KAL = Keep Alive or heartbeat of the 1-Wire Controller / 1-Wire Gateway
With the Config-Tool 3 you can comfortably set all settings for the KAL function and save them permanently.
9.1.1.
Keep Alive Send, KAL SEND ON/OFF (KAL = Keep Alive or heartbeat)
At a fixed time interval, the 1-Wire Controller / 1-Wire Gateway outputs a so-called "Keep Alive" (KAL) or
"Heartbeat" message. This is to signal the correct function of the 1-Wire Controller / 1-Wire Gateway and the data
transmission path to the higher-level system.
The time interval of the KAL message can be changed (KALSENDTIME) or completely deactivated (KALSEND).
Selectable states: ON = 1 / OFF = 0, delivery state: ON = 1
Data output:
1_EVT|time
=> Controller no._event | time
1_KAL|1
=> Controller no._data record |1
Command:
SET,SYS,KALSEND,0 or 1
9.1.2.
Data and KAL (heartbeat)
If the "KAL SEND" function has been activated, ON, a "sign of life" in the following form is sent in a fixed rhythm.
This is also sent if the 1-Wire Controller or 1-Wire Gateway is in run 0 mode, i.e. no data output is enabled.
1_EVT|11:50:20 => 1-Wire Controller / 1-Wire Gateway no. Event|time (H:M:S)
1_KAL|1
9.1.3.
KAL SEND TIME 60 - 240 (Keep Alive Send Time)
The time interval of the KAL message can be changed.
Selectable range: 60 - 240 seconds
Factory setting: 60 seconds
Command
: SET,SYS,KALSENDTIME,60 - 240
9.1.4.
Keep Alive Receive, KAL REC ON/OFF (Keep Alive Receive)
The 1-Wire Controller / 1-Wire Gateway expects in a fixed time interval, default 65 seconds, a
"Keep Alive" message from the higher-level system (PC, PLC, ...).
If the KAL message fails to appear, the Data LED flashes rapidly in a fixed cycle and the assigned switching
output of a 1-Wire switching module is activated.
The time interval of the KAL message can be changed (KALRECTIME) or completely deactivated (KALREC).
Selectable states: ON = 1 / OFF = 0, delivery state: OFF = 0
Command
: SET,SYS,KALREC,0 or 1
9.1.5.
KAL REC TIME 60 - 240 (Alive Receive Time)
The time interval of the KAL message from the higher-level system (PC, PLC, ...) can be changed
(KALRECTIME).
Selectable range: 60 - 240 seconds, factory setting: 65 seconds
Command
: SET,SYS,KALRECTIME,60 - 240
