750-667/000-003 4FDI/4FDO 24V/2A PROFIsafe V2 iPar
Test Mode
The test mode is intended for starting up and configuring the F I/O module with
the iPar server and is initiated by the F I/O module upon receiving the F
parameter F_iPar_CRC = 0. This eliminates the check of F_iPar_CRC against
iPar_CRC. All digital inputs and power outputs are passivated during test mode
and the F I/O module outputs the substitute values (failsafe values) instead of
actual process values to the controller. According to the PROFIsafe specification,
the test mode is indicated visually by 2 Hz flashing of the parameterization LED
(LED H) in green on the F I/O module.
U
User acknowledgement (Operator Acknowledge (OA))
Prompt for user acknowledgement (operator acknowledgement) that evokes
start-up of a machine or system.. User acknowledgement is necessary for the
F I/O module, for example, after detecting errors by the F I/O module and their
resolution by maintenance personnel and is initiated from the control level.
V
Valence Analysis
The valence analysis is the analysis of two input signals either according to the
rules of equivalence (equality) or according to the rules of antivalence
(difference).
W
WAGO Parameterization Tool
The WAGO parameterization tool is required to configure the F I/O module. This
refers to the WAGO-I/O-CHECK 3.x and WAGO Safety Editor
75x 2.x manufacturer tools (see also "WAGO-I/O-CHECK").
WAGO Safety Editor 75x 2.x
The WAGO Safety Editor (SEDI) 75x 2.x is required together with the
WAGO-I/O-CHECK 3.x to configure the F I/O module. SEDI is the CPD tool for
WAGO F I/O modules (see also "CPD Tool (Configuration Parametrization and
Diagnosis Tool)").
WAGO-I/O-CHECK
WAGO-I/O-CHECK is a manufacturer tool used to configure WAGO I/O modules.
To parameterize the F I/O modules, WAGO-I/O-CHECK 3.x and WAGO Safety
Editor 75x 2.x are required (see also "WAGO Parameterization Tool").
