Interface module for SIMATIC S5/S7 central controllers

￿The interface module for SIMATIC S5/S7 central controllers,

6DS1 333-8AB, is a double-height compact subassembly. The front panel width is 30.48 mm (2 standard slots). The module has 2 base plugs for the I/O bus interface and two serial interfaces for connection of a SIMATIC-S5/S7 central controller.

Mode of operation

The data arriving in parallel via the I/O bus of the automation sys- tem are stored cyclically in the transfer memory (RAM) of the interface module for SIMATIC S5/S7 central controllers. The SIMATIC S5 central controllers can read the transfer memory using fetch messages. The transmitter section of the interface module reads the data from the transfer memory, supplements them into a complete message, and outputs this via the serial interface to the SIMATIC S5/S7 central controller.

Messages transmitted by the SIMATIC S5/S7 central controller are tested for reliability in the receiver section of the interface module, and the data contained in them are stored in the transfer memory. The automation system cyclically reads these data from the transfer memory.
