Complementary information
•
T
he main module, the internal logic of all expansion modules and gateways on the
FLEXBUS+ as well as their inputs (I1 … I8) and test outputs (X1 to X8 as well as
XY1 and XY2) are supplied electrically only via the system plug. The outputs are
supplied separately, however (Q1 to Q4, Y1 to Y6 as well as IY7 and IY8).
•
The data stored in the system plug is also retained in the event of any interruption
in the voltage supply.
•
Clearly and unambiguously mark all connections (connecting cables and plug con‐
nectors) on the safety controller to avoid mix-ups. The Flexi Soft system features
several connections of the same design. Therefore, you must make sure that no
unplugged connecting cables or plug connectors are accidentally connected to the
wrong connection point.
3.4.6 FX3-XTIO I/O module
Overview
T
he FX3-XTIO module is an input/output expansion module with 8safety inputs and
4safety outputs. It has 2test pulse generators, one for test output X1 and one for test
output X2.
The FX3-XTIO module supports the following functions:
•
Monitoring of the connected safety devices
•
Forwarding of information at inputs I1 to I8 to the main module
•
Receipt of control signals from the main module and corresponding switching of
outputs
•
Fast shut-off: direct shutdown of the actuators connected to the module.
This reduces the response time of the overall system. The response times of the
de
vices at the inputs and outputs are extended by 8ms in order to shut down the
outputs. Run times on the FLEXBUS+ internal bus and the logic processing time
are not relevant in this case.
•
A
ctivation or deactivation of the test signals at outputs Q1 to Q4
