Return to the AC500 Control Builder by clicking on the
the bottom of the screen.
The AC500 Control Builder software is opened again and the fieldbus variables are automatically
transferred to the Global Variables list of the programming software.
Open the Global Variables in the "Resources" tab. Double click on Slot 1 <R> . The previously
configured variables are displayed and available in the programming software.
Testing the system
In order to test the system, we are going to create a small user program according to the procedure used
in the Getting Started example. We are using the ST programming language (structured text). The
program should read an input of the decentralized station (DC505-FBP) and output the value to the
DC532 device located next to the CPU. The output byte %QB0 at DC532 (located next to the CPU) is
named with the symbolic name by_AC500_DC532_Out16_23.
The program looks as follows:
The input byte with the variable name byDps1_S500_DC505_In0_7 (signals I0 to I7 at DC505) is read
and applied to the output byte by_AC500_DC532_Out16_23 (signals C16 to 23 at DC532).
