Serious injury may possibly occur due to loss of required safety functions.
The data attributes handled by standard I/O communications are non-safety data.
The necessary measures for safety data are not taken for this data during data
generation. Therefore, do not use this data to configure the Safety Control
System.
Any of the following 2 connection types can be selected.
• Point-to-point
• Multicast
When the I/O type of a Target I/O is Target IN, the following status information
can be added to the first line of the transmission data. The contents of the sta-
tus is the same as for DeviceNet communications. Refer to 4-3-3 Remote I/O
Area Data Configuration for details on each status.
Tag Name
General Status
Local Input Status 1 to N
Local Output Status
Test Output/Muting Lamp Status 1 to M
*1 For the NE1A-SCPU01-EIP, N = 2 and M = 1. For the NE1A-SCPU02-EIP, N =
5 and M = 2. The sizes of the local input status and test output/muting lamp
status data can be specified in bytes.
If the I/O type of the Target I/O is set to Target IN for a NE1A-series Controller
the following local I/O monitor information can be added to the transmission
data after the status information. Refer to 4-3-3 Remote I/O Area Data Config-
uration for details on the local I/O monitor information.
Local I/O Monitor
Local Input Monitor 1 to N
Local Output Monitor
*1 For the NE1A-SCPU01-EIP, N = 2. For the NE1A-SCPU02-EIP, N = 5. The
sizes of the local input status and local input monitor status data can both be
specified in bytes.
Set the input data blocks and outputs data block to use for the selected con-
nection. Multiple data blocks can be set for Target I/O. The data block size can
be selected from BOOL (1 byte), BYTE (1 byte), WORD (2 bytes), or DWORD
(4 bytes). A maximum of 16 input bytes or 16 output bytes, however, can be
set for the Target 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 specific memory
addresses in the NE1A-series Controller.
When the I/O type of a Target I/O is Target IN, data for communications
between with a Safety Slave performing DeviceNet Safety communications
can be added after the I/O tags.
