The dynamic block contains 34 words as follows:
Words 1 thru 34 of the dynamic block are identified by the mnemonics
TDC01 thru TDC34 in ProSet 700 software.
Word Bits Description
1 0-15 Block Identification Code Ċ 1000 1000 0000 1010 (880A
16
)
2 0 LoopĆ1 Enable
• 0 = Loop 1 disabled.
• 1 = Loop 1 enabled if PID control mode selected (bits 7-8, word 2, config block).
1 LoopĆ1 Auto/Manual Mode Select
• 0 = Loop 1 is in the manual mode Ċ the manual output value (from word 5) is used as the CV value.
• 1 = Loop 1 is in the automatic mode Ċ the PID algorithm generates the CV value.
2 LoopĆ1 SetĆPoint Select
• 0 = Select the standbyĆtemperature setĆpoint value from word 3.
• 1 = Select the runĆtemperature setĆpoint value from word 4.
3 LoopĆ1 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 LoopĆ1 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 Not used.
3 0-15 LoopĆ1 Standby Temperature SetĆpoint Value Ċ Used when bit 2 of word 2 is off (0 thru 999.9 ).
4 0-15 LoopĆ1 Run Temperature SetĆpoint Value Ċ Used when bit 2 of word 2 is on (0 thru 999.9 ).
5 0-15 LoopĆ1 Manual Output Value (CV) Ċ Used when bit 1 of word 2 is off (-100.00 thru +100.00).
