Remote Access Service (Modem)
|
Remote access dial-in kit provide solutions for connecting to a programmable logic controller and / or network of processors over a modem dial-up connection.
|
|
|
The
kit includes additional ports to allow you to access the PLC, locally,
without disconnecting or reconfiguring the access kit once installed.
This
type of setup offers you the opportunity to have a qualified automation
programmer connect, monitor processes, collect data, and make
program changes from an off-site location.
Service
package online minutes are sold for this type of service, and are available
at a reduced cost compared to the standard on-site service rates. Furthermore
there are no expenses billed such as airfare, travel time, car rental
and hotel.
Since
there are such a variety of PLCs and configurations out in the field, Contact Us to obtain a custom-made package that will suit your
needs.

PLC Supported:
• Allen Bradley SLC-500 family, Allen Bradley PLC-5 family, Allen Bradley Micrologix |
Due
to a wide variety of Allen-Bradley PLC configurations, a system
analysis must be conducted to determine what type of modem kit will
be quoted.
The
Following Information is Required:
-
Type
of processor (SLC 5/01, 5/02, 5/03, Micrologix, PLC-5,
etc)
-
Available
ports (Channel
0, Channel 1, etc)
-
Devices or peripherals that are permanently connected to any
port (PanelView,
RediPanel, Bar Code Scanner, etc)
-
Rack
size (7-slot,
10-slot, etc) and if there are any free slots available.
-
Existing PLC network at
your location (DH-485, DH+, Ethernet, etc)
-
If Multiple PLCs are to be setup on a network where they can be accessed through one modem, the distance between
each processor is required to determine the correct cable length
and if any signal boosters or relay stations will be required.
(Certain PLC configurations may not allow a simultaneous
network and modem setup.)
Note: Preferably, a dedicated telephone line must be routed to the electrical
enclosure that will house the modem kit. If an existing active telephone
line is to be used, it must not be interrupted during a live connection
to the PLC or network. |
