LINbus I/O Module

LIN I/O is the communication adapter between production automation and the LIN test object.

This device variation has been conceived for fixed installation on a rail or in a switch cabinet. LIN I/O is the communication adapter between production automation and the LIN test object. The connection to the automatic testing device or SPS is effected optionally via high-speed CAN and/or 24V digital I/O - in both cases potentially separated from the LIN test object. The test object can be fed in a short-circuit protected manner via the LIN I/O. As a unique particularity, the current uptake of the test object is measured and can be used in the evaluation.

The internal signal processing makes it possible to pre-process the LIN data, for example for checking the limiting values or plausibility, or for the end-of-line calibration of the control devices. The SPS can thus be freed up and the LIN interface can independently carry out simple sequences and deliver - for example - "good/bad" evaluations to the SPS.

In spite of the deviation in hardware appearance, the LIN I/O is compatible with the other members of the family of tools.

Performance Characteristics of LIN I/O:

• Emulation and Analysis of LIN nodes / LIN subsystems, simulation of bus participants not actually present
• Wakeup / Sleep
• Event-based signal configuration and sequence control
• LIN bus error recognition, playback via CAN, LED and port possible
• PC program Visulin for recording and displaying measurement data, and also for configuring the emulator
• Simple integration into automated test environments (LabView, HP VEE, and others)

Equipment:

• Status display via LED's
• Ohmic bus termination (master/slave/stress/overload) switchable by means of software
• galvanically separated digital inputs/outputs (like digital I/O module)
• LED status display for digital ports
• 4 analog inputs
• 2 analog outputs, trigger creation
• 1 current measurement channel for current uptake of the test object
• Housing for the top hat rail assembly, 200 x 105 mm
• Connections designed as plugable rows of pins
