This tutorial demonstrates how to use MSTR Block in Telepace Studio For SCADAPack (Schneider Electric). We will be performing this demonstration on a SCADAPack 357. The same logic can be used for SCADAPack 350 as well. As a matter of fact in any Schneider Electric SCADAPack.
Summary of the logic
We will be using a PULS (Pulse Seconds) block to trigger the poll. We will be polling every 2.5 seconds. Note that the PULS element controls a square wave digital signal.
We will be using the MSTR element, to exchange data with another controller using the Modbus RTU. Note that MSTR element can also be used to communicate using DF1 communication protocols.
