Object description and parameterization
EM7004 97 Version: 2.0
5.1 Objects for commissioning
Index 80n0 AO Settings Ch.1 - 4 (for 2 ≤ n ≤ 5)
Index (hex) Name Meaning Data type Flags Default
80n0:0 AO Settings Ch.1 - 4 Maximum subindex UINT8 RO 0x13 (19
dec
)
80n0:01 Enable user scale FALSE
The user scaling is deactivated
TRUE
The user scaling (object 0x80n0:11, 0x80n0:12) is active;
the output value is then calculated as described in the
Calculation example [
}
14] .
BOOLEAN RW 0x00 (0
dec
)
80n0:02 Presentation 0:
Signed Presentation:
The output value is output as signed integer in the two's
complement
0x7FFF = +10 Volt
0x8001 = -10 Volt
1:
Unsigned Presentation:
In the negative range, the value is output as an absolute
value
0x7FFF = 10 Volt
0x8001 = 10 Volt
2:
Enable absolute value with MSB as sign:
The output value is displayed in magnitude-sign format
0x7FFF = +10 Volt
0xFFFF = -10 Volt
BIT3 RW 0x00 (0
dec
)
80n0:05 Disable watchdog FALSE
The watchdog is active. In the event of a failure of com-
munication, the analog output value will be set to either
the manufacturer's or the user's default value.
TRUE
The watchdog timer is deactivated. In the event of a fail-
ure of communication, the analog output value will not be
set to either the manufacturer's or the user's default
value.
BOOLEAN RW 0x00 (0
dec
)
80n0:06 Enable user default
output FALSE
The manufacturer's value (0 V) will be output if the
watchdog timer triggers
TRUE
If the watchdog timer triggers, the user-specific output
value [
}
14] (object 0x80n0:13) will be output.
BOOLEAN RW 0x00 (0
dec
)
80n0:11 Offset User scaling offset compensation INT16 RW 0x0000 (0
dec
)
80n0:12 Gain User scaling gain compensation:
The gain is represented in fixed-point format, with the
factor 2
-16
.
A value of 1 for the gain factor therefore corresponds to
65536
dec
(0x00010000).
INT32 RW 0x00010000
(65536
dec
)
80n0:13 Default output
Definition of the user-specific output value [
}
14] that is
presented to the output if the watchdog timer for the
cyclic communication triggers.
INT16 RW 0x0000 (0
dec
)
Index 80nE AO Internal data Ch.1 - 4 (for 2 ≤ n ≤ 5)
Index (hex) Name Meaning Data type Flags Default
80nE:0 AO Internal data Ch.1
- 4 Maximum subindex UINT8 RO 0x01 (1
dec
)
80nE:01 DAC raw value DAC raw value INT16 RO 0x0000 (0
