SECTION 9. INPUT/OUTPUT INSTRUCTIONS
data line became active. If this occurs the
sensor CR10 will not respond to the SDI-12
recorder. Most instructions execute fast enough
that when Instruction 106 misses the initial SDI-
12 address, a subsequent retry by the recorder
will work.
PARAM. DATA
NUMBER TYPE
01: 4
02: 4
03: 4
Input locations altered: 0
Intermediate locations required: 82. This
requires that the default setting of 64 be
increased. The *A mode (second window) is
used to specify Intermediate locations.
PARAMETER 1. ADDRESS
Enter the address for the CR10 acting as a
SDI-12 sensor (0-9). Each SDI-12 sensor must
have a unique address. Non standard
addresses may be used by entering the
appropriate ASCII code.
PARAMETER 2. TIME/VALUES
Enter the time required for the sensor CR10 to
complete subroutine 98 followed by the number
of input locations to be returned to the SDI-12
recorder. The format of the entry must be 'tttn'
where ttt specifies the time and n is the number
of input locations values.
The time to complete subroutine 98 is the time
required to execute all instructions from
Instruction 106 (SDI-12 sensor) to the final
Instruction 95 (End). The entered time may be
longer than the actual time without slowing the
data exchange because the sensor CR10
signals the SDI-12 data recorder when the data
is ready for transfer. If the entered time is too
short the sensor CR10 will not respond properly
and the data values will not be transferred.
Enter a time of 0 to transfer the values already
stored in input locations, in this case the
remainder of the subroutine is not executed.
A maximum of 9 input locations can be
transferred at one time since 'n' is a single digit.
