Channel 6 – Actuator Alarms
The Channel 6 Discrete Input function block, DI_ACTUATOR_ALARMS_CHAN, makes actuator alarms
available to other function blocks. The alarms include:
• Local emergency shut down has occurred; the field unit will command the actuator to go to a
preconfigured position, or stop, or ignore the ESD.
• Remote emergency shut down has been received from the network host; the field unit will
command the actuator to go to a preconfigured position, or stop, or ignore the ESD.
• Open inhibit is active.
• Close inhibit is active.
Channel 6 DI_ACTUATOR_ALARMS_CHAN Value

Open Inhibit Active 0x04
Close Inhibit Active 0x08
Local ESD Active + Open Inhibit 0x05
Local ESD Active + Close Inhibit 0x09
Remote ESD Active + Open Inhibit 0x06
Remote ESD Active + Close Inhibit 0x0A
Open Inhibit Active + Close Inhibit Active 0x0C
Channel 7 - Discrete User Input
The Channel 7 Discrete Input function block, 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 FF 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 Installation and Operation Manual Bulletins LMENIM2306 for the MX and
LMENIM3306 for the QX:
• Section 4.17 – ESD - Emergency Shutdown
• Section 4.17.2 – Inhibits - Open/Close Inhibit
• Section 4.13 – Remote Control - Open/Close/Stop Pushbutton Inputs This channel places each
discrete input to 0 if the discrete input is not enabled.
