The send delay function is used to prevent immediate transfer to the serial
port of a FINS command after it has been received by the Serial Communica-
tions Unit/Board and converted into the specified protocol. With this function,
the converted command is sent to the serial port after a set time. (The default
is 0 s, and the setting range for user-specified value is 0 to 300 s. Set this
function in the DM Area.)
For example, use the send delay function to prevent loss of send frames when
receive processing at the connected device does not provide sufficient speed.

The Serial Communications Unit/Board can hold processing on standby for up
to five FINS commands for the Serial Gateway. If a sixth FINS command is
received at the serial port, a FINS error response (end code: 2605 hex (ser-
vice executing)) will be returned to the source of the FINS command.
When the Serial Gateway is executed, routing tables are either required or
optional as follows:
• Routing tables are required to treat a serial communications path as a
network when converting FINS messages to Host Link FINS for serial
conversion via the network.
• Under other conditions, routing tables are optional.
The details are provided in the following tables.
