The individual data characters represent the status of the individual system alarms. An
ASCII "0" indicates that the alarm is inactive and an ASCII "1" indicates that the alarm is
active. The alarm definitions are listed below.
d1 = PRDHH (product level high high)
d2 = PRDHI (product level high)
d3 = PRDLO (product level low)
d4 = PRDLL (product level low low)
d5 = INTHI (interface level high)
d6 = INTLO (interface low level)
d7 = TMPHI (temperature high)
d8 = TMPLO (temperature low)
d9 = GAUGE level error
d10 = STI error
d11 = mass stab error
d12 = RTD average error
d13 = GAUGE temperature error
d14 = MASHI (mass stabilization high)
d15 = MASLO (mass stabilization low)
d16 = not defined (always ASCII "0")
Register 13 output example from Level Plus monitor at communication address E, Tank
5, LVLLO and INTHI alarms active, all others inactive.
<STX>E513:0010100000000000<ETX>
Register 14 general format (Read tank gauge data)
<STX>attr:dddddd:dddddd:dddddd:dddddd:dddddd:dddddd:dddddd:dddddd:dddddddd:dd
dddddd<ETX>cc
<STX> = ASCII start of text character (02 Hex)
a = Level Plus communication address
t = tank number
rr = register number
: = ASCII colon field delimiter (3A Hex)
d = data (fixed at 8 fields of 6 characters and 2 fields of 8 characters)
field 1 = product level
field 2 = interface level
field 3 = average temperature
field 4 = RTD 1 temperature
field 5 = RTD 2 temperature
field 6 = RTD 3 temperature
field 7 = RTD 4 temperature
field 8 = RTD 5 temperature
field 9 = GOVT
field 10 = NSVP
<ETX> = ASCII end of text character (03 Hex)
cc = optional 2 byte checksum (if enabled)
NOTE
d1 is the first character after colon delimiter character.
