Warning
Electric shock hazard! Danger to life and limb!
There is a risk of electric shock when connecting the device to the
power supply. This can result in life-threatening injuries.
–
De-energize the power cable and take measures to prevent it from
being re-energized.
Note
Damage due to improperly connected cables!
If cables are improperly connected, this can damage or destroy the
measuring inputs and the device.
–
Connect cables only to the correct locations.
–
Ensure the correct polarity of the cables being connected.
Note
Damage due to overvoltage!
Overvoltage or voltage peaks can damage or destroy the device.
–
Protect the power supply against overvoltage.
Note
Damage due to overvoltage!
If voltages of more than 10 V DC are applied to the analogue inputs,
or if currents of more than 20 mA flow, this can destroy the affected
measuring inputs.
–
Ensure that only voltages of up to 10 V DC are applied and only
currents of up to 20 mA flow.
Note
Damage due to overvoltage!
If voltages of more than 24 V DC are applied to the digital inputs, this
can destroy the affected measuring inputs.

(e.g. provider number; if necessary, include external dial prefix and
ensure there are no dialing restrictions). Set the telephone system as
described in the manufacturer’s instructions.
2. Test the ISDN telephone connection with an S0 tester before installation.
Set the telephone system as described in the manufacturer’s
instructions.
3. For PSTN or ISDN, connect the device and the telephone connection
with the supplied cable. If the cable needs to be extended, ensure secure
contact and correct polarity.
4. For a GSM/GPRS modem, connect the supplied mobile radio antenna to
the antenna socket.
5. The GSM/GPRS data card must be set to the same PIN number as the
WEB'log. To do this, set the PIN number of the data card using a cell
phone. Insert the GSM/GPRS data card into the WEB'log until you feel it
click into place.

WEB'log
4.5
Communication with inverters
In order for the WEB'log to communicate with the inverter, the data logger
must be equipped with the appropriate inverter driver.
Note: The required driver is installed by the manufacturer before shipment.
This section lists only the information necessary for connecting inverters and
current sensors. Additional information is available in the Inverter / current
sensor documents.
Please note:

Observe the maximum permissible number of bus devices

WEB'log and connect the first bus device with the data cable or
connect cable.

The order of the bus devices on the bus is unimportant

The use of a repeater is necessary for every 32nd bus device and
for long cable lengths

As a rule, no operating voltage may be connected to the
communication interfaces of inverters

The i'checker requires a power supply of 24 V DC

The shield of the bus cable must be grounded at one end of the
connection only. The data logger does not have its own grounding

When routing the bus cabling, ensure as great a distance as
possible from AC cables

To prevent reflections, the bus must always be terminated with a
parallel terminator
“Connect cable” option
meteocontrol offers a pre-assembled data cable (Connect cable) for
connecting the WEB'log and the first bus device (inverter or current sensor).
Please select the connect cable according to the inverter type or use the
meteocontrol Connect Universal RS cable.
WEB'log
19/92
4.5.1
WEB'log RS485 connection
This interface serves as the default connection between the WEB'log and
inverter. Connection information for the relevant inverter type can be found
in Appendix Chapter 8.1. If the inverter type is not listed in the Appendix, the
general connection diagram illustrated below must be used. Please also
observe the additional information included with the inverter manufacturer
documentation!

(5) Possible connection names

Signal wires RS485 A and RS485 B must not be interchanged

A twisted and shielded wire pair must be used for the bus cable

Terminate RS485 bus after the last bus device
(using resistor, switch, jumper ... depending on type)
Note: This interface is not to be used to connect auxiliary Modbus devices!
Please use the interface RS232/RS422 as described in 4.5.2 .
20/92
WEB'log
4.5.2
Connecting Modbus devices
Not all inverters operated via the RS485 interface of the WEB'log use the
Modbus communication protocol. Simultaneous operation of a Modbus
device at the RS485 interface is thereby not possible.
In these instances, the WEB'log allows Modbus devices to be operated via
the second serial interface RS232/RS422. The interface needs to be
configured accordingly with RS422 operation:
1.
Turn off WEB'log power supply.
2.
For switching to the RS422 move the right switch on the WEB'log
(behind DO1 connection) to Position 1 (looking at the connection from
the front: to the left).
3.
Convert the serial cable according to the Pin assignment (see Fig.
13) or use meteocontrol Connect Universal RS (already includes
modifications).
4.
Connect the serial cable to the RS485 terminals of the auxiliary
device and to the RS232/RS422 socket of the WEB'log.
 Auxiliary device is connected to the WEB'log via RS485.

Configuring the WEB'log for Power Control
The necessity of active participation of PV system operators in the grid
safety management increases with the rising share in the overall power
production. This requires an option to reduce the feed-in power and
participation in the compensation of the reactive power in the grid. Power
control procedures provide a number of options for implementing these
requirements.
In the following, power control procedures are outlined that can only be
performed with WEB'log and ripple control receivers. An overview of all
possible procedures is available in Chapter 8.2.
A detailed description of the procedures and how the configuration is to be
performed can be found on our Internet page www.meteocontrol.com.
5.7.1
Active power control (P(DI) internal)
With all data loggers, it is possible to carry out a reduction in active power for
PV systems. The manipulated variables specified by the relevant energy
supplier are transmitted to the WEB'logs using the ripple control receiver.
Connecting the ripple control receiver to the digital interfaces

(4) Digital input DI3 (Default 30%)
(5) Digital input DI4 (Default 0%)
WEB'log
Configuring the active power control via the Web browser

Login to the admin area of the expert pages via the menu General >
Login.

In the menu, select Admin measurement > Power Control > General
configuration

Select active power procedure “P(DI) intern“ and configure the digital
inputs according to their active power level

"Data logger mode" can be used to specify whether the device should
send the information received from the ripple control receiver to
additional WEB'logs in the network

In the section "Control values in fallback mode", the valid active power
control value for a communication disruption to the ripple control receiver
can be set.

Power control is activated by checking the box "Power Control Active"
and confirming with "Save"
Note: The Power Control can be set to active or inactive on the display.
Other Power Control configurations can only be made via the Web
pages of the WEB'log.
5.7.2
Reactive Power Control cos φ (Fix) and Q (Fix)
All WEB'logs also enable the setting of fixed reactive power values for PV
systems. A power quality analyser and related accessories are required to
carry out reactive power control at a grid connection point.
The following configuration steps must be performed to set fixed reactive
power values
 Login to the admin area of the expert pages via the menu General >
Login
 In the menu, select Admin measurement > Power Control > General
configuration
 Select reactive power procedures “cos φ (Fix)“ and “Q (Fix)“ and enter
the fixed reactive power value specified by the energy supplier
 "Data logger mode" can be used to specify whether the device should
send the information received from the ripple control receiver to
additional WEB'logs in the network
 Power control is activated by checking the box "Power Control Active"
and confirming with "Save"
WEB'log
29/92
5.7.3
WEB‘log Master and Slave
In large systems with multiple data loggers, Power Control can be managed
by a WEB'log master. The control values are determined by the master and
transmitted to the WEB'log slaves. They then forward the control values to
the inverters.


All WEB'log devices must be in the same network (subnet mask).

Every WEB'log must be assigned its own IP address.

A maximum of two WEB'log devices may be directly connected via a
cross cable.

For more than two WEB'log devices, an Ethernet switch is required.
WEB'log
Defining the WEB'log as Master or Slave
Master and slave configurations are set on the WEB'log Web pages. To do
this, the computer must be connection with the WEB'log via Ethernet.
The following steps are required for the configuration via Web browser:

Login to the admin area of the expert pages via the menu General >
Login.

In the menu, select Admin measurement > Power Control > General
configuration

Select data logger mode
Note: The data logger activated as the master sends information on active
and reactive power values to slaves. Active and reactive power
procedures can be set and configured on the master only.
Note: If the Master is a WEB’log Pro Unlimited, also WEB’log Light + 20
and Basic 100 can be used as slaves for all power control
procedures.
The following list illustrates the options for Master and Slave settings:
WEB'log

Slave (general broadcast messages)
Receives control value information from the master about the general
broadcast

Slave (Einzelmeldungen) [Slave (single messages)]
Receives control value information from the master via single message

Slave (Gruppen-Broadcast) [Slave (group broadcast)]
Receives control value information from the master via group broadcast

Master (keine) [Master (none)]
Transfers no control value information to slaves

Master (an alle Slaves) [Master (to all slaves)]
Transfers control value information as a broadcast to all slaves available

Master (Slavegruppe) [Master (slave group)]
Transfers control value information as a broadcast to all slave groups
