Interfaces
Further devices (e.g. volume converters, measured value remote transfer units) can be
connected to the FLOWSIC600-XT via the available interfaces. The interfaces accessible in
the terminal compartment are non-reactive. Available input/output configurations, see
.
2.6.1
Analog outputs
The FLOWSIC600-XT has an optional 4-20 mA analog output to output the various
measured values. The resolution of the output is 16 bit with an update rate of 8 Hz. The
accuracy of the analog output is ≤ 0.1 … 0.2%.
The behavior of the analog output for bidirectional operation can be selected in register
# 4021. By default, the negative flow rate (reverse direction) is output as a negative value
(linear behavior). When switching to bidirectional operation, an absolute value is always
output, independent of the flow direction.
It is recommended to check and, if necessary, adjust the analog output during commission

2.6.2
Digital outputs
The FLOWSIC600-XT has 4 digital outputs (FO.0, FO.1, DO.2 and DO.3) to output the
impulses proportional to the flow rate and status information. The digital outputs are
electrically isolated with a synchronous refresh in a configurable period between 0.1 to 1 s.
The refresh rate can be configured.
Status output
All the digital outputs can be configured individually to output various status information.
The following output modes are available:
● Inactive
The output remains at its set idle level. This setting is especially useful for low power
applications when the output is not used.
● Measurement valid
The output is only activated when the measurement is valid. The output is deactivated
when a device error occurs (system error or air test mode), or when maintenance mode
is active when the parameter locking switch is open.
● Error
The output is activated when a device error is present (system error or air test mode).
● Maintenance request
Maintenance request is reported and the output activated when measuring precision
can be impaired when a component fails or is configured incorrectly.
● User warning
The output is activated when a user limit is exceeded.
● Configuration mode
The output is activated when the device is in configuration mode.
● Reverse flow
The output is activated when the flow direction through the device is negative (reverse
flow).
