Function description
OUTPUTS → PULSE/FREQUENCY OUTPUT 1 → OPERATION (PULSE)
SIMULATION
PULSE
MODBUS register:
Data type:
Access:
4322
3233
Integer
read/write
! Note!
Function is not available unless the PULSE setting was selected in the
OPERATION MODE function (4200).
Use this function to activate simulation of the pulse output.
Options:
0 = OFF
1 = COUNTDOWN
The pulses specified in the VALUE SIMULATION PULSE function are output.
2 = CONTINUOUSLY
Pulses are continuously output with the pulse width specified in the PULSE
WIDTH function. Simulation is started once the CONTINUOUSLY option is
confirmed with the F key.
! Note!
Simulation is started by confirming the CONTINUOUSLY option with the F key.
The simulation can be switched off again via the SIMULATION PULSE function.
Factory setting: OFF
! Note!
• The notice message #631 “SIM. PULSE” indicates that simulation is active.
• The on/off ratio is 1:1 for both types of simulation.
• The measuring device continues to measure while simulation is in progress, i.e.
the current measured values are output correctly via the other outputs.
" Caution!
The setting is not saved in the event of a power failure.
VALUE
SIMULATION
PULSE
MODBUS register:
Data type:
Access:
4323
3234
Float
read/write
! Note!
Function is not available unless the COUNTDOWN setting was selected in the
SIMULATION PULSE function.
Use this function to specify the number of pulses (e.g. 50) which are output
during the simulation. This value is used to test downstream devices and the
measuring device itself. The pulses are output with the pulse width specified in
the PULSE WIDTH function. The on/off ratio is 1:1.
Simulation is started once the specified value is confirmed with the F key.
The display remains at 0 if the specified pulses have been output.
User input: 0 to 10 000
Factory setting: 0
! Note!
Simulation is started by confirming the simulation value with the F key. The
simulation can be switched off again via the SIMULATION PULSE function.
" Caution!
The setting is not saved in the event of a power failure.
