         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.

         What is an Intelligent Modem?
         It has…
         an on-board powerful micro-computer.
         a dedicated resident programme and
         operating system.
         a special extended command set.
         a number of PLC Drivers.

         What is an Intelligent Modem?
         It…
         does not require a PC or Laptop connected.
         does not require complex and lengthy PLC
         programming.
         automatically monitors and converts data
         before transferring to the PLC.
         can be programmed to perform complex
         tasks.

         Applications range from On-Line
         maintenance to automatic failure reporting.
         Any Remote Telemetry application, requiring
         control and monitoring of data between out-
         stations.
On-line maintenance                       Modems
Applications




On-line maintenance only requires a PC, DESK-
MODEM 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.

Dial On Demand
Application




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 on-
line.

Wide Area Telemetry
Application




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.
