1.5 Setting TIM module parameters

System Manual, 07/2009, C79000-G8976-C222-07

Both TIMs synchronize the stations connected over a dedicated line or dial-up network by

synchronizing the TIMs in the stations that, in turn, supply their own CPU. In these

networks, you do not need to make settings for the TIMs. These TIMs obtain their

parameters from the time parameter settings made centrally for the particular SINAUT

network (dedicated line or dial-up network) refer to the section: Setting parameters for

SINAUT networks, Time Services tab).

● Station1, TIM 32

Time synchronization on the S7-300 backplane bus must be enabled for this TIM; in other

words, the TIM then supplies the S7-300 CPU with the current time over the backplane

bus. An interval of 1 minute is recommended.

Note

If a TIM synchronizes an S7-300 CPU over the backplane bus, no synchronization

settings are necessary for the S7-300 CPU in HW Config. The SINAUT software on the

CPU (TD7onCPU, FC TimeTask) handles the synchronization by using the

synchronization message of the TIM to set the CPU clock.

● Station 2, TIM 3V-IE

Here, there are two situations to be taken into account:

– A SINAUT program (TD7onCPU) is running on the CPU:

You set the time synchronization on the S7-300 backplane for the TIM.

– The SINAUT program is configured on the TIM 3V-IE (TD7onTIM):

You do not need to enable time synchronization on the TIM.

Although there is no SINAUT program on the CPU, the CPU can nevertheless by

supplied with the time of day when necessary. In this case, the TIM supplies the time

data to its inputs. This is explained in detail elsewhere (refer to the

section: Synchronization of the CPU time with TD7onTIM).

● TIM Station 3

This TIM handles the SINAUT communication for the S7-400 "Station 3". Here, you will

need to enable time synchronization on the relevant Ethernet interface of the TIM as

master. An interval of 1 minute is recommended.

● Station 3

No settings need to be made for the S7-400 CPU nor for the CP 443 in HW Config. The

SINAUT software on the CPU (TD7onCPU, FC TimeTask) handles the synchronization

by using the synchronization message of the TIM to set the CPU clock.

The next figure shows a further excerpt from the sample project which will be used to explain

further details on synchronization, particularly in an Ethernet network.
