Controllable communication modules:
•
Control of the GSM/GPRS modems MD720-3 in the GSM or
GPRS mode. In GPRS mode, simple 128-bit encryption via the
MD720-3 (MSC-VPN tunnel protocol).
•
Operation via SIMATIC NET Ethernet components with high
IPsec security standard (e.g. GPRS router or SCALANCE S)
•
Direct operation on a DSL router by means of MSC tunnel
protocol
•
Use of SCALANCE fiber-optic switches for spanning long
distances
•
Wireless transmission via IWLAN with SCALANCE W over
medium distances
•
Dedicated line modem MD2 for point-to-point, point-to-multi-
point or line connections
•
Wireless devices from various manufacturers, also for private
mobile radio using the time slot method
•
Analog dial-up modem MD3 for the analog telephone network
or point-to-point dedicated lines
Special properties as "control center" TIM
For data transmission via conventional WANs, the TIM 4R-IE has
other, special properties that predetermine its use as a "control
center" TIM:
•
In a dialup network the message "Failure of local node" can be
switched off. If the control desk PC fails or is temporarily shut
down, the control center TIM 4R-IE will not send any failure
message to the stations in the dialup network and therefore
saves transmission costs.
•
One especially useful feature during commissioning is the
possibility that SINAUT stations can be switched on and off on
the control center TIM 4R-IE. This applies not only for stations
that are connected via dedicated line/radio, but also for
stations in the dial-up network. The last status set for each
station is permanently stored on the TIM and is therefore not
lost if the power fails or the TIM is restarted.
•
For GPRS, dedicated lines and mobile networks, the message
"Node faulty" can be suppressed on the TIM 4R-IE for a
programmable period of time. A station failure is then no
longer indicated after x unanswered calls (polls), but only
when a recognized fault still exists after expiry of the
programmed time. This enables the number of failure
messages to be reduced in poor-quality networks and it also
minimizes the additional message frame traffic that must be
processed after each station is restored.
Optional C-PLUG
The most frequent application for the TIM 4R-IE will be its use
as a communication module for the control desk PC or for an
S7-400. The TIM then operates in standalone mode, i.e. without
S7-300 CPU. The option of saving the TIM configuration data on
the MMC card of the CPU, in order to exchange the TIM without
a PG in the event of a fault, no longer applies. The saving of
configuration data on the C-PLUG, which can be optionally
equipped, solves this problem. This means that, even in stand-
alone mode, a replacement of the TIM is possible without PG.

Integration
Connection to IP-based networks
In addition to the two combined RS 232/RS 485 interfaces, the
TIM 4R-IE also has two RJ45 sockets. These are suitable for the
connection of IP-based networks (WAN or LAN). Depending on
the application, various types of data communication equipment
can be connected such as:
•
SCALANCE X switches for Twisted Pair cable or fiber-optic
cables
•
SCALANCE W (IWLAN) and Ethernet radio devices from
various manufacturers
•
SCALANCE M for communication via mobile wireless
networks
•
EGPRS router SCALANCE M874-2 for GPRS communication
and EGPRS (Edge) over mobile wireless networks
•
SCALANCE S for VPN (IPsec)
•
GPRS/GSM modem MD720-3 for GPRS communication via
GSM mobile telephone networks using MSC-VPN tunnel
protocol
•
Directly on a DSL router by means of the MSC-VPN tunnel
protocol integrated in the TIM
•
Broadband systems such as OTN, PCM30
Connection to a conventional WAN
For the connection to a conventional WAN the TIM 4R-IE pro-
vides two floating RS 232/RS 485 interfaces, to which various
data communication devices can be connected, depending on
the application, such as:
•
Dedicated line modem MD2 for point-to-point, point-to-multi-
point or line connections
•
Wireless devices from various manufacturers, also for private
mobile radio using the time slot method
•
Analog dial-up modem MD3 for the analog telephone network
or point-to-point dedicated lines
•
GPRS/GSM modem MD720-3 for access to the mobile
telephone network
