Word Description Bits
17 0 LoopĆ6 Enable
• 0 = Loop 6 disabled.
• 1 = Loop 6 enabled.
1 LoopĆ6 Auto/Manual Mode Select Ċ (controlled by bit 1 of word 22 of the dynamic block)
• 0 = Loop 6 is in the manual mode Ċ the manual output value (from word 25, dynamic block) is used as the CV value.
• 1 = Loop 6 is in the automatic mode Ċ the PID algorithm generates the CV value.
2 LoopĆ6 Open Circuit
• 0 = LoopĆ6 thermocouple circuit is closed (connection OK).
• 1 = .LoopĆ6 thermocouple circuit is open (connection broken).
3 LoopĆ6 Parameters valid
• 0 = Power has been interrupted since valid parameters for loop 6 have been blockĆtransferred.
• 1 = Valid parameters for loop 6 have been blockĆtransferred since last loss of power .
4 LoopĆ6 Calibration Fault
• 0 = LoopĆ1 calibration is OK.
• 1 = LoopĆ1 cannot operate with as calibrated.
5 LoopĆ6 SetĆPoint Select Ċ (controlled by bit 2 of word 22 of the dynamic block)
• 0 = Select the standbyĆtemperature setĆpoint value from word 23 of the dynamic block.
• 1 = Select the runĆtemperature setĆpoint value from word 24 of the dynamic block.
6 LoopĆ6 Parameter Value Error
• 0 = LoopĆ6 parameter values OK.
• 1 = LoopĆ6 parameter value error.
7 LoopĆ6 AutoĆTuning Complete
• 0 = LoopĆ6 autoĆtuning is not complete.
• 1 = LoopĆ6 autoĆtuning is complete.
8 Reserved.
9 Reserved.
10 LoopĆ6 Thermal Runaway Ċ (set in words 22 and 23 of the configuration block)
• 0 = LoopĆ6 is operating within thermal runaway limit..
• 1 = LoopĆ6 has exceeded the thermal runaway limit. and the CV value has been forced..
11 LoopĆ6 High CV Limit Ċ (set in word 7 of the configuration block)
• 0 = LoopĆ6 CV value is below the high CV limit.
• 1 = LoopĆ6 CV value is at the high CV limit.
12 LoopĆ6 Low CV Limit Ċ (set in word 8 of the configuration block)
• 0 = LoopĆ6 CV value is above the low CV limit.
• 1 = LoopĆ6 CV value is at the low CV limit.
