8.3.1
Connecting the Digital Outputs
Tools and Accessories
■
Suitable cable, e.g., C-170.IO IO cable with open end, available as an optional accessory
■
Device to be triggered having digital input for TTL signals
Information
Digital output signals are available on pins 5, 6, 7 and 8 of the
I/O socket.
Connecting a Device to be Triggered
1. Connect an appropriate device to one of pins 5, 6, 7, and 8 of the
I/O socket of the
E-871.1A1N.
8.3.2
Connecting the Digital Inputs
Tools and Accessories
■
Suitable signal source:
■
If the digital inputs are to be used in macros, it is possible for example, to connect the
C-170.PB pushbutton box, which is available as an optional accessory.
■
If the digital inputs are to be used as the source for the reference and limit switch
signals of an axis, the signal level may only change once across the entire travel range.
■
If necessary: Suitable cable, e.g., C-170.IO IO cable with open end (available as an
optional accessory)
Information
Digital TTL input signals can be fed to the E-871.1A1N via pins 1, 2, 3, and 4 of the
I/O socket.
The digital inputs can be used as follows:
■
Use in macros
■
Source for the reference point switch and limit switch signals of the axis
Information
The digital inputs on the
I/O socket can also be used as analog inputs.
■
Digital: TTL
■
Analog: 0 to +5 V
Connecting a Digital Signal Source
1. If you want to use the digital inputs in macros or as switch signals: Connect a suitable
signal source to one of the pins 1, 2, 3, or 4 of the
I/O socket of the E-871.1A1N.
2. If you want to use the digital inputs for HID control, follow the instructions in "
".
8.3.3
Digital Output Signals
The number of output lines available on the E-871.1A1N can be queried with the
command.
External devices can be triggered via the digital outputs of the E-871.1A1N. Potential
applications:
■
Linking the trigger output to the motion of the axis (
; query with
)
■
Direct switching of output lines (
