Flexi Classic gateways
3 Flexi Classic gateways
T
he Flexi Classic gateways generate non-safety-related fieldbus data (status bytes) for con-
trol and diagnostics purposes. These status bytes contain the input and output states as
well as fault and status information. The nature and scope of the diagnostic data are de-
f
ined during planning and for the mapping.
I
n addition, you can save status bytes and diagnostic data on a PC with the aid of the PRO-
FIBUS-DP Master Simulator and the file flexi_config_list.xls, and document the settings for
the entire system (see section 4.2.2 “Documenting with PROFIBUS-DP Master Simulator”.
A Flexi Classic gateway has four short circuit-proof application diagnostic outputs for con-
trolling non-safety functions. It is not allowed to connect any safety-related loads or inputs
of the Flexi Classic system with a safety function to these four application diagnostic out-
puts.
The operation of the safety-related functions of the Flexi Classic system is not affected by
the bus coupling. There is no information flow from external fieldbus systems over the
gateway to the safety system.
The modules are not suitable for operation on a safety fieldbus. They do not monitor the
functionality of the fieldbus or the digital application diagnostic outputs (X1-X4).
A Flexi Classic gateway can only be operated on a Flexi Classic system. It does not have a
dedicated voltage supply. It is only possible to use one Flexi Classic gateway per system.
The gateways are fitted in a 22.5 mm wide housing for 35-mm rails in accordance with
EN 50022. The devices have a removable screw terminal for each of the control outputs.
3.1 System information transmitted by the modules
system configuration
– input states on all Flexi Classic modules
– state of all safety outputs (Q1-Q4 or O
P
, Q1, Q2 and O
N
)
– control circuit configuration for all Flexi Classic modules
– settings for all program and function switches on the Flexi Classic modules
error and status information on all Flexi Classic modules
– erroneous system configuration, feedback circuits
– exceeding the synchronous monitoring time (closing a safety door)
– process error on dual-channel applications (e.g. on opening/closing a safety door)
– cross circuit on the inputs
– cross-circuit on the safety outputs, internal error (error classes)
