Chapter 8 Use I/O Modules with CompactLogix 5370 L2 Controllers
Remove and Replace the Connector
Complete these steps to remove and replace an embedded I/O module
connector.
1. Verify that the control system is not powered.
2. Compress the small release clips at the top and bottom of the connector
and tilt the top of the connector away from the module.
3. Pull the connector away from the module and disconnect any wires.
4. Connect the wires to the replacement connector.
5. Push the connector back into the module and engage the clips to secure
the connector.
Determine Embedded
Module Update Time
The module update time is the time that the module requires to sample and
convert the input signals of all enabled analog input channels and provide the
resulting data values to the controller.
You calculate the module update time by adding the update times for each
enabled analog input channel on the module. Each channel update time
calculation is the result of several configuration choices that are described in
the following section.
IMPORTANT This section applies to the 1769-L24ER-QBFC1B and 1769-L27ERM-QBFC1B
controllers because only those controllers have embedded universal analog
input points.
