In DN611A, the function enhancing old model DN611 and the problem are corrected.
A. Feature of DN611A
A-1 DN611A has passed ODVA conformance test
A-2 Compatibility with old model DN611
(a) DeviceNet communication function
It has not changed with old model DN611 (polling instruction / response mode and bit
strobe instruction / response mode are supported).
(b) The communication memory map between S controller and DN611A
It has not changed with old model DN611.
(c) Station status
A bit 0 displays network power supply normal / abnormal in DN611A. (In old model
DN611, it was a "reservation bit" )
ON : Network power abnormal
OFF: Network power normal
(d) Parameter setting request (slave device)
In specifing scan type of slave device, "the mix of polling and bit strobe" was
available at old model DN611, but this specification is stopped using in DN611A.
This is because the slave which uses the mix of polling and a bit strobe does not
exist.
(e) Operation mode control request
Although the bit 4 was "transmission start / stop bit" in old model DN611, this bit does
not influence operation of DN611A even if it is operated .
In DN611A, if it becomes the run mode and it will become the "transmission start", if it
becomes the standby mode and it will become "transmission stop."
However, In DN611A, ON/OFF of bit 4 is reflected in the bit 4 of station status for
compatibility with the radder program of old model DN611.
