HW Settings
Name | Type, range | SUBID | Default | Description |
---|---|---|---|---|
cfg | string | 98 | 9600/8N1 | cfg=’SPEED/BPS’, where SPEED – baud rate [1200..115200]; B – data length [7,8]; P – presence and type of parity bit [N(No parity),E(Even parity),O(Odd parity)]; S – stop bit length [1, 1.5 or 2]. Example: hw="cfg='9600/8N1'" |
[Protocol] | string | 98 | — | Protocol setting is described by protocol parameter. The following protocols are supported”
Example: hw="cfg='9600/8N1' modbus" |
echo | on; off | 98 | 'off' | For settings check out and testing echo parameter can be used. Module echo-reply can be turned on or off with the help of this parameter. Echo parameter value:
Example: hw="cfg='9600/8N1' echo='off'" |
