DERIVATIVE GAIN
Write Command: 1f
Read Command: 53
Interpret:
Fixed-point gain in minutes.
Multiply desired derivative gain by 100
10
and convert to hexadecimal for the
“send value.” When reading, convert the “return value” to decimal and divide
by 100
10
to interpret.
18.
LOW EXTERNAL SET RANGE
Write Command: 20
Read Command: 54
Interpret:
Value mapped to zero voltage of Input2. Only integer values are allowed.
Remember to convert to hexadecimal before sending.
19.
HIGH EXTERNAL SET RANGE
Write Command: 21
Read Command: 55
Interpret:
Value mapped to 5 volt or maximum voltage of Input2. Only integer values
are allowed. Remember to convert to hexadecimal before sending.
20.
ALARM DEADBAND
Write Command: 22
Read Command: 56
Interpret:
Temperature Input1 must move to toggle alarm output. When writing, first
multiply the desired deadband setting by 100
10
and convert to hexadecimal
for the “send value.” When reading, convert the “return value” to decimal
and divide by 100
10
to covert to °F/°C.
21.
HIGH ALARM SETTING
Write Command: 23
Read Command: 57
Interpret:
Temperature reference to compare against Input1 for high alarm output.
When writing, first multiply the desired setting by 100
10
and convert to
hexadecimal for the “send value.” When reading, convert the “return value”
to decimal and divide by 100
10
to covert to °F/°C.
22.
LOW ALARM SETTING
Write Command: 24
Read Command: 58
Interpret:
Temperature reference to compare against Input1 for low alarm output.
When writing, first multiply the desired setting by 100
10
and convert to
hexadecimal for the “send value.” When reading, convert the “return value”
to decimal and divide by 100
10
to covert to °F/°C.
23.
CONTROL DEADBAND SETTING
Write Command: 25
Read Command: 59
Interpret:
Temperature or count span Input1 must move to toggle control output.
When writing, first multiply the desired setting by 100
10
and convert to
hexadecimal for the “send value.” When reading, convert the “return value”
to decimal and divide by 100
10
to covert to °F/°C.
