Example 1: The signal states of digital output lines 1 and 3 are to be combined by a logical AND
operation. The result is to be written to the digital output line 2. The mask for selection of the
digital output lines to be combined is specified in hex format. Send:

Example 2: The signal states of digital output lines 2 and 3 are to be combined by a logical OR
operation. The result is to be written to the digital output line 1. The mask for selection of the
digital output lines to be combined is specified in decimal format. Send:

Using the Analog Input
How to Work with the Analog Input - Overview
With models E-727.xxxA and .xxxAx, four analog inputs are available on the Analog I/O socket
(p. 228). In the firmware of the E-727, the analog input lines are represented by the input signal
channels 4 to 7.
The voltage range of an analog input (±5 V or ±10 V) can be configured via the value of the
corresponding Sensor Range Factor parameter (ID 0x02000100).
You can use an analog input line as follows:

Connect an external sensor

Connect a source for control value generation
INFORMATION
E-727.3SDA, .3SDAx, .3RDA and .3RDAx models only:
Input signal channel 4 can also be used for sensor input on the socket for piezo stages (p. 226).
The corresponding configuration is done via the value of the Sensor Range Factor parameter (ID
0x02000100) as follows:

1: Use with a piezoresistive or strain gauge sensor (input via pins 6, 24, 25)
 2: Use with a PT1000 temperature sensor (input via pins 1, 20)
For further details, see the description of the input signal channels in „Axes, Channels, Functional
Elements“ (p. 22).
Irrespective of the intended usage, the analog input values must first be scaled to suitable position
values (see "Scaling the Analog Input" (p. 87)). Then, to set the usage of the analog input, it is
furthermore necessary to change certain controller parameters. See "Use as Control Value
Generation Source" (p. 90) or "Use as External Sensor Input" (p. 91) for details. Analog input lines
which are not used should be deactivated to avoid interferences, see "Deactivation of Unused
Analog Input Lines" (p. 92) for details.
