AN-X4-ABRIO-SCAN
Nov 2023
In semi-automatic mode, the module configuration data values come from ControlLogix scheduled
output data mapped to the block transfer. The size of the configuration block transfer write is the data
BTW length, BtwLen, plus the Config BTW Length, CfgLen, from the template, and this is the length
mapped to ControlLogix scheduled output data. The data block transfer write length is BtwLen from
the template.
The size of the data block transfer read is set by the configuration tool.
If you are using a semi-automatic block transfer, ensure that the configuration data is set in the
ControlLogix data table before the program starts.
Manual
To execute block transfers in manual mode:
•
Fill in the BTR and/or BTW length and BTW data in the control block for the module
•
Set the BTR.EN and/or BTW.EN bits (and BTR.CONT/BTW.CONT for continuous
execution)
•
Check the BTR.DN/BTW.DN bits that indicate BT execution is complete (BTR data is
available at that time)
•
Check the BTR.ERR/BTW.ERR bits. If set, read the error code to determine the cause of the
problem.
Inhibiting Automatic Block Transfers
To inhibit a running automatic or semiautomatic block transfer, set bit 9 in offset 0 of the mapped
block transfer output data for the module. Setting the bit inhibits both the block transfer read and the
block transfer write to the module.
Monitoring operation
Discrete Inputs and Outputs
To monitor discrete inputs, do one of the following:
•
from the main menu, select
Monitor/Discrete Inputs
•
right click on a rack and select
Monitor Discrete Inputs
•
use the
Monitor Discrete Inputs
button on the toolbar
The Discrete Input monitor window appears.
