WARNING
Do not remove the 1797-CEC or 1797-BIC modules under power.
Removing these modules under power will break the electrical
backplane (flexbus) connections. This can cause personal injury or
property damage by:
 sending an erroneous signal to your system’s field devices
causing unintended machine motion.
 causing an explosion in a hazardous environment.
 breaking communication to modules beyond this module.
