Modems and how they work!
MODEM is an acronym for
MODulator/DEModulator.
Developed for transmitting and receiving data
over the standard telephone lines.
Data rates up to 56.6K baud.
Automatic speed detection, Data
compression, etc.

Where can they be applied?
Applications range from On-Line
maintenance to automatic failure reporting.
Any Remote Telemetry application, requiring
control and monitoring of data between outstations.
On-line maintenance
Applications
Modems
On-line maintenance only requires a PC, DESKMODEM and A2S/DIN modem connected to the remote
PLC.
When on line the PLC or HMI can be monitored or
reprogrammed using the normal software.
The ASVD allows full voice communication at the
same time.

What are the unique features?
a) Two levels of password protection.
b) On-Line Configuration (OLC).
c) Dial On Demand (DOD).
d) Stores Telephone Numbers and Messages.
e) Wide Area Telemetry (WAT).
f) Automatic Simultaneous Voice & Data
(ASVD).
g) Plug and Play.

Modems
A) Password Protection
USER LEVEL
 to protect unauthorised dial-in.
ADMINISTRATOR LEVEL
 for On-Line configuration.
It has
Modems
B) On-Line Configuration
Allows the Administrator to make changes to
the Modem special command set over the
telephone line.
It has
Modems
C) Dial On Demand (DOD)
On request from the PLC...
one or more telephone numbers are auto
dialled.
messages or data is sent after connection.
after data transfer the Modem can stay online or hang-up.
Dial On Demand
Application
Modems
The PLC sets up Telephone numbers and fixed
Message addresses or selected data, then requests an
DOD.
Connection is made and the selected message(s) are
transmitted to a PC before disconnecting or staying online.
It has
Modems
D) Wide Area Telemetry (WAT)
Full data communication between PLC’s.
Automatic reading and writing from or to user
designated PLC memory.
Remote Input and Output forcing.
On-Line monitoring feature.
Wide Area Telemetry
Application
Modems
The local PLC sets a strategy to switch on an output,
then continuously monitor data registers in the remote
FX PLC.
The PLC requests DOD and when connection is
established data transmission takes place until an
Operator commands the PLC to hang-up.
