16. INTEGRAL GAIN
Write Command: 1e
Read Command: 52
Interpret:
Fixed‐point gain in repeats/min.
Multiply desired integral 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.
17. 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.
