Communication; Group Error Messages - Eaton PXS24 Technisches Handbuch

COMMUNICATI-
ON
"In" is used for control purposes:
Low: No voltage at output
High: Module is live
Note: The input is equipped with an internal pull-up resistor, so that the module is live without any
external connection.
Reset (remotely): Low > High
Note: An "off" signal always takes precedence (irrespective of whether it originates at the selector
switch at the front or at the "In" input), meaning the module will remain inactive until both signals
have switched to "on"!
"Out" trip signal:
Low: Module is live, no error
High: Module has tripped or was switched off manually
The GND connection at the communication port is intended for communication purposes only and
shall therefore not be loaded with currents over 200mA!
The communication port inputs and outputs conform to IEC/EN61131-2. It is therefore possible to
connect the module directly to a PLC, or to use it to control loads.
Note: The communication link is implemented via a dedicated port that is not available in the "Econ-
omy" series.
GROUP ERROR
If individual error messages are not required, the trip outputs ("Out") of several PXS24 modules can

be connected. A total of at most 30 modules can be connected in this way.
Note: This feature cannot be used simultaneously with the subsequent control.
