Name: SET_MFC
Type: Cyclic Write (small & full)
Size: 6
Description: Analog Output Transducer Block, Small & Full Setup
Parameters:
Name Add. Type Comment
VALVE_OVERRIDE 1:0 uint:2 NORMAL, FLOW_OFF, PURGE
AUTOZERO 1:2 uint:1 0 to 1 transition activates zeroing if
(VALVE_OVERRIDE==FLOW_OFF &&
FLOW_SETPOINT < 5%FS)
REPORT_DIAG 1:3 uint:3 transition to a new value, triggers the device to
send a new actual diagnosis:
0 = no diagnosis
1 = diagnosis of small functionality
2 = diagnosis of full functionality
3 = report selected gas table
4..7 = reserved
WINK_STATUS 1:6 uint:1 0 to 1 transition sets the LED to blink red/green
for 3 seconds
ENABLE_TOTALIZER 1:7 uint:1 0 = disabled, 1 = enabled
RESET_TOTALIZER 0:0 uint:1 0 to 1 transition resets totalizer to zero
RESET_STATUS 0:1 uint:1 0 to 1 transition resets error status bits
SELECT_GAS_TABLE 0:2 uint:4 0..14; 15 = default gas table is used
EN_GAS_CORRECTION 0:6 uint:1 0 = disabled, 1 = enabled
Reserved 0:7 uint:1
FLOW_SETPOINT 2:0 long in [FLOW_UNIT] in 10E-4 steps
valve switched off if setpoint < 1%
valve switched on if setpoint > 2%
If the device is in the analog mode (i.e. set point is taken from the analog interface) some functions
are not active:
1. VALVE_OVERRIDE is not active
2. EN_GAS_CORRECTION is not active
3. SELECT_GAS_TABLE is not active and the default table will be used
