Mounting versions

Mounting versions
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 4R-IE can also be installed as a stand-alone device on an S7-300 mounting rail
(stand-alone device) and then communicates via Ethernet (TIM 4R-IE) with S7-400 or
S7-300 CPU modules and/or a PC control station.
The following sections describe how to mount the devices as a CP or standalone device.
4.2.4

Installing the TIM as a CP

Note
Slots
If a modem is to be installed to the right of the TIM, note that the modem does not have an
S7-300 backplane bus. No S7-300 SM, FM or CP that communicates with the CPU over the
backplane bus should be installed to the right of the modem.
Note
Only one TIM 3V-IE per rack
Only one single TIM 3V-IE may be installed per S7-300. This means that TIM modules of
other types cannot be added either.
Order of installation
To install a TIM as a CP in an S7-300 rack, follow these steps:
1. Turn off the power supply to the CPU.
2. Plug the bus connector, which is included with the TIM, into the rear panel connector to
the left of the TIM.
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.
3. Place the TIM on the standard rail and push it in towards the bottom.
4. Screw the TIM securely into position.
