relay stat
This command reports the current relay logic normally “open” or normally
“closed,” if all the relays are set to same state, that is all open or all closed.
The example below shows that the status when all the relays logic is set to
normally “open”.
Send: relay stat
Receive: relay stat open
Note
if individual relays have been assigned different logic then the response
would be a 4-digit hexadecimal string with the least significant byte (LSB)
being relay no 1.
For example:
Receive: relay stat 0x0001 (indicates relay no 1 is set to normally
open logic, all others are normally closed)
Receive:
relay stat 0x0005 (indicates relay no 1 and 3 are set to be
normally open logic, all others are normally closed)
set relay open
set relay open
value
set relay closed
set relay closed
value
These commands set the relay logic to normally open or closed for relay
number
value , where value is the relay between 1 and 16. The example
below sets the relay no 1 logic to normally open.
