I/O Status Registers 5000 - 9399
Bit Information Meaning
15 Communications
failure For inputs, this bit is set (“on”) if no message has been received
from the remote address within the timeout period configured for
this input. The bit is reset ("off") when a message is received.
For outputs, this bit is set (“on”) if transmission to the remote was
unsuccessful after five attempts. The bit is reset ("off") when a
message is transmitted successfully. This bit may also be set if the
Disable Output Transmissions on Comms Fail option is selected -
see the Radio Comms Failure section.
14 Start-up status For inputs, this bit remains set ("on") following start-up until a
message has been received for this input to give an initial input
value.
For outputs, this bit remains set ("on") following start-up until the
105C sends the first radio message for this output to the remote
address.
13 Input / Output
status This bit is set ("on") if this I/O point has been configured as an
input.
12 Active status This bit is set ("on") if the register has been configured as an I/O
point.
11-10 Timer Units This field determines whether the timer counts down every 10
seconds, every minute, or every hour.
Timer Units Timer timebase
00 Every 10 seconds
01 Every minute
10 Every Hour
11 Every Hour
9 - 0 Timer For inputs, the timer value is set to the configured comms fail time
for the input whenever a message has been received for this input.
The timer value will decrease until another message is received.
When the timer value reaches zero, the comms fail status is set. If
the configured comms fail time is zero, then the comms fail status
for this input is never set.
For outputs, the timer value is set to the configured update time for
the output whenever a message is transmitted by the 105C to the
remote address. The timer value decreases. When the timer value
reaches zero, another update message is transmitted to the remote
address. If the configured update time is zero, no update messages
are transmitted for this output.
