Monitoring the 1757-ABRIO Module Chapter 7
If you attempt to monitor a tag that has not been downloaded to the
1757-ABRIO module, AbRioCfg software displays a message that
indicates there is a configuration mismatch between the configuration
in AbRioCfg software and the configuration in the 1757-ABRIO
module.
Monitoring the Status of a
Block Transfer To monitor the current status of a block transfer, complete the
following steps.
1. Expand the chassis where the block transfer module you want
to monitor is located.
2. Select the module you want to monitor.
3. Right-click the module to highlight and select Monitor BT from
the menu.
The block transfer monitor displays the raw data for the block transfer
and some diagnostic information. For input modules there is both a
block transfer read and a block transfer write. The write consists of
configuration data.
The raw data can be displayed as hexadecimal, signed, or unsigned
integer. The default for block transfer data is hexadecimal.
Refer to the following table for diagnostic information on block
transfer reads.
TIP Use the same procedure to monitor digital and text data.
