Parameterization and operation
4.5 2-channel RTC103 N-Module parameterization on the sc1000 controller
In addition to the 1-channel version, there is also a 2-channel
version that can control two activated sludge tanks. The relevant
parameters therefore appear twice and are identified as channel
1 and channel 2.
MODBUS
ADDRESS Start address of an RTC within the MODBUS network.
DATA ORDER
Specifies the register order within a double word. Presetting:
NORMAL
DATALOG INTRVAL Indicates the interval in which the data is saved in the log file. [min]
PROGNOSYS
Activate or deactivate PROGNOSYS for RTC control. "Activate"
means if Measurement Indicator from relevant sensor decrease to
50% or lower RTC control do not use this measurement and switch
to adequate fall back strategy.
SET DEFAULTS Restores the factory settings.
MAINTENANCE
RTC DATA
RTC MEASUREMEN
Specifies the value measured by the RTC, e. g. the influent
measurement.
RTC ACTUAT VAR
Specifies the variable calculated by the RTC, e. g. whether the
aeration should be switched on or off.
DIAG/TEST
EEPROM Hardware test
RTC COMM TO Communication time-out
RTC CRC Communication check sum
MODBUS ADDRESS
Here, the address is displayed where the communication actually
takes place. Presetting: 41
LOCATION
Here, a location name can be assigned for better identification of the
RTC module, e.g. activation 2.
SOFT-VERSION
Shows the software version of the RTC communication card
(YAB117) in the sc1000.
RTC MODE
Shows the installed RTC module variant, e.g. 1-channel closed-loop
control.
RTC VERSION Shows the software version of the RTC module.
