Specifications Section 1-6
Converted format • CompoWay/F commands
• Modbus-RTU commands
• Modbus-ASCII commands
• Host Link FINS commands
Enabled serial com-
munications mode Serial Gateway mode or protocol macro mode
Queuing functions Up to five FINS commands can be converted and then queued
for processing.
Protocol macro exe-
cution processing When a FINS command is received during protocol macro
execution, the Serial Gateway is executed using an interrupt
between steps in the communications sequence. If the next
step is a RECEIVE command, the Serial Gateway will not be
executed until the next step. For other conditions, the interrupt
is executed immediately.
Note The reception buffer is cleared during Serial Gateway
execution.
Note The Serial Gateway can be prohibited in protocol macro
mode by turning ON the Serial Gateway Prohibit Switch
in the CIO Area.
Response timeout
monitoring The time is monitored from when the message is converted
into the specified protocol using the Serial Gateway until the
response is received (in Serial Gateway mode or protocol
macro mode).
Default: 5 s (setting range: 0.1 to 25.5 s)
Note When a timeout occurs, the FINS end code (0205 hex:
Response timeout) is returned to the source of the FINS
command and a response is received after a timeout
occurs.
Send start timeout
monitoring The time is monitored from when the FINS command is
received until it is converted into the specified protocol and
starts to be sent (in protocol macro mode only).
Default: 5 s (setting range: 0.1 to 25.5 s)
Note When a timeout occurs, the FINS end code (0204 hex:
Remote node busy) is returned to the source of the
FINS command. The send processing will not be exe-
cuted and the received FINS command will be dis-
carded.
Send delay The time can be set from when the message is converted into
another protocol using Serial Gateway conversion until the
data is actually sent. (Serial Gateway or protocol macro mode)
Default: 0 s (setting range: 0.01 to 300.00 s)
