Serial communication between SIMATIC S5 and SIMATIC S7-1500
A SIMATIC S5 station communicates via a serial interface with another station.
In the course of a partial migration, a SIMATIC S5 station will now be replaced by a SIMATIC S7-1500 station.
The example projects/scenarios in this document show the options available to establish a serial communication between the existing SIMATIC S5 controllers and the SIMATIC S7-1500. The following figure schematically shows the most important components and variants of this solution:
The application example describes the following serial communications:
- 3964(R) protocol
- Freeport (S7-1500) or "Open Driver" (SIMATIC S5)
As hardware interfaces, a CP 544 is used on the SIMATIC S5 side and a and a communication module CM PtP RS232 BA on the SIMATIC S7-1500 side.
You receive copy templates that you can quickly use and enhance in your own migration projects. You only need basic knowledge of SIMATIC S5. However, special hardware know-how is not required.
