Chapter 6 Add and Configure Standard I/O Modules
• When possible, use specialty Compact I/O modules to meet unique
application requirements.
• Consider using a 1492 wiring system for each I/O module as an
alternative to the terminal block that comes with the module.
• Use 1492 PanelConnect™ modules and cables if you are connecting
input modules to sensors.
Install Local Expansion Modules
Complete these steps to install local expansion modules in your Compact
GuardLogix 5370 controller system.
1. Attach the 1769 Compact communication or I/O modules as described
in these publications:
• Compact I/O Modules Installation Instructions, publication
1769-IN088
• Compact I/O DeviceNet Scanner Module Installation Instructions,
publication 1769-IN060
2. If your system uses only a local bank, complete these steps.
a. Use the tongue-and-groove slots to attach a 1769-ECR Compact
I/O end cap terminator to the last module in the system.
b. Move the lever of the end cap bus terminator fully to the left until it
clicks to lock the end cap bus terminator.
3. If your system uses more banks, follow these steps.
a. Install a 1769-CRx Compact I/O communication bus expansion
cable at the right end of the local bank.
b. Connect the 1769-CRx cable to the additional bank as necessary.
That is, how you connect to the first extra bank—on the right or left
side of the bank, determines the expansion cable that is installed at
the end of the local bank. See page 93
for an example of how to
connect a local bank to extra banks.
c. Complete the installation of the remaining banks in your system.
Figure 2 on page 28
shows example systems with local expansion modules
included.
Wire Local Expansion Modules
Wire each Compact I/O module that is used as a local expansion module
according to the technical documentation for that module.
IMPORTANT Make sure that you install an end cap at the end of the last bank
in your system.
