114 Safety Network Controller NE0A-SCPU01

Functions

The following function blocks are available for designing safety circuits with the NE0A-SCPU01.

These function blocks can be selected and assembled using the interactive wizard format to efficiently design safety applications.

Note: There is a possibility that safety cannot be maintained when an OR part or an AND/OR part is selected for input logic, or an OR/AND part is selected for output logic. Sufficiently

confirm safety prior to use.

Classification of function block

for safety circuit designs

Application

Function blocks for safety input

devices and setting input filter

times

The following six parts can be selected for use as safety input devices.

For Category 3 or 4 compliance, the filter monitoring time between signals can also be adjusted with redundant wiring for the necessary

safety devices.

Emergency Stop Switches

Safety Door Switches

Limit Switches

Safety Light Curtains

Enabling Switches

Mode Selectors

Logic function blocks for input

conditions

Select a Safety Light Curtain as the safety input device, and select a muting function when required.

No setting Uses the ON/OFF status from the safety input device exactly as it is.

OR operation

• For switching maintenance areas with a Mode Selector.

• For applications such as a Safety Light Curtain muting function.

AND/OR operations

AND operation

OR/AND operations

Function blocks for resets Selects manual or auto reset.

Logic function blocks for output

conditions

For applications such as stopping all outputs for multiple safety devices.

No setting Uses the ON/OFF status of the safety signal exactly as it is.

AND operation

Selects the interlock conditions for the safety signal.

OR/AND operations

Function blocks for setting the

welded contact check

Used to check the safety condition of an output device.

No setting No checking of the output device (used for Category 2 or lower).

EDM

Used to check for contact welding in a Relay or Contactor.

Also used to change the setting for monitoring time.

Function blocks for safety output

devices and setting output delay

times

For setting an auxiliary output (to output an error condition) and for setting the output delay.
