Ack_Rei; Pass_Out/Qbad - TR-Electronic AD 582 Serie Gesamt-Bedienungsanleitung

Access to the safety-oriented data channel

6.2.1.3 ACK_REI

If a communication error is detected by the F-System for the measuring system, a
passivation of the measuring system is performed.
For an user acknowledgment in the measuring system after elimination of errors, a
positive edge at the tag ACK_REI of the F-IO data block is required, which is linked to
the memory bit M0.0, symbol name "Tag_1" in the example project.
An user acknowledgment is required:
●
After communication errors
●
after the start-up phase
An acknowledgement is only possible if the tag ACK_REQ = 1.
An user acknowledgment must be provided for each F-IO in the safety program via the
tag ACK_REI. This requirement has already been taken into account for the
measuring system.
6.2.1.4 IPAR_EN
The variable IPAR_EN is used to execute a preset adjustment function. The process
sequence for execution of this function is described in the device-specific user
manual.
A tag description of when the tags must be set/reset during a re-parameterization of
fail-safe DP standard slaves/IO standard devices can be found in the PROFIsafe
Specification from V1.20, or the documentation on the fail-safe DP standard slave/IO
standard device.
No passivation of the measuring system is triggered by IPAR_EN = 1!
With reference to the preset execution, the warning information contained in the
device-specific user manual must be observed!

6.2.1.5 PASS_OUT/QBAD

The tags PASS_OUT = 1 and QBAD = 1 indicate that a passivation of the measuring
system is present.
The F-System sets PASS_OUT and QBAD = 1, as long as the measuring system
outputs substitute values (0) instead of the cyclical values.
If a passivation is performed via the tag PASS_ON = 1, however, only QBAD = 1 is set.
PASS_OUT does not change its value for a passivation via PASS_ON = 1. PASS_OUT
can therefore be used for the group passivation of further F-IOs.
