Description This data object is intended for remote control of the gen-set via the
communication if some kind of data is to be passed into the controller.
This object can be written via the communication (e.g. Modbus) without any
limitation. Use GenConfig function Generate Cfg Image to get the
communication object number or register number of this particular value
object. Below is a typical example of using this object.
E
XAMPLE
:
The gen-set group is required to be running in parallel-to-mains mode at
constant load level (baseload), however the system baseload level is
adjusted from a supervisory PLC system via Modbus.
C
AUTION
!
It is not allowed to solve this task by cyclic writing of the baseload setpoint
from the supervisory device. The EEPROM memory may become damaged
when any setpoint is written repeatedly with a short period.
The proper solution is following:
1. Go to GenConfig, download the configuration from the controller,
select the LAI tab and configure the logical analog input
MLC:AnExSysBld onto the ExtValue1 , which is located in the Force
value group. If you do not see the LAI tab you have to switch the
GenConfig to "advanced" mode. Then upload the configuration into
the controller.
2. Go to InteliMonitor and change the setpoint MLoad ctrl PtM to
ANEXSYSBLD->LS.
3. Now you have to program your PLC to write requested gen-set
baseload into the Modbus register ExtValue1 (register number 40392
for IG/IS-NT-2.4).
