Hello everyone,
I have recently purchased a 1762sc-IF8u module for a Micrologix 1400 plc.
I have spent the entire day trying to get the unit to read proper inputs and have failed so far, I figured I would join this website to get some possible solutions.
I currently have two inputs that I am trying to read with the module.
1. RTD (3 wire w/o comp), 100 Pt 385
2. 4-20mA Vacuum Sensor (Range 0-5mmHg)
I have written the following bit settings to the respective output words:
RTD = 0100010001000100
VAC = 0001000000000000
All the dip switches are in the "current" position according to the manual picture.
When I wire up the RTD I get a value of -541. When I wire up the 4-20mA signal I get a full signal (when it shouldn't be, cross checked).
Is there something I am missing regarding the configuration of this module?
