All 7 layers of the ISO reference model are implemented on the module. The programmable controller is extensively relieved of communications tasks and protocol handling. The interface to the user program is formed by standard function blocks (data handling blocks).\par Layers 1 to 4 correspond to international standards. SINEC AP is used for Layers 5 to 7a; the technological functions (TF) are available for Layer 7b.\par\plain\f0\fs18\b PG/OP communication\plain\f0\fs18\par Remote configuring of the CP 1430 TF and remote programming of the CPU over the network are possible.\par\plain\f0\fs18\b S5-compatible communication (SEND/RECEIVE and FETCH/WRITE)\plain\f0\fs18\par Simple data exchange between SIMATIC S5 PLCs by means of data handling blocks (e.g. SEND/RECEIVE) and with S7/PCs. Both static and dynamic connections are supported.\par\plain\f0\fs18\b TF interface\plain\f0\fs18\par MMS-compatible user services with TF (layer 7):\par\pard\fi-284\li284\sb60\tx284\plain\f1\fs18 \'b7\plain\f0\fs18\tab variable services;\par\plain\f1\fs18 \'b7\plain\f0\fs18\tab domain services;\par\plain\f1\fs18 \'b7\plain\f0\fs18\tab program invocation services;\par\plain\f1\fs18 \'b7\plain\f0\fs18\tab general services for virtual devices;\par\plain\f1\fs18 \'b7\plain\f0\fs18\tab services of the TF link management.\par\pard\sb100\plain\f0\fs18\b Real-time functions:\plain\f0\fs18\par Network-wide real-time synchronization, e.g. to provide messages with a time stamp.
