B-4 Troubleshooting and Common Questions
Transmission Problems
If a device does not transmit alarms or trends, you have not
configured them yet. For instructions on how to configure alarms and
trends, refer to the Configuring Alarms and Configuring Trends
sections on pages 4-25 and 4-26, respectively.
If a device does not publish the data you configured it to transmit,
complete these steps:
1. Edit the schedule to add more time to the communication
schedule. To edit the schedule, double-click the Schedule icon
in the Project window.
For more information about editing the schedule, refer to the
Viewing and Editing a Schedule section on page 4-27.
2. If your project reads and polls information continuously, turn off
polling to see if the device publishes the data. To turn off
polling, uncheck the Periodic Updates checkbox at the top of
the Block window.
Mode Transition
If a function block alternates between IMAN and AUTO modes, your
function block and communication schedules do not have enough
time between them. To solve this problem, complete these steps:
1. Edit the schedule to add more time between the function block
and communication schedules.
For information about editing the schedule, refer to the Viewing
and Editing a Schedule section on page 4-27.
2. After you edit the schedule, select Configure ⇒ Download
Configuration to download the changes.
For information about downloading the configuration, refer to
the Downloading a Configuration section on page 4-31.
