5-7 Modular Block System: Burner Management
Input parameter SSNR
MBS standard function blocks have input and output parameters which can
be adapted to suit the respective control configuration. The input
parameter SSNR
(safety subroutine number) is available on all MBS
standard function blocks. It is required to manage the administration data
blocks DB015, DB016 and DB017.
INFORMATION
MBS standard function blocks may differ in terms of the permitted value
range for the SSNR. The following value ranges are possible for the SSNR:
• Value range of input parameter SSNR: 1 ... 200
(byte constant type: KB001 ... KB200)
• Value range of input parameter SSNR: 1 ... 600
(word constant type: KF000001 ... KF000600)
The valid value range for the SSNR of a standard function block is
documented in the standard function block description.
The input parameter SSNR determines the administration data block plus
the 5 data words assigned in the administration data block of the
corresponding safety device (1 DW per block). The administration data
blocks are assigned the following SSNR ranges:
• SSNR 001 ... 200: DB015
• SSNR 201 ... 400: DB016
• SSNR 401 ... 600: DB017
The one data word per block is generated automatically internally (SSNR +
offset).
