6.
In the
Read Delay
field, enter a value between 0 and 6000. This number
specifies (in 10ms “ticks”) how frequently the Cobalt will poll the PLC for the
presence of new data. (Note: a value of 6000 = 60 seconds; zero = disable).
7.
In the column labeled “
Enable Node,
” place a check in the box for
Node 01.
Other Nodes listed on this page are not supported by the Cobalt –IND.
8. Write Size:
Enter a value between 1 and 100 (or 0 to disable) for the
Write Size.
The Write Size represents the maximum number of 2-byte “words” that the
Cobalt will attempt to write to PLC memory during a single write cycle. (Note: to
accommodate message handshaking overhead, the actual data size required by
the PLC is three words larger than the value specified in this field).
9. Write Tag Name:
For ControlLogix systems, specify a
Write Tag Name
that is
40 characters or less (for example EMS_WRITE1, for Node 01). The Write Tag
Name is a user defined description or title for the area of memory in the PLC
where host-bound data will be written for the Cobalt. (Note: the Write Tag Name
is not to be confused with writing to an RFID transponder, which is often referred
to as “writing to a tag”).
OR
Write Tag Name: For PLC5E, SLC5/05 and MicroLogix systems, enter the PCCC
File Number and Offset (for example N7:0) in the Write Tag Name field. Together
these values identify the location in the PLC’s Status File where host-bound data will
be written for the Cobalt.
10. Read Size:
Enter a value between 1 and 100 (or 0 to disable) for the
Read Size.
The Read Size represents the maximum number of 2-byte “words” that the
Cobalt will attempt to retrieve from PLC memory during a single read cycle.
(Note: to accommodate message handshaking overhead, the actual data size
required by the PLC is three words larger than the value specified in this field).
11. Read Tag Name:
For ControlLogix systems, specify a
Read Tag Name
that is
40 characters or less (for example EMS_READ1, for Node 01). The Read Tag
Name is a user defined description or title for the area of memory in the PLC
from which the Cobalt will retrieve data.
OR
Read Tag Name: For PLC5E, SLC5/05 and MicroLogix systems enter the
PCCC File Number and Offset in the Read Tag Name field. Together these
values indicate the location in the PLC’s Status File from which the Cobalt
will retrieve data.
12.
After entering the proper information for Node 01, click the
Save Settings
button
located at the bottom of the page.
The OnDemand Status Page will be displayed.
