Description
Set the link scan time. (ms)
Set a larger value than "Maximum link scan time". If "Current link scan time" is
longer than the set link scan time, the module operates according to "Current
link scan time".
Select whether to set the slave node information in engineering tool or with
information stored in the module.
Set the node address (MAC ID) of the slave node on .
Set the message group.
Select the connection type for the I/O communication.
Set the number of input byte modules.
The bit module is calculated as 8 points equaling to 1 byte module.
Set the number of output byte modules.
The bit module is calculated as 8 points equaling to 1 byte module.
Set the number of input word modules.
Set the number of output word modules.
Set the number of input double-word modules.
Set the number of output double-word modules.
Set the expected packet rate for the slave node.
When the setting value is 0 (default): 200ms
When the setting value is other than 0: The setting value -1 is the expected
packet rate (ms)
Set the action taken when a watchdog timeout occurs in the slave node.
(Default)
Same as the following timeout.
TIMEOUT
The connection times out.
The communication is manually stopped, and is not recovered until manually
restarted.
AUTO DELETE
The connection is automatically deleted.
The communication is stopped temporarily, and automatically restarted.
The output is cleared once.
AUTO RESET
Communication continues while holding the connection.
Set the production inhibit time.
The setting value varies depending on the connection type.
When the setting value is 0 (default value): 10ms
When the setting value is other than 0: The setting value -1 is the minimum
transmitting interval (ms).
