Adjusting the TV-PSM driver properties
Communication Status
The Communication Status page shows the status of the protocols currently running on the TV-PSM's ports.
Standalone Controller Detection
You can use the fields on this page with a binary input in your control program to detect when the controller does
not receive a write request from the selected network within the specified amount of time. The input remains OFF
as long as write requests are received, but switches to ON if the controller does not receive a request within the
specified time. The binary input must have the Expander number and Input number set to 99 and the I/O Type set
to Special.
Modbus Serial, Modbus TCP/IP, and Modbus Error Definitions pages
If the controller will be used with Modbus devices, see the Modbus Integration Guide for information on using
these pages.
To set up Network Statistic trends
PREREQUISITE To view Network Statistic trends, you must have a i-Vu® v6.5 or later system with the latest
cumulative patch.
To view the Network Statistics (page 35) as trend graphs, select the controller in i-Vu®'s navigation tree and go to
one of the following:
•
On the Driver Properties > Network Diagnostics > Statistics page, click a Trend link at the bottom of each
section.
•
Click the Trends drop-down button, select Enabled Points and then the graph you want.
You can define:
•
How the graph looks on the trend's Configure tab.
•
How you want trend samples to be collected on the Enable/Disable tab. See table below.

Notes
(Recommended method) To record the value at a regular time interval, enter
hh:mm:ss in this field.
To record the value only when the value changes by at least the amount of
the COV Increment, set the Sample every field to 0:00:00 and enter a value
in the COV Increment field.
Network Statistic trends have a non-configurable maximum trend log buffer
size of 1440.
NOTE Trending consumes memory in the controller. Click Reset to delete all
samples currently stored in the controller.
