Digital / Relay Outputs
Variable
name: SNVT
type:
State:
nviDigitOutput SNVT_state_64 Boolean 1 bit x 64
This variable controls the state of the digital outputs and relays.
A logical 1 indicates that the output is on or active.
A logical 0 indicates that the output is off or inactive.
Bit 0 CC Digital Output Terminal 27
Bit 1 CC Digital Output Terminal 29
Bit 2 GPIO Digital Output Terminal X30/6
Bit 3 GPIO Digital Output Terminal X30/7
Bit 4 CC Relay 1 output terminal
Bit 5 CC Relay 2 output terminal
Bit 6 Option B Relay 1 output terminal
Bit 7 Option B Relay 2 output terminal
Bit 8 Option B Relay 3 output terminal
Bit 9-63 Reserved for future terminals
Analog Output (42)
Variable
name: SNVT
type:
Value:
nviAnOut1 SNVT_lev_percent
Min.: Max.: Resolution:
0 % 100 % 0.01%
This variable controls the analog output 42, 0–20 mA or 4–20 mA.
In order to control output 42 via LonWorks, par.6-50
Terminal 42 Output must be set to one of the following
options:
[139] Bus ctrl. 0–20 mA
[140] Bus crtl. 4–20 mA
[141] Bus crtl. 0–20 mA Timeout
[142] Bus crtl. 4–20 mA Timeout
Function:
Bus crtl. 0–20 mA [139]: The output is controlled via bus. In the event of bus timeout, the output level remains
unchanged.
Bus crtl. 4–20 mA [140]: The output is controlled via bus. In the event of bus timeout, the output level remains
unchanged.
Bus crtl. 0–20 mA [141]: The output is controlled via bus. In the event of bus timeout, the output level is set to
the predefined level in par.6-54
Terminal 42 Output Timeout Preset .
Bus crtl. 4–20 mA [142]: The output is controlled via bus. In the event of bus timeout, the output level is set to
the predefined level in par.6-54
Terminal 42 Output Timeout Preset .
