
> ℹ️ 
> ℹ️ The sequence number always applies to the sub object.

See the following examples for more details.

# Example of a Channel Configuration 

Suppose we have three channels as shown in the diagram below. We will do the following:

- [Create a new channel ](https://rubiconwater.atlassian.net/wiki/spaces/NC/pages/2299756611/Configuring+Channels+for+Channel+View#Example%3A-Create-a-New-Channel)for Regulator D6 called *LAT D* and add Outlet E1 as a channel member.
- [Add a new site](https://rubiconwater.atlassian.net/wiki/spaces/NC/pages/2299756611/Configuring+Channels+for+Channel+View#Example%3A-Add-a-New-Site-to-the-Channel) E2 to the end of channel LAT D

Sites can be added to the channels by creating a CHANNEL MEMBERSHIP relation with the channel headgate. For example, if we look at the site LATERAL A in the DMS **Objects module > Relations tab** we can see all of its CHANNEL MEMBERSHIP relations. 

- LATERAL A has a relation with LATERAL 1 (item 2 in the image below) because it belongs to the channel LAT 1
- LATERAL A has relations with sites D1, D3, D4, D5, and D6 (item 3 in the image below) because they belong to its channel LAT A

If we look at the **LAT A** channel in NetworkConnect we can see the sites listed in the order specified in DMS using the *Sequence Number*.

> ℹ️ **Note**
> ℹ️ 
> ℹ️ The sequence numbers can start at any number and don’t have to be contiguous. For example, in this list site D1 has a sequence number of 3 but is the 4th site in the channel (because the sequence numbers happen to start at 0 in this example).

# Example: Create a New Channel

Suppose we want to create a new channel with Regulator **D6** as the headgate and add outlet **E1** as a channel member.

**Step 1**

Select the regulator **D6** in the **Objects** module and open the **Attributes** tab.

> ℹ️ **Note**
> ℹ️ 
> ℹ️ Make sure that you have selected the Regulator object (in this case a FlumeGate R) and not the Screen object

**Step 2 **

Select the **Channel Name** attribute and click the **Modify** button. We will set the Channel Name to *LAT D*.

**Step 3**

Now open the Relations tab. 

- D6 will already have a CHANNEL MEMBERSHIP relation with LATERAL A because it is a member of the LAT A channel.
- We must create a new CHANNEL MEMBERSHIP relation between D6 and a site in the channel like E1 to create our new channel LAT D.

Click **Insert** to add a new relation for D6.

- Set the radio button to **Super Object**. This specifies the role of the selected object (D6) which will be the headgate for channel LAT D.
- Set the **Relation Type** to *CHANNEL MEMBERSHIP*
- Set the **Sub Object** to *E1* to add it as a member of the new channel.
- Set the sequence number to control the position of the member site (E1) in the channel in NetworkConnect and SiteConnect (in this case we’ll set it to 10 in case we later want to add some sites upstream of E1).

# Example: Add a New Site to the Channel

We will add a new site E2 to channel LAT D downstream of site E1 that we added when we created the channel.

**Step 1**  
Select the new site E2 in the **Objects** module and open the **Relations** tab.

**Step 2**

Click **Insert** to add a new relation for that site.

- Set the radio button to **Sub Object.** This sets the role of the selected object E2 which will be a channel member in channel LAT D
- Set the **Relation Type** to *CHANNEL MEMBERSHIP*
- Set the **Super Object** to *D6* (the headgate for channel LAT D).
- Set the sequence number to control the position of the member site in the channel in NetworkConnect and SiteConnect (in this case we’ll set it to 20 so that it appears after of E1 and we have some spare positions if we need to later add sites between E1 and E2).

**Step 3**

Click **Save **to save your new channel member. Site **E2** will now appear as the second site in channel **LAT D** because we have given it a higher sequence number than E1. 

If we now look at the channel LAT D in NetworkConnect or SiteConnect Channel view it will have two members - E1 and then E2.
