RKI Instruments GD-70D Series User Manual

- 55 - GD-70D
You can select the transmission status with the combination of the setting point of nciMaxSendTM (8) and
nciMinSendTM (9).
・nciMaxSendTM (8) ＝ Asec nciMinSendTM (9) = Bsec －－＞ (1) and (2) transmit every Asec when
there is no VAL update. If Bsec has not elapsed since last transmission, wait until Bsec has elapsed
before sending it even if VAL is updated.
・nciMaxSendTM (8) ＝ Asec nciMinSendTM (9) = 0sec －－＞ (1) and (2) transmit every Asec when
there is no VAL update. If there is an update of VAL, it will be sent immediately.
・nciMaxSendTM (8) ＝ 0sec nciMinSendTM (9) = Bsec －－＞ (1), (2) don’t transmit every Asec
when there is no VAL update. If Bsec has not elapsed since last transmission, wait until Bsec has elapsed
before sending it even if VAL is updated.
You can select the transmission status with the combination of the setting point of nciMaxSendTI (10) and
nciMinSendTI (11).
・nciMaxSendTI (10) ＝ Asec nciMinSendTI (11) = Bsec －－＞ (3) ~ (5) transmit every Asec when
there is no VAL update. If Bsec has not elapsed since last transmission, wait until Bsec has elapsed
before sending it even if VAL is updated.
・nciMaxSendTI (10) ＝ Asec nciMinSendTI (11) = 0sec －－＞ (3) ~ (5) transmit every Asec when
there is no VAL update. If there is an update of VAL, it will be sent immediately.
・nciMaxSendTI (10) ＝ 0sec nciMinSendTI (11) = Bsec －－＞ (3) ~ (5) don’t transmit every Asec
when there is no VAL update. If Bsec has not elapsed since last transmission, wait until Bsec has elapsed
before sending it even if VAL is updated.
NO. Variable name Variable type Contents
1 nvoConc SNVT_ppm_f
It is the same as the current density output.
Floating point of 16 BIT synchronizes with the display of the detection
part.
2 nvoNstate SNVT_state
It is the same as the current density output.
Status of 16 BIT expresses measurement unit, alarm, breakdown etc.
3 nvoAlarmS SNVT_switch
Expression of alarm state by switch
OFF:{0.0,0}
1st
:{1.0,1}
2nd :{1.5,1}
1st & 2nd: {2.0,1}
4 nvoFaultS SNVT_switch
Expression of fault condition by switch
Normal：{0.0,0}
Fault:{X.X,1} - - X.X : 1.0 = Sensor fault
: 5.0 = Flaw rate fault
: 7.0 = Pyrolyzer fault
: 9.0 = System fault
5 nvoGasName SNVT_str_asc
Send measured gas name and measurement unit in ASCII character
string.
From the beginning, we send unit after space (20H) with gas name
and the rest is ASCIL(00H = NULL)
6 nvoHertBeat SNVT_state
Count up 8 BIT of 0 to 7 of 16 BIT
Count every second and count it. If it is OVER, start with 0.
8 to 15 BIT is reserved.
7
nviReset
SNVT_lev_disc
RESET signal in case of self-latching 0:non not 0:RESET
8
nciMaxSendTM
SNVT_time_sec
1 and 2 update maximum time
9
nciMinSendTM
SNVT_time_sec
1 and 2 update minimum time
10
nciMaxSendTI
SNVT_time_sec
3 ~ 5 update maximum time
11
nciMinSendTI
SNVT_time_sec
3 ~ 5 update minimum time
5
nciMaxSendHB
SNVT_time_sec
6 update maximum time
13
nviComand
SNVT_str_asc
Command input of ASCII 30 byte
14
nvoComand
SNVT_str_asc
Command output of ASCII 30 byte
