42 ID_NODE - This is the unit's network node address. Note that if this
variable is changed then all future communication must be addressed to
the new node address.
52 ID_SERIAL_NUMBER - This is the serial number for the unit. It is
programmed at the factory and should not be changed by the user.
53 ID_VERSION_NUMBER - This is the version number of the
embedded software.
9.3 Inner Loop Tuning Variables
35 ID_INNER_PROPORTIONAL_CONSTANT - This is the P-term,
proportional constant, for the inner loop.
28 ID_INNER_INTEGRAL_CONSTANT - This is the I-term, integral
constant, for the inner loop.
3
ID_INNER_D_COEF1 - This is the D-term, derivative constant, for the
inner loop.
50 ID_INNER_INTEGRAL_MINIMUM - This is the minimum value
allowed for the integral sum on the inner loop.
29 ID_INNER_INTEGRAL_MAXIMUM - This is the maximum value
allowed for the integral sum on the inner loop.
30 ID_INNER_INTEGRAL_SUM - This is the value of the integral sum
for the inner loop. It is formed by multiplying the integral constant time
the error and summing the result with the previous value for the integral
sum.
66 ID_INNER_INTEGRAL_DEADBAND - This is the inner loop
minimum error required for the integral sum to be changing in value.
Often it is set to zero and has no effect. However, if it is desirable to
stop integrating once the error is reduced below a certain value, for
instance when using an external dome-loaded regulator which has
hysteresis, then this parameter should be set to the minimum acceptable
error.
6
ID_COMPENSATED_INTERNAL_SENSOR - This is the
compensated internal sensor value, i.e. - after temperature
compensation, zero and span have been applied to the raw signal. A
value of 400 is 0% and 3700 is 100%.
9.4 Outer Loop Tuning Variables
25 ID_OUTER_PROPORTIONAL_CONSTANT - This is the P-term,
proportional constant, for the outer loop.
21 ID_OUTER_INTEGRAL_CONSTANT - This is the I-term, integral
constant, for the outer loop.
16 ID_OUTER_D_COEF1 - This is the D-term, derivative constant, for
the outer loop.
49 ID_OUTER_INTEGRAL_MINIMUM - This is the minimum value
allowed for the integral sum on the outer loop.
