1 Ethernet, IP Addresses and Honeywell Automation Systems

2 2HONEYWELL - CONFIDENTIAL File Number Background – Ethernet Connections Cat-5 Though Ethernet now supports many media, the most common one in use is Cat 5 (Category-5) twisted-pair cable. Maximum distance between nodes is restricted to 100 meters. The maximum distance between any two nodes on a segment cannot exceed 2500 meters The maximum number of nodes on a network is 1024, but actual experience has shown that when the number of nodes on a network exceeds 200, too much of the networks bandwidth is wasted by collisions.

3 3HONEYWELL - CONFIDENTIAL File Number Background: Ethernet Connections PC-to PC Connections using Ethernet require a crossover cable Or Electrically powered switch/hub/router

4 4HONEYWELL - CONFIDENTIAL File Number Background – TCP/IP addressing Most PCs, Laptops and most modern automation systems include at least one component with an Ethernet connection. All Ethernet ports have a unique addressed called the MAC address, but it is typically not used Common network communication relies on TCP/IP addressing. (Transmission Control Protocol / Internet Protocol)

5 5HONEYWELL - CONFIDENTIAL File Number Background - (TCP)/IP Address IP addresses are typically expressed as 4 groups of numbers separated by a. Each group is between 0 and 255 Each decimal number represents an 8-bit binary group Example:

6 6HONEYWELL - CONFIDENTIAL File Number IP Subnet Mask Each IP Address includes a subnet mask Subnet filters RESTRICT Ethernet connections Subnet numbers act as a MASK or Gate Each subnet segment is a string of leading 1s and 0s Each subnet segment may only equal one of 8 numbers: 255 = (must match exactly) 254 = (must match except last bit (2 allowed)) 252 = (must match except last 2 bits (4 allowed)) 248 = (must match except last 3 bits (8 allowed)) 240 = (must match except last 4 bits (16 allowed)) 224 = (must match except last 5 bits (32 allowed)) 192 = (must match except last 6 bits (64 allowed)) 128 = (must match except last 7 bits(128 allowed) 0 = (passes through everything! (256 allowed))

7 7HONEYWELL - CONFIDENTIAL File Number Subnet Mask Filtering Example 1: (IP) (255 blocks everything that does NOT match) Thats equal to: (IP) (SUBNET) Only allows IP addresses : up to any So this computer may connect to any other with an IP address from up to

8 8HONEYWELL - CONFIDENTIAL File Number Subnet Mask Filtering Example 2: (IP) (block all but 8 computer addresses) Thats equal to: (IP) (SUBNET) Only allows: up to only This computer will only connect with IP addresses from up to

9 9HONEYWELL - CONFIDENTIAL File Number Connecting a Server to the Internet Server is part of a LAN LAN has a switch/hub LAN has a router/gateway for connection to the Internet Account has fixed single IP address Router uses MAP function Fixed Server IP address MAP setup DSL Router, Gateway & DNS Address Fixed EXPOSED Internet IP

10 10HONEYWELL - CONFIDENTIAL File Number Assigning Addresses – Static and Dynamic How are IP address assigned to the node? There are two basic methods; manual and automatic Automatic IP address are generated from a DHCP server or router somewhere else on the network When an IP address is assigned manually, it is referred to as a static IP address. Each time the node is connected to the network, it will use the IP address that was assigned. Windows users assign static IP addresses - Start - Settings - network connections

11 11HONEYWELL - CONFIDENTIAL File Number Changing a Static IP Address with Windows 1. Open Network Connections 2. Open Local Area Connection 3. Select Properties 4. Select Internet Protocol (TCP/IP) 5. Select Use the following IP address

12 12HONEYWELL - CONFIDENTIAL File Number Direct Connections with Static IP addresses 1.Manually Set IP Address on PC similar to controllers IP address (within allowed subnet range)

13 13HONEYWELL - CONFIDENTIAL File Number Identifying an IP address on a PC: Start > Settings > Network Connections Select Local Area Connection View the Support Tab (assigned by DHCP In this example)

14 14HONEYWELL - CONFIDENTIAL File Number Identifying IP address on JACE See installation Instructions - Remove Cover - Set Mode Jumper for Serial Shell - Use Serial NULL modem cable on COM-1 - Use HyperTerminal software for connection 115,200 8-N-1 - On boot up will display Ethernet port address

15 15HONEYWELL - CONFIDENTIAL File Number Identifying IP address on WEBs 400/500 See installation Instructions - Set Mode Jumper for Serial Shell - Use Tridium adapter cable for COM-1 - Use HyperTerminal software for connection 57,600 8-N-1 - On boot up will display Ethernet port address

16 16HONEYWELL - CONFIDENTIAL File Number PINGing a computer Utility program built into windows Verifies proper Ethernet IP to Ethernet IP communication Select Start > Run > type command to open window In the command window type ping xxx.xxx.xxx.xxx where xxx is the IP address to verify communication to Type exit to close command box
