Standard Slave Function Section 4-6
Selecting Connection Type
Any of the following 4 connection types can be selected. Output data cannot
be set for Bitstrobe data because Bitstrobe data cannot be output from the
Standard Master. Also, the maximum data size for Bitstrobe data input to
Standard Master is 8 bytes. COS and cyclic connections cannot be used at
the same time.
•Poll
• Bitstrobe
•COS
• Cyclic
Setting I/O Tags
Set the input data blocks and outputs data block to use for the selected con-
nection. Multiple data blocks can be set for Slave 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 bytes, however, can be set for 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 specific memory
addresses in the NE1A-series Controller.
Setting Additional Status
When the I/O type of a 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.
Pre-Ver. 1.0 Controllers
Controllers with Unit Version 1.0 or Later
Note For the NE1A-SCPU01-V1, N = 2 and M = 1. For the NE1A-SCPU02, N = 5
and M = 2. The sizes of the local input status and test output/muting lamp sta-
tus data can be specified in bytes.
Setting Local I/O Monitor Data
If the I/O type of the Safety Slave I/O is set to Slave IN for a NE1A-series
Controller with unit version 1.0 or later, the following local I/O monitor informa-
tion can be added to the transmission data after the status information. Refer
to 4-3-3 Remote I/O Area Data Configuration for details on the local I/O mon-
itor information.
