Safety Slave I/O Setting
Set the Safety Slave I/O as follows:
1. Select the I/O type.
2. Set the I/O tags.
3. Set additional status.
4. Set additional local I/O monitor data.
Selecting the I/O Type
Setting I/O Tags
Set the input data blocks and output data blocks to use in the program for the
Safety Slave I/O. Multiple data blocks can be set for Safety Slave I/O. The size
of the data block can be selected from BOOL (1 byte), BYTE (1 byte), WORD
(2 bytes), or DWORD (4 bytes). A maximum of 16 bytes, however, can be set
for Safety Slave I/O.
I/O tags defined for data blocks can be used in the Logic Editor. Using I/O tags
enables the user to program without being aware of the NE1A-series Control-
ler’s specific memory addresses.
Setting Additional Status
When the I/O type of the Safety Slave I/O is Slave IN, the following status
information can be added to the first line of the transmission data. Refer to 4-
3-3 Remote I/O Area Data Configuration for details on each status.
