Safety I/O Communications as Safety Master
Safety I/O communications are used to exchange data automatically with
Safety Slaves without user programming.
To perform safety I/O communications with other slaves, the following items
are required:
1. Registration of slave devices in the NE1A-series Controller.
2. Safety I/O connection settings.
Safety Master Specifications
Safety Slave Allocations
Safety Slaves that communicate with the NE1A-series Controller are allocated
automatically in the Controller’s I/O memory based on the settings made from
the Network Configurator. In the Logic Editor, slave I/O is displayed as I/O
tags. Using these I/O tags allows a user to program without being aware of
specific memory addresses in the NE1A-series Controller.
Safety I/O Connections
Number of connections
Pre-Ver. 1.0 Controllers: 16 max.
Controllers with unit version 1.0 or later: 32 max.
Maximum data size
16 bytes of input or 16 bytes of output (per connection)
Connection type
Single cast or multicast
