Word Description
Bits
6
0
LoopĆ2 Enable
•
0 = Loop 2 disabled.
•
1 = Loop 2 enabled if PID control mode selected (bits 7-8, word 2, config block).
1
LoopĆ2 Auto/Manual Mode Select
•
0 = Loop 2 is in the manual mode Ċ the manual output value (from word 9) is used as the CV value.
•
1 = Loop 2 is in the automatic mode Ċ the PID algorithm generates the CV value.
2
LoopĆ2 SetĆPoint Select
•
0 = Select the standbyĆtemperature setĆpoint value from word 7.
•
1 = Select the runĆtemperature setĆpoint value from word 8.
3
LoopĆ2 AutoĆTuning Enable
•
0 = Disable autoĆtuning.
•
1 = Enable autoĆtuning Ċ autoĆtuning can be invoked by an offĆtoĆon transition of bit 1 of word 34.
4
Always = 0.
5
LoopĆ2 PID Integral Term Reset Enable
•
0 = Accumulate PID integral term.
•
1 = Reset the PID integral term on the 0ĆtoĆ1 transition, and then allow accumulation until the next 0ĆtoĆ1 transition.
6-15
Always = 0.
7
0-15
LoopĆ2 Standby Temperature SetĆpoint Value Ċ Used when bit 2 of word 6 is off (0 thru 999.9
).
8
0-15
LoopĆ2 Run Temperature SetĆpoint Value Ċ Used when bit 2 of word 6 is on (0 thru 999.9
).
9
0-15
LoopĆ2 Manual Output Value (CV) Ċ Used when bit 1 of word 6 is off (-100.00 thru +100.00).
10
0
LoopĆ3 Enable
•
0 = Loop 3 disabled.
•
1 = Loop 2 enabled if PID control mode selected (bits 7-8, word 2, config block).
1
LoopĆ3 Auto/Manual Mode Select
•
0 = Loop 3 is in the manual mode Ċ the manual output value (from word 13) is used as the CV value.
•
1 = Loop 3 is in the automatic mode Ċ the PID algorithm generates the CV value.
2
LoopĆ3 SetĆPoint Select
•
0 = Select the standbyĆtemperature setĆpoint value from word 11.
•
1 = Select the runĆtemperature setĆpoint value from word 12.
3
LoopĆ3 AutoĆTuning Enable
•
0 = Disable autoĆtuning.
•
1 = Enable autoĆtuning Ċ autoĆtuning can be invoked by an offĆtoĆon transition of bit 1 of word 34.
