4.3.2.3
I/O configuration
The input and output parameters are preset according to the ordered configuration.
[1]
DSFG Instance F is correctly implemented according to ISO17089-1:2019 Appendix F and supports the
register values listed here.
▸
Check the parameters and adapt when necessary, e.g. setting the correct Modbus
addresses.

I/O configuration
A fixed frequency can be stored in field “Error Frequency” which is output if there is a fault.
This value is stored in Register #4014 “Impuls_ErrorFrequency” of the meter. The function
is deactivated when value 0 is stored.
A time interval can be specified in the “Hold time” field in which the measured value is held
at the last valid value when the status changes from measurement valid to measurement
invalid. This value is stored in Register #4015 “Impulse_HoldTime” of the meter. The
function can be used, for example, to bridge short-term disturbances for control purposes.
● The configuration of the RS485.1 interface at the factory is performed for
trouble-free communication on test benches as follows:
-
Protocol type: MODBUS-RTU
-
Modbus configuration: FL600XT (standard)
-
Baud rate: 38,400 baud
-
Bit protocol: 8N1
● When an interface is configured with DSFG instance F, the parameters are
set according to the DSFG specification as follows:
-
Protocol type: MODBUS-RTU
-
Modbus configuration: DSFG
1
-
Baud rate: 9,600 baud
-
Bit protocol: 8E1
The interface marked on the right is always shown highlighted on the left of
the Figure. Clicking on the Figure selects the corresponding interface on
the right.
