2.1.2 Interface
• Ethernet LAN Connection
• Socket Communication using TCP/IP
(External Host: Server, Device: Client)
2.1.3 Error Processing
• NAK Response (other than ACK) Received
When the "NAK (0x15)" is received, the data is transmitted again.
Note: The frequency control must be made on the host computer
side.
• Time-Out: Monitoring the normal performance of the external host
computer
The machine monitors if the "ACK" response (*2) is received from
the external host computer for the specified period of time (*1) after
the component shortage data has been transmitted to the external
device.
When the expected response is not received within the specified time,
the data is discarded.
(*1) The time can be specified in the "COMMUNICATION TIMER" data
box at the display.
Data Input Range: 0.1 to 20.0 seconds (in increments of 0.1 sec-
ond)
(*2) When the external host computer has normally received the data, it
sends back an "ACK (ASCII Code: 0x06)".

• The checksum calculation method can be specified on your side.
Ref.: The ASCII codes in the command and data sections are
added. When the total of each 8 bits becomes "0" (zero), the
checksum is regarded as "OK".
The character position of the checksum is fixed.
