the device type, a field device can have an Input Publication panel. This
is determined by the DD file for the field device.
The Input Publication panel contains the following configuration options.
Contract Status — A contract is a communication resource
(bandwidth) allocation between two devices on the ISA100 network.
The following are the status values that are displayed depending on
the status of the contract.
• Not Configured - No contract established due to
incorrect configuration of the device.
• Activating - Contract establishment is in progress.
• Active- Contract is active.
• Active, Negotiated Down - If a device requests a
contract for periodic publications at a fast rate (such as 1
second) and if the communication resources are not
available, the contract is negotiated down to a slower
publication period (such as 5 seconds).
• Terminating - Contract termination is in progress.
• Failed - Contract establishment is failed.
• Inactive - Contract is inactive.
Rate – The rate at which a field device publishes data.
NOTE:
Honeywell recommends that you set the Rate as 10
seconds.
Stale Limit – Defines the maximum number of stale input values that
can be received before the input status is set to Bad. It is recom-
mended that for 1 second publication period, the stale limit should be
set to 15 seconds. For all other publication periods (5 seconds, 10
seconds, 30 seconds, and 1 minute), the stale limit should be set to 5
Destination – Destination of publication for output devices .
Channel – The list of channels for which the publication configuration
applies.
NOTE:
When a device joins the network, the WDM automatically
configures its publication period as 30 seconds.
