Response whatever was recorded.
The default message for discrete channels is: remote channel
<ZZ> normal . The default message for analog channels is
silence (no epilogue).
4 3 ZZ
Function Review both messages for channel ZZ. If ZZ is 00 then all
network ID messages are reviewed.
Response whatever was recorded or the default messages.
F.10 Remote Channel Configuration
Commands in the series “4 5 ZZ," are used for Remote Channels as follows:
K Associate a PLC net address to a Verbatim Remote Channel. This step
tells the Verbatim autodialer where on the PLC network to look for the
point to be monitored.
K Establish the alarm criteria for a Remote Channel. This step tells the
Verbatim autodialer what constitutes an alarm condition in the monitored
PLC point.
K Link a Remote Channel to a phone number or group of phone numbers.
When an alarm occurs in the monitored PLC point only the phone
numbers linked to the Remote Channel will be called. (By default, all
phone numbers will be called.)
Note that you must first assign a net address to a Remote Channel before any
alarm criteria may be configured.
F.10.1 Assigning PLC Net Addresses to Remote Channels
Command “45ZZ” associates a remote channel with a network address and, as
such, is essential for activating an RC. When issued, this command will cause
the Verbatim autodialer to immediately access the specified network address.
Any communications errors at this point will generate the message:
communication error code <diagnostic>. Any command in this section will
support ZZ=00.
If the data type (analog, discrete) of the new address is incompatible with the
existing alarm criteria, then the NOALARM criteria will replace them.
Otherwise, the existing criteria are untouched. The Verbatim will announce this
action. Any links to other RCs are always preserved.
Notes:
See section F.4.2 for an overview of net addresses.
