Publication 1769-UM002B-EN-P - July 2005
B-6 Module Addressing and Configuration with MicroLogix 1500
Configuring the Input Modules
For this example, the 1769-IF4 analog input module is installed in slot 1. To
configure the module, double-click on the module/slot.
Analog Input Configuration
Each of the four analog input words (channels) are enabled by default. To
enable a channel, click its Enable box so that a check mark appears in it. For
optimum module performance, disable any channel that is not hardwired to a
real input. Then, choose your Filter Frequency, Input Range, and Data Format
for each channel.
TIP
For maximum noise immunity, choose 50 Hz. For the
highest speed (fastest signal detection), choose 250 Hz.
