Communications configuring
System- and communication configuring D7-SYS - SIMADYN D 3-31
Edition 12.2003
3.4 Industrial Ethernet coupling (SINEC H1)
There are three versions for communications via SINEC H1:
• Layer 2
The data are directly transferred via the Ethernet defined in the
SINEC H1 protocol stack.
The transfer is without physical connection and without any
handshaking (acknowledgement). The communication partners are
known as transmitters and receivers. data is packed in telegrams and
transmitted or received. All SIMADYN D communication utilities can
communicate via SINEC H1 in this way.
• Layer 4
The data are transferred via the ISO Transport Layer, defined in the
SINEC H1 protocol stack. The data transfer requires a physical
connection and handshaking (acknowledgement). The communication
partners are designated as transmitter and receiver. Data is packed
into telegrams and transmitted or received. All SIMADYN D
communication utilities can communicate via SINEC H1 in this way.
• Layer 7 (STF), STF=SINEC technological functions
The data to be transferred are defined as variable (object) and are
processed with STF utilities "Read variable", "Write variable". For STF
utilities, there is always a client and a server. The server defines the
variable and responds to utility requests; the client issues the utility
requests. SIMADYN D communication utilities "Process data" and
"Message system" can communicate via SINEC H1 in these ways.
NOTE
When using layer 4 or layer 7:
To configure the bus of the CSH11 coupling module (with integrated
CP1470) the NML configuring tool is required, Order No. 6GK 1740-
0AB00-0BA0!
Each bus node requires the following to allow it to operate on the bus:
• Ethernet address
− is assigned when configuring in the CFC.
• Application associations (layer 7) and data transfer connections
(layer 4 and layer 7)
− defined routes to transfer data between the bus nodes, which are
configured using NML.
• Variables (layer 7) and telegrams (layer 2 and layer 4)
− for SIMADYN D - are assigned when configuring in CFC.
