Condensed Format

The condensed format consists of the flags byte and the module key

parameter for each of the eight slots. This parameter dictates which

I/O module must be installed. If at any time the actual module ID

does not match this module key, the slot will be considered in fault

and the following occurs:

• STATUS LED flashes red/off

• an error bit in the poll response data is set

• a diagnostic bit in the Ext_Diag_Data field returned in the Read

DP–Slave Diagnostic Information message response is set

All eight slots must be configured. The size for this format is always

17 bytes (including the flags byte). The condensed format structure

must be repeated for each of the eight slots.
