Overview

The safety monitor is the centerpiece of ASIsafe. A safe applica-

tion is configured using a PC and the safety monitor. Various ap-

plication-specific operating modes can be selected for this.

They include, for example, an EMERGENCY-STOP function,

tumbler and selection of stop Category 0 or Category 1.

To be able to make full use of the AS-Interface diagnostics op-

tions, the monitor can also be operated with an AS-Interface ad-

dress if required. With the help of the diagnostics block for

STEP7, which is included on the ASIsafe CD, the full diagnostics

spectrum can be processed further in the higher-level PLC.

The monitor comes in two expansion levels:

• Basic safety monitor with starter set of modules and basic

functionality

• Expanded safety monitor with expanded features and func-

tionality

Both expansion levels are available with one or two enabling cir-

cuits with two-channel configuration.

The safety monitor is used in an AS-Interface bus system to mon-

itor protective devices, e.g. EMERGENCY-STOP switches. It is

classified in Safety Category 4 according to EN 954-1.

According to IEC 61508 the safety monitor can be used in loops

up to SIL3. The user must calculate the PFD value of the total

loop.

Note: Depending on the choice of safety components used, the

complete safety system may also be classified in a lower safety

category.
