LEDs are powerful diagnostic indicators on just about all AS-Interface devices. The simple rule is that "green" is good and “red" requires someone’s attention.  Outputs are an interesting exception where "amber" indicates that the output is ON.  The AS-Interface Maintenance and Service Guide(PDF) also lists the LED states on the "consortium" Safety Monitor.

Exchanging an AS-Interface Safety Monitor is a simple process, and in this episode Tim explains how this is done using the "consortium" Safety Monitor with the dedicated transfer cable.  Tim also covers the procedure for the newer AS-Interface solutions (KE4 and K30) where the configuration is stored on a memory card.

The AS-Interface Maintenance and Troubleshooting Guide discusses setting up a network using the convenient 'Store+Run' and 'Store+PRJ Mode' function. 

In this episode, Tim and Helge talk about setting up a network using these functions and also discuss a number of other, very important features including error counters and fault detectors.

In this week's discussion, Tim Cicerchi and Helge Hornis continue their conversation about The AS-Interface Maintenance and Troubleshooting Guide. The guide explains what users can do with the AS-Interface addressing handheld unit. Hints from the guide include:

  • --Assign an address to any AS-Interface module
  • --Read inputs and set outputs
  • --Read the profile (IO and ID codes)

In this week's discussion, Tim Cicerchi and Helge Hornis call out specific aspects of The AS-Interface Maintenance and Troubleshooting Guide. The guide is a very useful booklet that helps new and experienced AS-Interface users during planning, installation, and troubleshooting. Tips include:

  • --Use certified modules
  • --Always follow the most basic installation rules .. there are not that many
  • --Do not use shielded or twisted cable

In this week's episode, Helge Hornis continues his discussion with David Fink, National Account Manager at Pepperl+Fuchs, about controlling and monitoring valve position using AS-Interface in combination with valve position sensors. 

  • --The components that comprise a valve assembly
  • --AS-Interface controls the valve assembly or solenoid valve
  • --How to know if the valve is stuck?
  • --Can AS-Interface control an actuator valve without a solenoid?
  • --Are different manufacturer valves, actuators, and valve position sensors compatible?
  • --Can manually operated valves be equipped with a valve position sensor and AS-Interface?

In this week's episode, Helge Hornis continues his discussion with David Fink, National Account Manager at Pepperl+Fuchs, about using AS-Interface for valve position monitoring.

  • --What is the output of the solenoid driver on a valve position sensor?
  • --Differences between standard sensors with no solenoid output and valve position sensors with solenoid output.
  • --AS-Interface modules and their uses for valve position sensing.
  • --The myth that AS-Interface is only for low current consumption/low wattage types of applications.

In this week's episode, Helge Hornis talks to David Fink, National Account Manager at Pepperl+Fuchs, about how to use AS-Interface to monitor valve position. David first gives an overview of the basic components of a valve assembly. This includes quarter-turn valves mounted to a pneumatic actuator. The actuator is equipped with a dual-position inductive sensor a target or puck, and a solenoid valve:

  • --How does the whole valve assembly work together?
  • --Do you need to pay attention to where the puck is mounted?
  • --How is AS-Interface used to control the position of industrial valves?

During last week's episode, Tim talked about the basic AS-Interface safety monitor. There is a second hardware version that can operate a small AS-Interface network without the need for a dedicated AS-Interface power supply. Today, Tim covers the important points of the VAS/M-2A8L-KE4-8SE-C1 safety monitor.

Products noted in this episode:

VAS-2A8L-KE4-8SE safety monitor

VAZ-1E4A-KE4-Z/R-S contact expansion module
