MX/QX FOUNDATION Fieldbus Field Unit FCD LMENIM2330-01 – 08/11

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.

Local ESD Active 0x01

Remote ESD Active 0x02

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.
