Second access:

SI Control Byte2 Data Byte2

16 bit Diagnosis

SI command: Control Byte 2 programs the

operation mode of channels 9 to 16.

Data Byte 2 gives the input information (on

or off) for Channel 9 to 16.

SO diagnosis: Diagnosis information of

channel 1 to 8 or 9 to 16, depending on the

SI control word before.

SI Control Byte2 Data Byte2

DIAG_2 (Ch. 9 to 16)

SI command: Control Byte 2 programs the

operation mode of Channels 9 to 16.

Data Byte 2 gives the input information (on

or off) for Channel 9 to 16.

SO diagnosis: 16 bit diagnosis information

(two bit per channel) of channels 9 to 16

Detailed Description

As mentioned above, the serial input information consist of a control byte and a data byte. Via

the control byte, the specific mode of the device is programmable.

Control Byte

Data Byte

Ten specific control words are recognised, having the following functions:

No. SI Contol and Data Byte

Function

1 LLLL LLLL XXXX XXXX 'Full Diagnosis' (two bits per channel) performed for

channels 1 to 8. No change to output states.

2 HHLL LLLL XXXX XXXX State of the eight parallel inputs and '1-bit Diagnosis'

for channel 1 to 8 is provided

3 HLHL LLLL XXXX XXXX Echo-function of SPI; SI direct connected to SO

4 LLHH LLLL DDDDDDDD IN1...4 and serial data bits 'OR'ed. 'Full Diagnosis' per-

formed for channels 1 to 8.

5 HHHH LLLL DDDDDDDD IN1...4 and serial data bits 'AND'ed. 'Full Diagnosis'

performed for channels 1 to 8.

6 LLLL HHHH XXXX XXXX 'Full Diagnosis' (two bits per channel) performed for

channels 9 to 16. No change to output states.

7 HHLL HHHH XXXX XXXX State of the eight parallel inputs and '1-bit Diagnosis'

for channel 9 to 16 is provided.

8 HLHL HHHH XXXX XXXX Echo-function of SPI; SI direct connected to SO

9 LLHH HHHH DDDDDDDD IN9...12 and serial data bits 'OR'ed. 'Full Diagnosis'

performed for channels 9 to 16.

10 HHHH HHHH DDDDDDDD IN9...12 and serial data bits 'AND'ed. 'Full Diagnosis'

performed for channels 9 to 16.

Note: Control Byte: Channel Selection via Bit 0 to 3

Bits 0 to 3 = L Channels 1 to 8 selected

Bits 0 to 3 = H Channels 9 to 16 selected

Data byte: 'X' means 'don't care', because this data bits will be ignored

'D' represents the data bits, either being H (= ON) or L (= OFF)
