Parameter
Data type
Description
Execute
Bool On the rising edge (0 > 1), data at the
inputs of the block is written to
PSU/CNX.
HW_Ident_Head
WORD Start address of the entire main module
Cyclic_IO_IN_output_add
WORD
Cyclic input address of the output
Cyclic_IO_OUT_output_add
WORD
Cyclic output address of the output
Output_Number
INT
Number of the output
Output_In_Parameter
UDT_Output_PSU_IN_V2
UDT for output settings
Note
Output_Number parameter
Irrespective of the type of the main module connected, output numbering of CNX8600 4X is
5 to 20. For main modules with 4 outputs, for example: PSU8600 24 V/40
A/4x10 A:
1 to 4 + CNX8600 24 V/4x10 A: 5 to 20 and for main modules with 1 output, for example:
PSU8600 24 V/40 A:1 + CNX8600 24 V/4x10 A: 5 to 20.
The output numbering of CNX8600 8X is 5 to 36. For main modules with 4 outputs, for
example: PSU8600 24 V/
40 A/4x10 A: 1 to 4 + CNX8600 24V/8x2.5 A: 5 to 36 and for main
modules with 1 output, for example: PSU8600 24 V/40 A:1 + CNX8600 24 V/8x2.5 A: 5 to 36
