Command

set communications
watchdog timer
40
set host port time-
out
57020114-00E
Description
Sets the communications watchdog timer
value in ms. This timer denotes the amount of
time that can pass without a successful
communication. If this timer value is
exceeded, the unit will turn output off if the
output is on.
Each AE Bus communications interface has
its own unique watchdog timer. To set the
watchdog timer value for a given port (for
example, the Host port), send this command
from that port. You can set up any
combination of enable, disable, or time-out
values among the interfaces. A value of 0
disables the watchdog timer.
This parameter is volatile and defaults to 0 ms
each time you turn the unit on. The maximum
value is 65535 ms. The unit stores the
watchdog timer value internally in 10 ms
increments, and truncates any fractional
remainder. The unit accepts a value from 1 to
9, but stores it as a time‑out period of 10 ms.
Send 3 data bytes:
• Byte 0 = Enable/disable timer
• Bytes 1 and 2 = Timer value in ms. Valid
values are 1 to 65535 ms
Command 139 reports this value
Sets the amount of time that the generator
waits between bytes from the host before
resetting and waiting for a new packet. Each
AE Bus communications interface has its
own unique host port time-out. To set the host
port time-out value for a given port (for
example, the Host port), send this command
from that port.
Send 2 data bytes (16-bit value) representing
units of 10 ms for the time-out value. The
valid range of values is from 2 to 500 (20 ms
to 5.0 s). The default value is 750 ms.
Command 140 reports this value.
