failed.
Bit 5 (0020)
(x_INMENU)
In menu. The MC menu system is engaged. This means that the effect of any
remote keycode requests are unpredictable.
Bit 6 (0040)
(x_STARVE)
Material starvation condition. The MC is in a state of low feedrate deviation
alarm. Only MCs that supports feedrate can have this bit set. It can be used to
take action on a feeder material starvation condition.
Bit 7 (0080)
(x_RECAL)
Recalibration. The MC has possibly been re-calibrated, since the rerate,
calibrate or service menu has been accessed. This bit is set until the MC has
been interrogated about scale factors and decimal point settings. When the
interrogation is completed, the bit is cleared.
Bit 8 (0100)
(x_INTSP)
Internal Setpoint. The MC is not in communications setpoint mode. Setpoint
values in SetPoint, F15:0,3,6.. (page 19) is ignored by the MC. This bit is never
set for MCs that do not support external setpoint, such as the 11.00.HP.
Instead, a “setpoint” setting us used for other purposes for these models. See
Setpoint (page 24) for details.
Bit 9 (0200)
(x_TAGERR)
Tag Access problem. A register, tagged for continuous reporting, is either non-
existent or read protected. Also, indication of difficulties downloading setpoints
to the controller.
Bit 10 (0400)
(x_INTSEC)
Internal Secondary Setpoint. The MC is not in communications setpoint mode
for the secondary setpoint. Secondary setpoint values in Secondary SetPoint,
F15:2,5,8..(x_SECPT) (page 19) is ignored by the MC. This bit is never set for
MCs that do not support external setpoint, such as the 11.00.HP. Instead, a
“setpoint” setting us used for other purposes for these models. See Setpoint
(page 24) for details.
Bit11 - 15 Reserved.
MC Internal State, N12:1,9,17..(x_INTSTA)
MCs with an internal state machine, such as 30.00.HP, 30.10.EX and 35.00.HP have an internal,
numeric integer variable, describing its operational state. The value of this variable is available in
this integer. For models that are continuous, such as 10.00.HP, 11.00.HP, 20.00.HP and 22.00,
this value is always 0. The interrogation of this variable is a part of the fast loop. To find out about
the internal state values, see Internal State, (page 27).
MC Digital I/O, N12:2,10,18..(x_DIGIO)
The states of the physical inputs and outputs of the MC are available in this integer. The
interrogation is a part of the fast loop. To find out about digital input and output designations, see
Digital I/O (page 25). The MC physical I/O is mapped to the following bits:
Bit 0 - 6 State of physical (relay) outputs 1..7 at backplane board #1. A "1" indicates a
closed relay output.
Bit 7 Reserved. The state of this bit is unpredictable.
Bit 8 - 11 State of physical inputs 1..4 at backplane board #1. A "1" indicates a closed input
circuit.
Bit 12 - 15 State of physical inputs 1..4 at backplane board #2. A "1" indicates a closed input
circuit.
Note that MC² controllers only have one backplane board.
