Number of Receive Bytes (Response)
The number of bytes of receive data from the Originating Node Address to
the end of the response is returned in hexadecimal.
Originating Node Address (Response)
The node address of the responding NE1A-series Controller is returned in
1-byte hexadecimal.
Read Data (Response)
The I/O data from the specified area is returned.
The address offsets and bit assignments for reading the local inputs, local
outputs, and test outputs are given in the following tables.

For the NE1A-SCPU01 or NE1A-SCPU01-V1, status can be read for 16 ter-
minals, i.e., safety input terminals No. 0 to 15. For the NE1A-SCPU02, status
can be read for 40 terminals, safety input terminals No. 0 to 39.

For the NE1A-SCPU01 or NE1A-SCPU01-V1, test output status can be read
for 4 terminals, i.e., test output terminals No. 0 to 3. For the NE1A-SCPU02,
test output status can be read for 8 terminals, i.e., test output terminals No. 0
to 7.
