F-10 Verbatim Owner's Manual
The Verbatim autodialer keeps a count of the threshold violations.
Programming commands are available to announce and reset these counts. It is
also possible to announce the current value of the status code and set the
threshold to any severity level. See section F.16 for details.
F.7.1 Abbreviations and Typographic Conventions
In the following sub-sections, the verbal response expected from the Verbatim
autodialer will be given following the program code that the user is to enter for
each programmable function. This verbal response will be differentiated by
being in italics in the following way: Remote Channel Number TEN, Alarm,
Acknowledged. The following table describes the abbreviations used in the code
listings and elsewhere in this document:
Code Listing Abbreviations
Code Description
ZZ Any two-digit remote channel number, from 01 to 96, depending on the
hardware configuration.
yy Same as above
N An integer from 0 to 65535, or as specifically noted.
net The network ID: 1 to 5
node The node address, as appropriate for a given network.
addr The PLC address, as appropriate for the given PLC. (Details on specific PLCs
and protocols are found in the appendices.)
DN A two-digit code indicating a specific phone number.
V An arbitrary floating point number of the form: 1.23. If 3 or more digits to the
right of the decimal point, V is truncated to the nearest .005.
* Same as ‘point’ key
# Same as ‘minus’ key
F.8 Remote Channel Status, Reading, and
Writing
4 0 ZZ
Function Read alarm status of Remote Channel ZZ. (See code 49402
for Network Alarm Status)
Response remote channel <ZZ> <alarm status>
If ZZ=00 in the following two commands, then the command applies to
the net address specified by the most recent 4500* command. In that
case, the “remote channel ZZ” responses are replaced with the explicit
net address.
4 0 ZZ *
Function directly read PLC address associated with Channel ZZ
