Parameter Data Structure
SPC3 evaluates the first seven data bytes (without user prm data), or the first
eight data bytes (with user prm data). The first seven bytes are specified
according to the standard. The eighth byte is used for SPC3-specific
communications. The additional bytes are available to the application.

Bit Name Significance Default State
0 Dis_Startbit The start bit monitoring in the receiver
is switched off with this bit Dis_Startbit = 1,
That is, start bit monitoring is switched off.
1 Dis_Stopbit Stop bit monitoring in the receiver is
switched off with this bit Dis_Stopbit = 0
That is, stop bit monitoring is not switched
off.
2 WD_Base This bit specifies the time base used
to clock the watchdog.
WD_Base = 0: time base 10 ms
WD_Base = 1: time base 1 ms WD_Base = 0
That is, the time base is 10 ms.

5 Publisher_Enable DXB-publisher-functionality of the
SPC3 is activated with this bit Publisher_Enable = 0, DXB-request-
telegrams are ignored;
Publisher_Enable = 1, DXB-request-
telegramme are processed
6 to 7 Res To be parameterized with 0 0
