Network-Diagnosis "AS-iGuard " | Art.-No. DS004




The network diagnosis with the "AS-iGuard" aims at detecting rare or single events and thus heop tracking down their cause. For this purpose the AS-iGuard is permanently connected to the network, the normal configuration is learned and stored by pressing the pushbutton "Learn" and setting an event filter. The "AS-iGuard" will generate an alarm if the selected events are detected. In the event of an alarm a potential free relay contact is activated, an entry in the alarm protocol made and a message sent if the serial interface is connected.

The following events may be selected for triggering:

  • exceeding the nominal cycle time,
  • single telegram repetition,
  • third consecutive telegram repetition of a slave,
  • fifth consecutive telegram repetition of a slave and/or
  • configuration error and
  • earth fault.

A PC or laptop may be connected via a serial interface and an USB/Serial Converter with galvanic separation (ICS article UI002). An event protocol is sent via this link. It contains the slave address of the slave that caused the event. The "AS-iGuard" is, therefore, a diagnosis tool well suited e.g. for analysing the cause of sporadic tripping of safety monitors in safety at work applications.

The "AS-iGuard" is AS-iPower24V compatible (with the exception of the earth fault detection).

The dimensions of the unit are 95 x 75 x 23mm (without DIN rail and connectors)

AS-iGuard Control Software is supported by ICS GmbH, Tettnang, Germany on the following editions of Windows 10 – Windows 10 pro. AS-iExpert Control Software is supported on the in-market supported Windows 10 Current Branch for Business (CBB) servicing branches only and will be supported for the lifetime of the app until 2019.
