DW0000 (DB015)
If parameters for a standard function block’s input parameter
SSNR are not within the permitted range, DW0000 of DB015
will contain the incorrect SSNR parameter. The standard
function block will not be enabled (output parameter FG/
ENBL= 0).
If the SSNR=0, DW0000 of DB015 will contain the decimal
value -1 or KH FFFF.
1st data block (DB015/DB016/DB017):
DW 0001 ... DW0200 Bits for hardware and operator errors
The significance of the individual bits can be found in the
description for the relevant standard function block (see
section entitled “Fault diagnostics”).
If a data word contains the value 0, no error has been found
2nd data block ... 5th data block (DB015/DB016/DB017):
DW0201 ... DW1000
Data blocks 2 ... 5 are used for internal block data.
6th data block (DB015/DB016/DB017)
DW1001 ... DW1023
Data block 6 contains the global parameters (see section
entitled “Global parameters”).
