Channel 351 – Actuator Alarms (Index 111)
This channel, DI_ACTUATOR_ALARMS_CHAN, makes actuator alarms available to other function
blocks. The alarms include:
• Local emergency shutdown has occurred; the field unit will command the actuator to go to a pre-
configured position, or stop, or ignore the ESD.
• Remote emergency shutdown has been received from the network host; the field unit will
command the actuator to go to a pre-configured position, or stop, or ignore the ESD.
• Open inhibit is active.
• Close inhibit is active.

Channel 352 – Discrete User Input (Index 112)
This channel, DI_DISC_USER_INPUT_CHAN, makes general-purpose contact inputs available to other
function blocks. The functions in the table, such as ESD, must be configured to the OFF state locally
in the MX/QX PB setup menus in order to use the inputs as general-purpose inputs. Functions, such
as ESD, when configured to OFF, are not enabled. Refer to the following sections in MX Installation &
Operation Manual, LMENIM2306, and QX Installation & Operation Manual, LMENIM3306:
• Section 4.15 – ESD – Emergency Shutdown
• Section 4.16 – Inhibits – Open/Close Inhibit
• Section 4.13 – Remote Control – Open/Close/Stop Pushbutton Inputs
This channel places each discrete input bit value to 0 if the discrete input is not enabled.
