Expected
packet rate of
the nth slave
node
Communication
watchdog timer value
for slave node (ms)
01DD
H
+( -1) 8
Set the communication watchdog timer value for a slave node. When
communication between the master node and the first slave node is
interrupted for the period of time set here, the first slave node performs the
operation specified in buffer memory 01DE
H
.
Setting value = 0000
H
(default value) 500 ms
Setting value

the nth slave
node
Minimum
transmission interval
of slave node (ms)
01DF
H
+( -1) 8
Minimum transmission interval of a slave node: Set the minimum time that is
required for the slave node to prepare transmission data.
The master node sends the polling request and bit strobe request to the slave
node using this time interval.
Setting value = 0000
H
: (default value) 10 ms
Setting value
≠
0000
H
: Setting value -1 is the minimum transmission
interval (ms).
Note: (1) "n" indicates a number between 1 and b3.
