Modems
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.

Modems
B) On-Line Configuration
Allows the Administrator to make changes to
the Modem special command set over the
telephone line.

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.
