The digital input status is displayed in measures
M031
,
M032
,
M033
,
M034
,
M035
.
Measure
M033
shows the
current
status of the 8 inputs in the local hardware terminals in the drive board. The
input called
MDI2&S
(“
S
” on the display keypad) is active only if both physical inputs
ENABLE-A
and
ENABLE-
B
are active.
The symbol displays the logic levels for terminals
M033
for inactive inputs; the active inputs are marked with
.
Measures
M034
and
M035
show the tatus of the terminal boards that can be activated via serial link and fieldbus
respectively.
Measure
M032
shows the
current
status of the virtual terminal board obtained by processing all active terminal
boards. It includes 10 signals, with two additional signals with respect to the local hardware terminal board:
•
Inputs
MDI1
to
MDI8
are obtained with the
logic
OR
of the input signals for all active terminals;
•
The
ENABLE
function is obtained with the logic
AND
of the input signals for terminal
MDI2&S
(physical terminal
board) and terminals
MDI2
(serial link and fieldbus) in all active terminal boards, unless parameter
C154a
is active.
•
The
ENABLE–SW
function is obtained with the logic
AND
of the terminals selected for this function in all
active terminal boards.
Measure
M031
is similar to
M032
, but it displays the status of the terminal board obtained after delaying the input
signals of M032 using special timers.
The drive uses this terminal board to acquire digital commands.
Some functions cannot be programmed, but they are assigned to special terminals:

Some terminals in the local hardware terminal board can also be used for different functions:
