Ring Order Communications Method
The Ring Order Method has been developed to allow MACRO Devices to be set up with software. Since
the Geo MACRO drive has no hardware switches (SW1 and SW2) to activate nodes and assign it to a
master, the ring order method is necessary. The Turbo Setup program can do this automatically for you;
thi section tells you how to do it manually.
Factory default state for the I-Variables to the Turbo Ultralite (
$$$*** ) and that firmware version 1.939
or above are necessary. In addition, the Geo MACRO drive should have version 1.004 and above
firmware.
1. To initiate the Ring Order Method, start with the new hardware and then enable the MACRO ASCII
Communication Mode by typing
MACSTA255
in the terminal window. At this point, the Software
Interface will seek the first device that has not been setup (i.e. MI11=0). Once communicating with
the device, activate the nodes with MI996 and set up any critical MI-variables that need to be set for
the application. Upon completion of these MI-variable settings, assign a Station Number to the
device with the
STN=n
command where n can be set from 1 to 254. As soon a station number is
assigned to the device, the system will look for the next device that has not been set up (MI11=0). If
assigning a MACRO device as Station Number 20, type
STN=20
in the terminal window and MI11
will be set to 20.
•
If a Macro I/O error is received, make sure I6840, I6841 and I79 are set correctly. Also, make
sure that the unit has not been already assigned a station number.
•
If the Station has been assigned a Station number already, there are two options:
a) Find out the station number n by typing the
STN
command and enter
MACSTA<n>
, where n is
the station number, to initiate MACRO ASCII communication with the Station.
b) Reset the station number of all the stations by entering
MACSTA0
and then
STN=0
. Exit
MACRO ASCII communications by typing
<Control-T>
(^T) . Then enter
MACSTA255
to access the first Station. Now assign it a Station number by entering
STN=n
where n is the
Station number. Enter
(^T)
to exit MACRO ASCII Communications. Enter
MACSTA255
again to access the next station and repeat this process until a MACRO I/O error is received
stating that there are no further unassigned stations.
2. Enter
MACSTA<n>
where n is the Station number. Enter
I996=$F4004
. (Binds to Ring Controller
0 and Node2)
3. Enter
^T
. (Control-T terminates MACRO ASCII Communications.)
4. Enter
MSCLRF2
. (Clears any faults at Node 2.)
5. Enter
I6841= $0FC004
. (Enable Node 2.)
Issue the
SAVE
and
MSSAVE{node}
commands to save the parameters in memory
