Introduction

Introduction
All TIM types can be installed as a CP in an S7-300 device. With the exception of the
TIM 3V-IE, every TIM variant can be operated with several other TIMs in an S7-300 rack.
The TIM 4 or TIM 4R-IE can also be mounted as a standalone device on an S7-300 rail and
then communicates with S7-400 or S7-300 CPU modules and/or a PC control center over its
MPI interface (TIM 4) or over Ethernet (TIM 4R-IE).
Note
Before you install a TIM module on the S7-300 rail, it is advisable to make all the required
settings for operation on all the DIL switches of the TIM. These switches are more accessible
when the module is not installed. If there is a DCF77 radio clock on the TIM, you should also
plug in the DCF77 adapter cable before installing the TIM.
The TIM can be operated both in a horizontal and in a vertical installation.
The following sections describe how to mount the devices as a CP or standalone device.
4.4.3

Installing a TIM module as CP

Note
If you intend to install a SINAUT ST7 MD2, MD3 or MD4 modem to the right of the TIM,
remember that the modem does not have an S7-300 backplane bus. There must therefore
be no S7-300 module that communicates with the CPU over the backplane bus (SM, FM or
CP) installed to the right of the modem.
To connect the TIM and MD2, MD3 or MD4 modem, no bus module connector is required
(nor does this ship with the modem). The connection between TIM and modem is only over
the connecting cable of the type 6NH7701 on the front.
Order of installation
Install a TIM as a CP in an S7-300 rack by following the steps in the order shown below:
1. Turn off the power supply to the CPU.
2. A bus module connector ships with the TIM. Insert this in the backplane connector of the
module to the left of the TIM.
3. If you want to install further modules to the right of the TIM, insert the bus module
connector of the next module into the right backplane connector of the TIM.
4. Place the TIM on the standard rail and push it in towards the bottom.
5. Screw the TIM securely into position.
