4.
Set static values which are not affected by the table UI function: current (register
501 or CURR command) and power (register 502 or POW command) IU function:
voltage (register 500 or VOLT command) and power (register 502 or POW
command) Step 5:
5.
Run the function generator with start/stop (register 850) resp., if still not done,
switch on the DC input/output of your unit (register 405). For PV mode and
function, you may also want to control irradiation while the function is running. This
is done by sending set values to register 501 (current), where 100% corresponds to a
factor of 1 and 0% to a factor of 0. This factor is multiplied to the simulated current
value IMPP, which you have to enter in the HMI as a parameter of the simulated
solar panel or which is defined by the loaded table.
6.
Exit the function generator by deselecting your former selection of either UI
(register 854), IU (register 855) or PV (register 426) again.
7.11.8
Registers 9000 - 9009 (Adjustment limits)
For SCPI use, see 7.12.9.1, “Adjustment Limit Commands” on page 152. ModBus users
should also read that section for the general handling of these settings. Apart from that,
setting these parameters is like setting a set value (U, I, P, R).
7.11.9
Registers 10007 - 10900
Those registers can be used to remotely configure the various built- in or optionally
available digital interfaces for the above stated series. The registers are connected to the
corresponding settings in the unit's setup menu, where featured. Contrary to manual
control, the settings for the interface modules can be configured while the interface module
is not yet installed.
7.11.10
Register from 12000 (PV simulation / DIN EN 50530)
Photovoltaics simulation is a function based on the XY generator.
The advanced simulation according to DIN EN 50530 is supported from firmware KE 2.19
and HMI 2.10. All ModBus registers which represent parameters related to this simulation
and can be written to the unit or read from are referenced in the EN 50530 standard
document. The document is furthermore the reference for the user regarding setup and
correct use of this simulation feature.
The procedure to set up and control the extended PV simulation using ModBus protocol is
no different to manual handling on the unit’s front panel or when using SCPI commands (see
examples in SCPI section Error! Reference source not found., “Error! Reference source not
found.” on page Error! Bookmark not defined.). These step by step examples have an extra
column in the table that holds the related ModBus register number. One of these examples
(nr. 2) converted to ModBus RTU format (percent set values translated for a unit with 80 V
and 170 A rating):
