The following two tables show the LED behaviors of CHARM Scanner Modules installed on CHARM I/O Gateways and CHARM I/O Blocks.
Animated illustrations of the LED behaviors are available only in HTML help files, and only on non-DeltaV machines and DeltaV machines that are part of a workgroup. If you are viewing this topic in PDF form, or on a DeltaV machine that is part of a domain, the LED Behavior columns in the following tables display only static images of the LEDs.
