Properties of the TIM
Application
The TIM 1531 IRC is a telecontrol communications module for the following SIMATIC
automation systems:
● S7-300
● S7-400
● S7-1500
The TIM serves as the connection of the SIMATIC stations via public or private
infrastructures to a telecontrol master station. Precisely one local CPU is assigned to the
TIM.
As a standalone device it is not dependent on the S7 device family or rack type of the
assigned CPU.
For the telecontrol communication the TIM uses the "SINAUT ST7“ protocol.
Due to the capability of the TIM to establish redundant transmission paths between stations
and to the master station and the option of storing process values the communication has a
high degree of reliability.
Master station types
As the connection partner of the TIM in a telecontrol master station, the following computer
assisted applications are supported:
● SINAUT ST7cc
● SINAUT ST7sc
● SIMATIC WinCC OA
If no master station PC is used, the TIM can be used as a master station. For visualization,
for example, an HMI panel can be used via the CPU.
