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

1 2 ... 70 71 72 73 74 75 76 77 78 79 80 ... 204 205
