13-26 SLC Communication Channels
Table 13.8 Define these communication parameters when configuring an SLC 5/05 processor for Ethernet communications.
Tab Parameter Default Selections
General Diagnostic File 0 Select an unused file to store channel status information. You must define a diagnostic file
in order to be able to view channel 1 status. The Diagnostic File Number must be an
integer within the limits of 9 to 255. See Table 13.10 for a file description.
Hardware
Address
Ethernet
hardware
address
The SLC 5/05 Ethernet hardware address.
IP Address 0, 0, 0, 0
(undefined)
The SLC 5/05 internet address (in network byte order). The internet address must be
specified to connect to the TCP/IP network.
Subnet Mask 0, 0, 0, 0 The SLC 5/05 subnet mask (in network byte order). The Subnet Mask is used to interpret IP
addresses when the internet is divided into subnets. A Subnet Mask of all zeros indicates
that no subnet mask has been configured.
Gateway
Address
0, 0, 0, 0 The address of a gateway (in network byte order) that provides connection to another IP
network. A Gateway Address of all zeros indicates that no gateway has been configured.
Default Domain
Name
This is the portion of the Domain Name that is the same for every device on the local
Ethernet network. When a target device name is entered in the Ethernet MSG instruction
in place of the target device IP address, then the Default Domain Name is appended to the
device name when the MSG is triggered and a request is made for the corresponding IP
address from the DNS server. The default domain name can have the following formats:
’a.b.c’, ’a.b’ or ’a’, where a, b, c must start with a letter, end with a letter or digit, and have
as interior characters only letters, digits or hyphens. Maximum length is 47 characters.
Primary Name
Server
(1)
0.0.0.0 This is the IP address of the computer acting as the local Ethernet network Primary Domain
Name System (DNS) server.
Secondary
Name Server
(1)
0.0.0.0 This is the IP address of the computer acting as the local Ethernet network Secondary
Domain Name System (DNS) server.
DHRIO Link ID 0 The link ID assigned to this SLC 5/05 in a 1756-DHRIO module routing table so that DH+
devices can initiate communications to this SLC 5/05.
Pass Thru
Routing Table
File
0 Enter an integer file from 9 to 255. This file (routing table) stores up to 128 IP addresses
that may be accessed by devices connected to channel 0 using either DF1 Full-duplex, DF1
Master, DF1 Radio Modem, or DH-485 protocols.
User Provided
Web Pages
Starting Data
File Number
(2)
0 (disabled) Enter the first in an unused block of data table file numbers within range of 9 to 252. This is
the starting data table file number used to store user-provided web pages. Each page is
stored in a block of four consecutive 256-element ASCII files.
User Provided
Web Pages
Number of
Pages
(2)
1 Enter 1 to 16. This is the total number of user-provided web pages. Each web page
allocates four contiguous 256 element ASCII files. All web pages reside in a contiguous
block of ASCII files from four to 64 files in length.
Channel 1
System
MSG
Connection
Timeout
15,000 ms The amount of time (in ms) allowed for a MSG instruction to establish a connection with
the destination node. The MSG Connection Timeout has a range from 250 ms to 65,500 ms.
MSG Reply
Timeout
3,000 ms The amount of time (in ms) that the SLC 5/05 waits for a reply to a command that it has
initiated via a MSG instruction. The MSG Reply Timeout has a range from 250 ms to 65,500
ms. This timeout also applies to Ethernet-to-channel 0 passthru commands.
