The PROFIBUS-DP option enables the KS 94 to be connected to PROFIBUS-DP networks. This allows de-centralized and independent industrial and process controllers to be integrated into PLC or PC systems. The PLC/IPC transfers set-points and control information to the KS 94, and polls process values cyclically. All control functions and the associated scaling and monitoring tasks are executed independently. This ensures high process safety together with short times for engineering and commissioning.
The document describes the PMA KS 94/DP, an advanced decentralized I/O option for the KS 94 controller. It enables cyclic transmission of up to 16 input and 16 output values via PROFIBUS-DP as a slave device. The system allows independent execution of control functions, scaling, and monitoring tasks, ensuring high process safety with short engineering times.
| Cyclic transmission capacity | up to 16 input and 16 output values |
