Appears if:
[r3;Lo]
[r3.Lo] Output 3 Retransmit Low
Scale
Set the low scale for the retrans-
mit output.
-1999.0 to 9999.0
(-1999000 to 9999000)
0 *316, 317
R/W
Output 3 is a process
output (SD_ _ - _ _ _ F
- _ _ _ _ ) and
[Ot`3] is
set to [rmt].
[r3;hi]
[r3.hi] Output 3 Retransmit High
Scale
Set the high scale for the re-
transmit output.
-1999.0 to 9999.0
(-1999000 to 9999000)
500 *318, 319
R/W
Output 3 is a process
output (SD_ _ - _ _ _ F
- _ _ _ _ ) and
[Ot`3] is
set to [rmt].
[r3;CO]
[r3.CO] Output 3 Retransmit Offset
Set the offset value for the re-
transmit output.
-999.0 to 999.0
(-999000 to 999000)
0 *320, 321
R/W
Output 3 is a process
output (SD_ _ - _ _ _ F
- _ _ _ _ ) and
[Ot`3] is
set to [rmt].
[hyS1]
[hyS1] Alarm 1 Hysteresis
Set the hysteresis for an alarm.
This de- termines how far into
the safe region the input needs
to move before the alarm can be
cleared.
0.0 to 999.0
(0000 to 999000)

[Lgc1] Alarm 1 Logic
Select the alarm output condi-
tion in the alarm state.

[`LAt] on (1) [nLAt] (0) 108 R/W [Ot`1] is set to [dE;AL]
or
[Pr;AL].
[SiL1]
[SiL1] Alarm 1 Silencing
Turn alarm silencing on or off.
[`OFF] off (0) no silencing
[``On] on (1) silencing [`OFF] (0) 109 R/W [Ot`1] is set to [dE;AL]
or

[dSP1] Alarm 1 Message
Displays an alarm message
when an alarm is active.
[`OFF] off (0) no message
[``On] on (1) message [``On] (1) 110 R/W [Ot`1] is set to [dE;AL]
or
[Pr;AL].
[hyS2]
[hyS2] Alarm 2 Hysteresis
Set the hysteresis for an alarm.
This determines how far into
the safe region the input needs
to move before the alarm can be
cleared.

Note: Some values will be rounded off to fit in the four-character display. Full values can be read with Modbus. All temperature pa-
rameters through Modbus are in °F, by default. Writing to register 18 will toggle between °F and °C.
* Low register numbers contain the two higher bytes; high register numbers contain the two lower bytes of the four-byte integer.
Decimal precision is implied at three decimal places unless otherwise noted.
