Data Modules Of The Ssm6000 - PRONOVA SSM 6000 User Manual

Description
PROFIBUS interface
The same error message is generated if the "Measurement" data module was selected (parameterized) for cyclic data exchange.
Otherwise the output value which is output in acyclic mode would be cyclically overwritten.
Write access is possible via index 2 only. Write access attempts with another index trigger the "DPV1_ERRCL_ACC_INV_INDEX"

Data modules of the SSM6000

The SSM6000 provides the following data modules:
Description
CH4 (measuring gas)
H2S (measuring gas)
O2 (measuring gas)
CO2 (measuring gas)
Pressure
Temperature (inside)
Alarm
Status
Measurement
Analog Input 1..11
CH4 measuring gas:
The measuring range is from 0.0 to 99.9 % by volume. The measured value is updated after each measuring process and is then
maintained until polled.
H2S measuring gas:
The measuring range is from 0 to 5000 ppm. The measured value is updated after each measuring process and is then maintained
until polled.
O2 measuring gas:
The measuring range is from 0.0 to 25.0 % by volume. The measured value is updated after each measuring process and is then
maintained until polled.
CO2 measuring gas:
The measuring range is from 0.0 to 99.9 % by volume. The measured value is updated after each measuring process and is then
maintained until polled.
Pressure measured value:
The pressure value is updated every second and made available for polling.
Temperature (inside) measured value:
The temperature inside the unit is measured after each discontinuous measuring process or, during continuous measurement, every
2 seconds. Furthermore, the temperature is measured each time the key-operated switch is changed between measuring mode and
setup mode.
