Substations for ST7 protocol
The TIM communication module is housed in an S7-300 enclosure and is available in different versions:
TIM 3V-IE/TIM 3V-IE Advanced
The TIM 3V-IE is a SINAUT communications module for the SIMATIC S7-300. It has an RS232 interface to which a matching external modem can be connected for data transfer via a conventional WAN. It additionally possesses an RJ45 interface, which permits communication over IP-based networks. In the case of the TIM 3V-IE, SINAUT communication can be processed alternately via one of the two interfaces, while in the TIM 3V-IE Advanced both interfaces can be operated simultaneously.
TIM 4R / TIM 4RD
The TIM 4R is a SINAUT communication module with flexible application options:
- Suitable for installation in a SIMATIC S7-300 as a communication module
- Also as an independent device (without S7-300 CPU), it can be connected via its MPI to one or more SIMATIC S7-300/-400 and to the control center PC (SINAUT ST7cc or ST7sc).
Apart from its MPI port, the TIM 4R has two RS232/RS485 interfaces for data transmission via conventional WANs. The two WAN networks can be different, for example, dedicated line plus telephone network, and operated independently of one another, but also in a redundant combination.
The TIM 4R is optionally available with an integrated DCF77 radio clock receiver (TIM 4RD). From this module, it is possible to supply the date and time to all nodes in the telecontrol system.
TIM 4R-IE
The TIM 4R-IE has two RS232/RS485 interfaces for data transmission via conventional WANs and additionally two RJ45 interfaces for connection to IP-based networks (WAN or LAN).
This TIM can be used as communication processor in a SIMATIC S7-300, but it is especially suitable as telecontrol module for a SIMATIC S7-400 or control center PC (SINAUT ST7cc or ST7sc). It is then connected without S7-300 CPU as a standalone device via one of the two Ethernet interfaces to the S7-400 or the PC .
The four transmission paths can all be different and operated independently of one another, but also in any redundant combination.
