Introduction
Communication via a classic WAN
The response of the TIM on sending the data depends on the
WAN type and the TIM function that is set on the WAN interface:
•
Dedicated line, wireless network;
if the interface is operated in the function "station" or "node
terminal", the TIM waits to be polled by the control center
before it transfers the stored data message frames.
If there are no message frames available, polling is simply
acknowledged.
If operated as a "control center", the TIM sends one of the
message frames saved in the buffer following each completed
poll + response (standard setting). If a larger number of
message frames is to be sent between two polls, this can be
specified when the TIM is configured.
•
Dial-up network;
in "station" or "node terminal" mode, the TIM will initially not be
active in the case of data with "normal" priority. In the case of
data of "high" or "interrupt" priority, the TIM will immediately try
to establish a link to the addressed partner in order to transfer
the data. If data of "normal" priority are also available in the TIM
buffer at this time, these will also be transferred. Data of
"interrupt" priority will always be transferred first. The data of
"high" and "normal" priority will subsequently be transferred in
accordance with the FIFO principle, i.e. regardless of their
respective priority.
If the interface is set to the "control center" function, the TIM will
always try regardless of priority to establish a link to the
addressed partner and to transfer the data.
The SINAUT ST7/ST1 protocol can be used for all WAN types
and TIM functions. The DNP3 protocol only allows use of
dedicated lines and wireless networks in the function "Station".
The operating mode used depends on the type of WAN:
•
Data exchange via dedicated line and wireless network
usually takes place in "Polling" mode. In wireless networks with
SINAUT ST7 protocol, the operating mode "Polling with time
slot method" can be selected if required.
•
On dial-up networks (only with SINAUT ST7/ST1 protocol),
data exchange always takes place in "Spontaneous" mode.
Communication via an IP-based network
For transmission via an IP-based network, a permanent S7 con-
nection via which the partners exchange the data packages is
established in each case between two TIMs or between one TIM
and the control system.
PG communication
PG communication allows all S7 stations connected to the LAN,
e.g. Industrial Ethernet, to be remotely programmed. With the
aid of S7 routing it is possible to use programming device com-
munication across networks.
Cross-network PG communication functions with the
SINAUT ST7 protocol for all classic and IP-based WANs.
Remote programming and remote diagnosis of the stations con-
nected to the WAN (CPUs and TIMs) is therefore possible.
In IP-based DNP3 networks, PG communication does not take
place via the protocol itself, but via a separate PG connection
(TCP/IP connection).
Diagnostics & service
The "SINAUT Diagnostics & Service Tool" provides comprehen-
sive diagnostic functions and tools for commissioning and
troubleshooting, e.g.:
•
Operating status of the TIM
•
Module status of the TIM
•
General diagnostic information
•
Diagnostics buffer of the TIM
•
Status of the connections to local and remote communication
partners (CPUs, TIMs, control systems)
•
TIM frame monitor for recording the frame traffic
•
Disabling and enabling stations in the dedicated line or
wireless network, e.g. during commissioning
TIM modules with Ethernet interface also offer the following:
•
Status and fill level of the send buffer, for each communication
partner separately
•
Diagnostic information regarding TD7onTIM
Configuration
The "SINAUT ES" configuration software is used for configuring
the TIM. Modules from the "SINAUT TD7 module library" must
be used for configuring the SINAUT program in the CPU
(TD7onCPU). Both software packages are part of the SINAUT ES
engineering software. The SINAUT ST7 configuration software
requires that STEP 7 V5.5 with SP2, or higher, is installed.
The configuration data – like the interface functionality, protocol,
addresses of the communication participants, the telephone
numbers of the partner in the dial-up network, etc. – that are
required in each case can be saved in the Flash EPROM on
every TIM or, in the case of the TIM 4R-IE or TIM 4R-IE DNP3,
also on the optional plug-in C-PLUG. On all TIMs with Ethernet
interface, the configuration data can also be stored on the
memory card (MMC) of the CPU when installing in an S7-300
rack or in a C7 control system. The TIM can be replaced without
the need for a programming device if the configuration data is
saved in the CPU or in the C-PLUG.
Approvals
All TIM communication modules have the approvals CE, FM,
ATEX, cUL508 (= UL508, CSA22.2) and cUL HazLoc. The
TIM 3V-IE and TIM 4R-IE modules are also available in a SIPLUS
version for the extended temperature range (-25 ... +70 °C).
