APPENDIX 3. SETTING OF AV550G-
SPECIFIC COMMANDS
Byaccessing the parameters of the transducer block, it is possible to execute commands
specificto the AV550G.
A3.1 AV550G-specific Commands
A3.2 Setting of AV550G-specific Commands
(1) Start Calibration Command
Access the CHx_SEMIAUTO_CAL_START (x = 1 to 8) parameter.
Setting the parameter to 2 (START) allows manual calibration to be performed.
For example, set CH1_SEMIAUTO_CAL_START (189) to 2, to perform manual calibration on the
channel-1 card. (189 is a relative index.)
This function does not operate unless the calibration mode of the AV550G is set to Semi-Auto or Auto.
For details, refer to the AV550G’s user’s manual.
(2) Start Indication Checking Command
Access the CHx_INDICATION_START (x = 1 to 8) parameter.
Setting the parameter to 2 (START) allows indication checking to be performed.
For example, set CH1_INDICATION_START (197) to 2, to perform indication checking on the
channel-1 card. (197 is a relative index.)
This function does not operate unless the indication check mode of the AV550G is set to Semi-Auto or
Auto.
For details, refer to the AV550G’s user’s manual.
Command Summary
Start Calibration
(CHx_SEMIAUTO_CAL_START, where x is the channel number)
Instructs the AV550G to perform manual calibration on its individual
channel cards.
Start Indication Checking
(CHx_INDICATION_START, where x is the channel number)
Instructs the AV550G to perform indication checking on its individual
channel cards.
Start Blow Back (BLOWBACK_START) Instructs the AV550G to perform a blow back.
Calibration Gas Pressure Drop (CAL_GAS_PRESS_DROP_SW) Informs the AV550G of a drop in the calibration gas pressure.
Process Gas Alarm (PROCESS_GAS_ALARM_SW) Informs the AV550G that a process gas alarm has been generated.
