Master function parameter setting area
This area is used to set the master function parameters.
Set the information such as the connection type and number of I/O points for the I/O communications with each slave node
(63 at maximum).
■Master function parameters (Un\G468 to Un\G975)
When setting the master function parameters using the auto configuration, refer to the following.


Specify this item to stabilize the link scan time.
(Setting range: 0 to 65535ms (FFFFH))
Lower byte
• 00H to 3FH: Node address of the 1st slave node (MAC ID) 0 to 63
Upper byte
• 01H: Node supporting UCMM and using one of message group 3, 2,
or 1
• 03H: Node supporting UCMM and using the message group 1
• 04H: Node not supporting UCMM (group 2 dedicated server)
• 80H: Reserved node
Select the connection type for the I/O communication.
• 0001H = Polling
• 0002H = Bit strobe
• 0004H = Change of state
• 0008H = Cyclic
Lower byte: Number of input byte modules
Upper byte: Number of output byte modules
(Set in hexadecimal.)
The bit module is calculated as 8 points equaling to 1 byte module.
Lower byte: Number of input word modules
Upper byte: Number of output word modules
(Set in hexadecimal.)
Lower byte: Number of input double word modules
Upper byte: Number of output double word modules
(Set in hexadecimal.)
Set the expected packet rate for the slave node.
The setting details vary depending on the connection type.

Page 40 Details on the expected packet rate and the production
inhibit time
• 0000H: 200ms (default value)
• Other than 0000H: Setting value -1 (ms)
Set the operation taken when a watchdog timeout occurs in the slave
node.
• 0000H: Equivalent to the following TIMEOUT (default value).
• 0001H: TIMEOUT
The connection becomes timeout.
The communication is manually stopped and is not recovered until it is
manually restarted.
• 0002H: AUTO DELETE
The connection is automatically deleted.
The communication is stopped and is automatically restarted.
The output is cleared once.
• 0003H: AUTO RESET
The communication continues while holding the connection.
The output is not cleared.
Set the production inhibit time.
The setting details vary depending on the connection type.
(Setting range: 0 to 65535ms (FFFFH))
0000H: 10ms (default value)
Other than 0000H: Setting value -1 (ms)
Same as that of the 1st slave node
