FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can 1766-L32BXB replace an AC-powered MicroLogix 1400 without rewiring?
No. 1766-L32BXB requires 24 VDC input power and has a mixed relay/FET output arrangement. Verify supply, output commons, field voltages, project configuration and load types.
Can a 1766-L32BXBA project be loaded unchanged into 1766-L32BXB?
Not when it uses the BXBA's embedded analog channels. Remove or remap analog references and verify the exact controller selection, I/O image and wiring before download.
Can every transistor output on 1766-L32BXB run high-speed PTO or PWM functions?
No. The official specification assigns enhanced high-speed operation to outputs 2, 3 and 4, and their tighter current limits must be respected.
Why might EtherNet/IP devices not reconnect after replacing 1766-L32BXB?
Check the stored IP method and address, subnet and gateway, switch port, duplicate IP, channel configuration, message paths, device ownership and controller firmware/project compatibility.
What information should be backed up before servicing 1766-L32BXB?
Save the online project and data, passwords, channel settings, IP configuration, serial protocols, high-speed counter and PTO/PWM setup, expansion-I/O map and diagnostic history.
How should expansion I/O be checked for 1766-L32BXB?
Confirm no more than seven supported 1762 modules, calculate both expansion-bus rail currents for the installed Series, and verify cable seating and the downloaded module order.
How should 1766-L32BXB be commissioned after installation?
Verify 24 VDC power and all commons, restore the approved project and communications, exercise every used input and output, test high-speed functions and expansion I/O, then prove alarms and the controlled sequence.
