2.1.1.2 General Description
The 750-562 analog output module generates output voltages in the range
from 0 ... 10 V or –10 ... +10 V for the field area.
The module has two short circuit-proof output channels and enables the direct
cabling of two 2-line actuators on the connections AO 1 and ground or AO2
and ground. The output of the signals occurs via AO 1 or AO 2.
In addition, the sense lines from 4-line actuators can be connected to the
connections Sense AO1 and +Sense AO1 or Sense AO2 and +SenseAO2.

General Description
WAGO-I/O-SYSTEM 750
I/O Modules
The integrated drivers of the end levels are temperature-monitored.
Both output channels have a common ground potential.
The output signal is electrically isolated from the system level and will be
output with a resolution of 16 bits.
The readiness for operation and the disturbance-free I/O module
communication of the module is indicated with one green function LED per
channel.
An overload or a short circuit of an output is indicated by one red error LED
per channel.
The calibration data is stored individually for each operating mode and can be
scaled. For the process data output, a lower and an upper limit value can be
specified.
Furthermore, a variety of adjustment possibilities can be made, including
calibration data switching, numeric format and numeric display switching,
output behavior for I/O module timeout, (repeat) switch-on delay after
excessive temperature switch-off, etc. The individual output modules can be
arranged in any combination when configuring the fieldbus node. An
arrangement in blocks is not necessary.
The internal system supply is used for the power supply. The field power
supply is only forwarded to the downstream I/O modules.
The system voltage is monitored for undervoltage.
The output module receives the 0 V potential and the 24 V for downstream
I/O modules via an upstream I/O module or via a supply module. Power
connections are made automatically from module to module via the internal
power jumper contacts when the output modules are snapped onto the DIN
rail.
Warning
The maximum current that is permitted to flow through the power jumper
contacts is 10A. When configuring the system, ensure that this total current is
not exceeded. If this should happen, an additional supply module has to be
used.
The output module can be operated on all couplers/controllers (with the
exception of the economy variants 750-320, -323, -324, and -327) of the
WAGO-I/O-SYSTEM 750.

2.1.1.7 Process Image
The analog output module 750-562 transmits 16 Bit data and 8 status bits per
channel.
The digitalized output value is transmitted in a data word (16 bits) as output
byte 0 (low) and output byte 1 (high) via the process image of the
coupler/controller.
This value is represented with a 16 bit resolution on bit B0 ... B15.
Some fieldbus systems can process the status information using by means of a
status byte.
However, processing of the status byte via the coupler/controller is optional,
which means that accessing or parsing the status information depends on the
fieldbus system.

Setting of the upper and lower limit value depending on the numeric
format:
In the +/- numeric ranges, the limit values must be re-calculated to a positive
equivalent in the range from 0 ... 65535 (see table).
1. Example: twos complement

Process Image

Lower limit: -10 -> underrange limit value (register 41): 32758
Upper limit: +10 -> overrange limit value (register 42): 32778
2. Example: leading sign/amount
Lower limit: -10 -> underrange limit value (register 41): 32758
Upper limit: +10 -> overrange limit value (register 42): 32778
Setting the upper and lower limit value depending on a scaling:
3. Example: scaling
–10000 should correspond to –10 V, +10000 should correspond to +10 V.
This way, the scaling factor is: 32767 / 10000 = 3,2767.
3,2767 * 256 (increment with scaling) = 839.
839 is the amplification factor (gain, register 34). The offset (register 33)
remains 0.
If limit values should now be determined, these must be multiplied by 3.2767
and then re-calculated as in the first example to a numeric equivalent in the
range from 0 ... 65535.
