3.7 Installation of the TIM 3 / TIM 4 as CP in an S7-300
Installation in a rack
With standard and compact CPU modules, the TIM can be inserted into any of the racks 0 to
3 but only in expansion racks 1 to 3 if these racks are connected to the CPU over the IM
360/IM 361 interface modules.
With the C7 control systems, the TIM can be inserted in any of the expansion racks 1 to 3.
These are connected to the C7 device over IM 360/IM 361 interface modules (the IM 360 is
already integrated in the C7 device). With the C7-635 and C7-636 devices, this is also
possible without the IM 361 if no more than four modules including the TIM are connected
externally.
For all S7-300 racks the following applies: All slots designed for SM, FM or CP can also be
used for the TIM.
A bus module connector ships with every TIM. The TIM is connected to the module to its left
by the bus module connector.
If a SINAUT modem of the type MD2, MD3 or MD4 is used, this can be installed on a
separate S7-300 rail or on a 35 mm DIN rail (an adapter is available). To save space, it can
also be installed in a free slot of racks 0 to 3. This modem is connected over the RS-232 port
of the TIM using a standard connecting cable, type 6NH7701-xxx.
NOTICE
Since the modem does not have an S7-300 backplane bus, an S7-300 SM, FM or CP
module that communicates with the CPU over this backplane bus must not be installed to
the right of the modem!
Note
In all of the sample configurations of the S7-300, it is assumed that a 24 V power supply is
available for the CPU, the TIMs and the other modules.
S7-300 with one WAN attachment
When a TIM 3 with integrated modem is installed, an S7-300 has access to a classic WAN,
for example to a dedicated line network or telephone network. The following figure shows
such a simple station configuration.
