Global parameters

Block 6 (DW1001 ... DW1023) of the administration data blocks contains
global parameters. These are parameters that are valid for several blocks.
For details of which global parameters a standard function block uses,
please refer to the description of the individual standard function blocks.

The data words in block 6 must be initialised when the program is started
(OB120) using SB070/SB071 (INIT_MBS).
The abbreviations in brackets {... : ...} at the end of each data word
correspond to the parameters in SB071. The times that are also specified
within the brackets are empirical values, unless stated otherwise.

DW1001

Number of cycles in the contact synchronisation time between
2 N/O contacts or 2 N/C contacts (e.g. E-STOP button, reset
key, etc.)
{CoSy : 50ms}

DW1002

Number of cycles in the feedback loop’s reaction time to a
change in the PSS output connected to the main contactor
{RFbL : 100ms}

DW1003

Number of cycles in the contact switchover time between a N/
O and N/C contact (pushbutton)
{CS_B : 100 ms}

DW1004

Number of cycles in the contact switchover time between a N/
O and N/C contact (relay)
{CS_R: 50 ms}

DW1005

Number of cycles in the machine clock time
{MaCy : max. 30 s in accordance with EN 61496-1 section
A.8.4, 06/98}

DW1006

Number of cycles in the permitted ESPE reaction time
{ESPE : max. 150 ms in accordance with EN 61496-1 section
5.2.4, 06/98}
