ASIC/1-8655 Tables

Table Messages
The data in the ASIC/1 product family is organized into standard tables. Each table entry
represents one byte of data. Communicating software, supplied by ASI Controls uses the
data in each of these tables to organize, display and modify the parameters you see on your screen.
Some parameters are larger than the 8 bits of a single byte.  In those cases, you will see two adjacent
entries with the added description: ‘hi byte’ and ‘lo byte’.  In the ASI Controls communications
strategy, the ‘hi byte’ always precedes the ‘lo byte’.  When assembled together, these two 8 bit bytes
become a 16 bit ‘word’.  There will also be a ‘Default’ value specified in many cases.  This is the value
given the parameter when shipped from the factory.  It does NOT mean that it is the value the user may
wish to operate his building.

Table 7, Non-volatile Daily Event Schedules

Each ASIC/1 contains a time of day and event schedule. The day is divided into 96
periods of 15 minutes. At midnight, the clock rolls over to period 0, of the next day. An
event time of zero, indicates that the schedule is not used. Also the controller does not
look to the previous days schedule, when looking for the previous time of day event. To
set an event at midnight use period 1, (00:15 hrs). Implemented through Table 7
The defaults for the Saturday, Sunday, and Holiday schedules are:
NSB = (00:15 hours) [Default 1]
Lights Off 1 = (00:15 hours) [Default 1]
The defaults for the weekday schedules are:
NSB #1 = (19:00 hours, 7 PM) [Default 76 decimal]
Lights Off 1 = (19:00 hours, 7 PM) [Default 76 decimal]
Occupied #1 = (07:00 hours, 7 AM) [Default 28 decimal]
Lights On 1 = (07:00 hours, 7 AM) [Default 28 decimal]
All others default to zero. [Default 0]

Table 13, Non-volatile Trend Setup

The trend interval is in 15 minute periods. The trend data always starts at
midnight. The first trend entry is at 00:00 hours as identified by the Trend Day of Week.
Trending only takes place when the controller is synchronized and when Trend Day of
Week is non-zero.
Both trends use the same date stamp and trend pointer.
The trend pointer is the offset from the starting byte based on the time that has elapsed
since mid-night on the Trend Date Stamp Day of Week. The trend may extend across
multiple days up to 1 week.
Two RAM data trends of 96 values have been assigned. Trend data is read from upper
half of Non-volatile using MT= 07h Read Multiple bytes from upper NON-VOLATILE,
or reading Table 254 Upper NON-VOLATILE,. Trend table 1 starts at MT= 07h, byte 0,
through byte 95, or Table 254, Entry 1 through 96. Trend table 2 starts at MT= 07h, byte
96, through byte 191, or Table 254, Entry 97 through 192.
When the calculated trend position exceeds 96 values, or the day returns to the current
Date, then the trend rolls over and begins again with the current Trend Day of Week.

Table 17, Non-volatile Input Raw Fault Limits

These 8 bit values are used to determine if the input raw readings are out of range. Note:
0 to 5 Vdc inputs will show a low fault if the voltage is below 0.06 Vdc or a high fault if
the voltage is above 4.70 Vdc.
