Connection to IP-based networks

As well as the combined RS 232/RS 485, the TIM 1531 IRC also has three RJ45 sockets. These are suitable for the connection of IP-based networks (WAN or LAN). Depending on the application, various types of data communication equipment can be connected such as:

• SCALANCE X switches for twisted pair cables or fiber-optic cables
• SCALANCE W (IWLAN) and Ethernet radio devices from various manufacturers
• SCALANCE M for communication via mobile wireless networks and DSL/SHDSL.
• SCALANCE S for VPN (IPsec)
• GPRS/GSM MD720-3 modem for GPRS communication via GSM mobile telephone networks using MSC-VPN tunnel protocol
• Directly on a DSL router by means of MSC-VPN tunnel protocol integrated in the TIM
• Broadband systems such as OTN, PCM30

Connection to a conventional WAN

For the connection to a conventional WAN the TIM 1531 IRC provides a floating RS 232/RS 485 interface, to which various data communication devices can be connected, depending on the application, such as:

• Dedicated line modems for point-to-point, point-to-multipoint or line connections
• Wireless devices from various manufacturers, also for private mobile radio using the time slot method
• Analog dial-up modem for the analog telephone network or point-to-point dedicated lines
• GPRS/GSM MD720-3 modem for access to the mobile network

Configuration examples using TIM 1531 IRC

Use in a node station

In a node station with a SIMATIC S7-1500, the TIM 1531 IRC is connected to the S7-1500 via one of its three Ethernet interfaces and can, for example, exchange data by radio with the subordinate stations via another Ethernet interface with path redundancy.

Redundant transmission paths

Using TIM 1531 IRC, a station can be connected to the control center over redundant paths. The TIM 1531 IRC is used for this purpose both in the station and in the control center. The example shows a combination of dedicated lines and radio as redundant paths. Data transfer takes place normally over the main path and only if it fails over the standby path. When the main path is restored, changeover back to this path is performed automatically.
