Yaskawa Remote Serial Communication Controller LAN Node PCB for use with Microtrac DSD LAN - Manual (Page 11)

Number defined in the PAC diagram. The msb
of the SUBCHANNEL # is at offset 4.
The DCP is the decimal point location to
be used to display the numeric value. The DCP
value is equal to the number of digits to the right
of the decimal point.
RDU Select Menu Item
(028H)
This message is sent from a drive to the
Remote node in order to select a menu item for a
particular RDU. This type of message makes it
possible to change menu items without forcing
the user to press any keys at the Remote node.
When the Remote node receives this message,
it will send a Display Abort message to the drive
corresponding to the currently selected menu
item. It will then send a Display Node Request
message to the drive corresonding to the newly
selected menu item.
[ MSG TYPE = 028H | RDU # | MENU ITEM # ]
0 1 2
The RDU # indicates which Remote node
channel the information is intended for.
The MENU ITEM # is a value between 1
and the maximum menu size, which points to the
desired parameter within the RDU.
Display Logic Message ASCII
Responsse
(029H)
The drive sends this message to the
Remote node only once, after receiving the
Display Node Request, to provide the ASCII
string used as a legend for the display and the
initial logic display value. When the Remote
node receives this message, it knows that the
data is to be displayed only, and will not allow
any modification of the value. Subsequently, the
drive will send only the logic value to the Remote
node, with use of the Display Logic Value
Response message, when the data changes and
at regular 4 second intervals.
[ MSG TYPE = 029H | RDU # | BOTTOM LINE
ASCII
0 1 2-17
TEXT | TOP LINE ASCII TEXT | VALUE ]
18-33 34
The RDU # indicates which Remote node
channel is to receive this information.
The BOTTOM LINE ASCII TEXT is the
legend for the data; the first character of the
string is at offset 2.
The TOP LINE ASCII TEXT contains the
drive name and the units for the data; the first
character of the string is at offset 18.
The VALUE contains the initial value of
the data; a logic 0 is represented by VALUE
equal to 0, and a logic 1 is represented by
VALUE equal to 0FFH.
Display Logic Variable ASCII
Response
(02AH)
The drive sends this message to the
Remote node only once, after receiving the
Display Node Request, to provide the ASCII
string used as a legend for the display and the
initial logic display value. When the Remote
node receives this message, it knows that the
data may be modified, and will allow modification
of the value. Subsequently, the drive will send
only the logic value to the Remote node, with the
use of the Display Logic Value Response
message, when the data changes and at regular
4 second intervals.
