Word Description Bits
20 0 LoopĆ7 Enable
• 0 = Loop 7 disabled.
• 1 = Loop 7 enabled.
1 LoopĆ7 Auto/Manual Mode Select Ċ (controlled by bit 1 of word 26 of the dynamic block)
• 0 = Loop 7 is in the manual mode Ċ the manual output value (from word 29, dynamic block) is used as the CV value.
• 1 = Loop 7 is in the automatic mode Ċ the PID algorithm generates the CV value.
2 LoopĆ7 Open Circuit
• 0 = LoopĆ7 thermocouple circuit is closed (connection OK).
• 1 = .LoopĆ7 thermocouple circuit is open (connection broken).
3 LoopĆ7 Parameters valid
• 0 = Power has been interrupted since valid parameters for loop 7 have been blockĆtransferred.
• 1 = Valid parameters for loop 7 have been blockĆtransferred since last loss of power .
4 LoopĆ7 Calibration Fault
• 0 = LoopĆ7 calibration is OK.
• 1 = LoopĆ7 cannot operate with as calibrated.
5 LoopĆ7 SetĆPoint Select Ċ (controlled by bit 2 of word 26 of the dynamic block)
• 0 = Select the standbyĆtemperature setĆpoint value from word 27 of the dynamic block.
• 1 = Select the runĆtemperature setĆpoint value from word 28 of the dynamic block.
6 LoopĆ7 Parameter Value Error
• 0 = LoopĆ7 parameter values OK.
• 1 = LoopĆ7 parameter value error.
7 LoopĆ7 AutoĆTuning Complete
• 0 = LoopĆ7 autoĆtuning is not complete.
• 1 = LoopĆ7 autoĆtuning is complete.
8 Reserved.
9 Reserved.
10 LoopĆ7 Thermal Runaway Ċ (set in words 22 and 23 of the configuration block)
• 0 = LoopĆ7 is operating within thermal runaway limit..
• 1 = LoopĆ7 has exceeded the thermal runaway limit. and the CV value has been forced..
11 LoopĆ7 High CV Limit Ċ (set in word 7 of the configuration block)
• 0 = LoopĆ7 CV value is below the high CV limit.
• 1 = LoopĆ7 CV value is at the high CV limit.
12 LoopĆ7 Low CV Limit Ċ (set in word 8 of the configuration block)
• 0 = LoopĆ7 CV value is above the low CV limit.
• 1 = LoopĆ7 CV value is at the low CV limit.
