SIPLUS Y-Link for S7-400H Siemens

Область применения



The Y-Link is a transceiver for the transition from a redundant PROFIBUS master system to a single-channel PROFIBUS DP master system. It is used to connect devices with a single PROFIBUS DP interface as switched I/O to S7-400H.

Обзор


  • Bus coupler for transition from a redundant PROFIBUS DP master system to a single-channel PROFIBUS DP master system
  • For connection of devices with only one PROFIBUS DP interface to the redundant PROFIBUS DP master system of the SIMATIC S7-400H

Note:

SIPLUS extreme products are based on SIMATIC standard products. The contents listed here were taken from the respective standard products. SIPLUS extreme specific information was added.

Дизайн



The Y-link comprises:

  • 2 IM 153-2 High Feature Outdoor interface modules
  • 1 Y coupler
  • 1 BM IM/IM bus module
  • 1 BM Y-coupler bus module

Snapped on mounting rails for setup with active bus modules.

Configuration options and limitations

A redundant PROFIBUS DP master system can be extended by means of Y links in the following way:

  • The number of Y links on a redundant DP master system is only limited by the maximum number of stations. The maximum number of connectable slaves depends on the length of the user data and configuration message frames. The total length of each may not exceed 244 bytes (see slave technical data). Generally, the following applies:
    • Max. 64 stations in the lower-level DP master system
    • Max. 236 slots in the lower-level DP master system
  • Y link configuration and user data message frames comprise message frame contents of the lower-level slaves. The maximum frame length is therefore 244 bytes.
  • Direct communication and equidistance not possible in the lower-level master system

Функции



Y link

  • Transmission rates for the redundant master system:
    9.6 Kbit/s to 12 Mbit/s
  • Bumpless switchover of the redundant PROFIBUS DP master system''s active channel.
  • Supports system changes on a SIMATIC S7-400H during operation
  • Diagnostics via LEDs and the user program

Y coupler

  • Transmission rates for the lower-level master system (independent of redundant DP master system):
    187.5 Kbit/s to 12 Mbit/s
  • Electrical isolation between lower-level DP master system and power supply via the coupler
  • IP20 degree of protection

Principle of operation

The Y link maps the lower-level DP master system on the redundant PROFIBUS DP master system as a switched PROFIBUS DP slave .

The Y coupler and the lower-level DP master system form an independent bus system and operate decoupled from the redundant bus system.

The Y link as a DP slave on the redundant DP master system acts as a proxy for the stations on the lower-level DP master system with regard to data.

Configuration

The Y link can be configured with STEP 7 as of Version 5.4. It is not necessary to configure the Y coupler.

When STEP 7 calculates the bus parameters, the stations connected on the lower-level DP master system as well as the Y link itself are taken into account.

Parameter assignment of the DP slaves

The redundant DP master system assigns the parameters for the DP slaves in the lower-level DP master system via the Y link.
