ADLINK PCI-7442 - Manual (Page 74)

62 Register Format
You do not need to set any register for the WDTSafety DO Read-
Back Start. You only need to send out the address (BASE+0x28h)
in Read mode before reading all 128 channel output safety data.
When the DO bank receives the Start command, the flash memory
read procedure starts after 100 ms. You can check if the proce-
dure is finished by get nAction_Ready flag status.
Address R/W Value Mapping (MSB----LSB)
BASE + 0x26h W IDO[15…....0]
BASE + 0x28h W IDO[31…..16]
BASE + 0x2Ah W IDO[47…..32]
BASE + 0x2Ch W IDO[63…..48]
BASE + 0x2Eh W IDO[79…..64]
BASE + 0x30h W IDO[95…..80]
