Sigma DNN Configuration for Subnetted Ethernet Networks

[Product_Support]

Issue

Guidance on configuring a Sigma Distributed Network Node (DNN) when connecting to a subnetted Ethernet network.

Product Line

Satchwell BAS & Sigma

Environment

• Satchwell Sigma
• Subnetted Ethernet network

Cause

A subnetted Ethernet network consists of multiple subnets. For example:

• Network: 10.158.1.0
• Subnet Mask: 255.255.255.0
• Valid IP range: 10.158.1.1 to 10.158.1.254
• Another subnet might be: 10.158.2.0

In such environments, the Sigma DNN must be configured with:

• A valid IP address
• A Subnet Mask
• A Static Route

Resolution

1. Assign IP Configuration

   • Set the DNN’s IP address and subnet mask according to the subnet it resides in.

2. Configure Static Route

   • Use the Pocket Terminal 32 program.
   • Syntax:

     SR+ 0.0.0.0/0 <Default Gateway IP> <Ethernet Port Number>
     

   • Example:
     If the default gateway is 10.158.1.254 and the Ethernet port is 5, enter:

     SR+ 0.0.0.0/0 10.158.1.254 5
     

3. Disable RIP (Routing Information Protocol)

   • RIP is enabled by default and may interfere with static routing.
   • To disable RIP on port 5:
     • Open Pocket Terminal
     • Enter:

       RIPD 5
       

     • Click Send

4. Inform IT Network Administrators

   • Since RIP is disabled, sublan routes are not broadcast.
   • Ensure that manual routing entries are added to network routers.

Additional Notes

• This configuration ensures reliable communication between Sigma controllers and the DNN across subnet boundaries.
• Always verify routing with IT before deployment.
