Sinec-L1

SINEC-L1 is a local network for connection of up to 30 automation components, such as, for example, SIMATIC S5. SINEC-L1-bus is the first fieldbus protocol developed by Siemens. It is perfectly suited for non time-critical control transactions and works according to the master-slave principle.

The driver has the following characteristics: support of up to 30 stations, emergency messages, broadcast, direct traffic from slave to slave, collective READ-function, arbitrarily configurable alarm and polling list, list of all failed slaves available in master operation mode, protocol timeouts may be parameterized arbitrarily, PG-operation possible.
