Bit strobe
Change of state
Cyclic
*1 When the production inhibit time in setting is shorter than the link scan time of the module, the master transmits the data to the slave at
the scan interval of the module.
*2 The setting value of the production inhibit time must be same in all bit strobe connection.
EXPECTED PACKET RATE
(1)
The communication watchdog timer value for the
slave is set. When the communication between the
master and slave is cut out for the specified period
(the setting time  4), the slave node will carry out
the action specified with WATCHDOG TIMEOUT
ACTION.
(2)
When the expected packet rate setting value  1,
accordingly, the expected packet rate  0ms,
then, the expected packet rate  the production inhibit time must be observed.
(3)
When 1 is set, accordingly the expected packet rate
is 0ms, the watchdog timer monitor function is
invalid.
(1)
The communication watchdog timer value for the
slave is set. When the communication between the

the action specified with WATCHDOG TIMEOUT
ACTION.
(2)
When the expected packet rate setting value  1,
accordingly, the expected packet rate  0ms,
then, the expected packet rate  the production inhibit time must be observed.
(3)
When 1 is set, accordingly the expected packet rate
is 0ms, the watchdog timer monitor function is
invalid.
(1)
Specify the cycle to transmit the data from the slave
to the master.
(2)
When the expected packet rate setting value  1,
accordingly, the expected packet rate  0ms,
then, the expected packet rate  the production inhibit time must be observed.
(3)
Setting 1, accordingly the expected packet rate is
0ms, is not available.
PRODUCTION INHIBIT TIME
(1)
Minimum transmission cycle of slave = Set the
minimum time in which the slave can prepare the
transmit data.
The master transmits the bit strobe request to the
*1
slave in this time or longer.
(3)
When 1 is set, accordingly the production inhibit time
is 0ms, the master transmits the bit strobe request to
the slave at the scan interval of the module.
(1)
Set the minimum time in which the slave can receive
the data.
The master transmits the output data to the slave in
this interval. (It transmits the data to the slave even at
the timing of the output data conversion.)
(3)
When 1 is set, accordingly the production inhibit time
is 0ms, the master transmits the data to the slave only
at the timing of the output data conversion.
(1)
Specify the cycle to transmit the data from the master
*1
to the slave.
(3)
Setting 1, accordingly the production inhibit rate is
0ms, is not available.
