Note
Output When Multiple Items Are Set
The items that are set for output data numbers 0 through 7 are output to the PLC reception buffer in ascending order,
one data item at a time (16-bit units). Each time a data item is output, the GATE signal turns ON.
When this occurs, the first data item that was output to the PLC reception buffer (data 0) is overwritten by the next
output data item (data 1).
Therefore, the data output to the PLC reception buffer must be saved to PLC memory each time the GATE signal
turns ON for each data item.

Data Output Control with Handshaking (p.32)
Data is output as 2's complement binary data.
Information on 2's Complement
Refer to Definitions of Basic Terms in the Vision System FH/FZ5 Series User's Man-
ual (Cat. No. Z365).
Data is output expressing 1 digit with 4 bits and expressing a 3-digit integer and sign
with 16 bits.
• Bits 12 to 15
These bits give the sign. (positive: 0000, negative: 1111)
• Bits 0 to 11
Every 4 bits express 1 digit from ones place (bits 0 to 3: 1st digit) to the hundreds
place (bits 8 to 11: 3rd digit).
