write 1 ... physically stores new setup into
device’s memory, at the end the register
is automatically reset to zero.
R/W
All registers contains 16b number. Communication examples are listed in a separate document
entitled "Description of communication protocols“.
6.2. Protocol compatible with Advantech-ADAM standard
Control units communicate on master-slave principle in half-duplex operation. Only master can
send requests and only addressed device responds. During sending request any of slave devices should
respond. During communication data is transferred in ASCII format (in characters). Each Byte is sent
as two ASCII characters. Device supports communication speed from 1200Bd to 115200Bd,
parameters of communication link are 1 start bit + eight bit data word (LSB first) + 1 stop bit, without
parity.
