Siemens Simatic S7 Driver
Overview
The driver implements Ethernet S7comm (S7 Communication) - Siemens proprietary protocol that runs between programmable logic controllers (PLCs). It is used for PLC programming, exchanging data between PLCs, accessing PLC data from SCADA (supervisory control and data acquisition) systems and diagnostic purposes.
The protocol is also used on top of other physical/network layers, like RS-485 with MPI (Multi-Point-Interface) or Profibus. However, Ethernet has several advantages against Profibus/Mpi:
- It’s faster, CP 1543-1 (for the newborn S71500) has a bandwidth of 1000 Mbps
- It’s simpler to troubleshoot, in 50% of cases a “ping” is good enough to solve your problems
- It’s cheaper, you don’t need special adapter to communicate
Key features
- Works with Siemens S7 Ethernet PLCs
- Enables input/output/timer/counter read and write
- Enables DB (Data Block) read and write
- Provides PLC status
- Allows to START/STOP PLC
- Supports time sync
Niagara-powered device with software v3.8 (AX), v4.1 (N4) or later, including Jace8000, Supervisor or their OEM versions
Jace 8000 250/1000/unlimited points OR Supervisor 500/Extra 500 points
