Here we present S5-software that implements RK512.

RK512-
Interpreter

S5-Software

Simatic S5 - Runtimesoftware


There are several systems in the S5 family which do not support RK512 without help. Below we give a list of devices for which we provide a native RK512 interpreter; it works as slave and allows access to data blocks.
In each case a device with a second serial line is needed.

rk512_095 RK512 interpreter for S5-95U with second serial interface.
rk512_944 RK512 interpreter for S5-115U CPU 944B with second serial interface and operating system module for 3964R.
rk512_945 RK512 interpreter for S5-115U CPU 945.
 
All products implement a subset of RK512 (Exchange of data blocks DB) and consist of two Function blocks (FB) and three data blocks (DB) with the following purposes:
  • 1. DB administration data.
  • 2. DB buffer for outgoing data.
  • 3. DB buffer for incoming data.
  • 1. FB initialization (must be called in OB21 and OB22).
  • 2. FB the RK512 interpreter (called in OB1).
The numbering of these blocks can be chosen freely; DB numbers are parameters to the function block calls. All these S5 programs are very easy to install:
Copy them into your S5 application; then call the init FB from OB21 and OB22; last place a call to the interpreter FB in OB1; done !!!

Features:

  • we use 3964R because of the additional block check character
  • we support Folgetelegramme
  • very small encrease of the plc's cycle time
  • small usage of plc memory
