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 output
s 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.
