Tariffs
MID-approved
See also
2.1 Features
SENTRON PAC2200 supports 2 tariffs for the integrated energy counter (on-peak and
off-peak).
Switching between tariffs
Tariff switching can be controlled via the digital input or the
communication interfaces.
Time-related switching is only possible using a higher-level system.
Tariff switching after synchronization
When synchronizing the power demand values via the communication interfaces
or the digital input, the tariff change will only become effective after expiry of the
period. Without synchronization, the tariff change takes effect immediately.
The synchronization frame contains the length of the demand period in minutes. The
synchronization command is ignored if the period length sent to the device with the
synchronization frame is different to the length parameterized in the device.
MID-approved devices are included in the portfolio. These devices are suitable for billing the
active energy.
The following actions cannot be carried out on MID-approved devices:
● FW update
● Resetting the secondary energy values
● Parameterization of the voltage input
● Inversion of the direction of current flow
The secondary value of the total active energy is suitable for billing purposes.

Averaging measured values
2.3 Averaging measured values
L2 apparent energy tariff 1 ✓ —
With appropriate load profiles, consumers can carry out a targeted optimization of their
energy consumption.
Instantaneous values are averaged over specific time periods to create load profiles. For this
purpose, measured values are read out via the communication and stored. This
increases the bus load considerably and occupies storage capacity.
The PAC2200 device has two average value generators, which can be parameterized
independently.
The aggregation of the measured values reduces the bus load without risk of loosing
information. Average values are calculated contiguously, based on the underlying values.
The values are updated each time after expiry of the set time period.
The default setting for average value 1 is a period length of 10 seconds.
The default setting for average value 2 is a period length of 15 minutes.
The period length can be set to anything between 3 seconds and 31536000 seconds (1
year).
This function is only available if communication interfaces via Modbus TCP/RTU are used.
The list of available measured values can be found in the appendix A.1.4 „Modbus variables
with function code 0x14“ on page 82 (Page 92).

Adjustable parameters
2.3 Averaging measured values
● The PAC2200 measuring device supplies the power demand of the last completed
measuring period:
● Mean values for active and reactive power, separately for import and export.
● Minimum and maximum active power and reactive power within the last measuring
period.
● Length of the measuring period in seconds. The period may be shorter for reasons of
external synchronization.
● Time in seconds since the last synchronization or since completion of the last period.
Period length: 15 minutes; time of day: 13:03; time in seconds: 180 s.

The digital output is passive and implemented exclusively as a switch.
Implementation of the pulse function corresponds to the IEC 62053-31 standard.
Figure 2-3 Pulse length and turn-off time
● Pulse length:
Time for which the signal at the digital output is "high". The minimum pulse length is
30 ms and the maximum 500 ms.
● Turn-off time:
Time for which the signal at the digital output is "low". The turn-off time depends on the
measured energy, for example, and can be days or months.
● Minimum turn-off time:
The minimum turn-off time corresponds to the programmed pulse length. 30 ms is the
absolute minimum.
Depending on the device version, the devices may be fitted with the following
communications interfaces:

2.5 Communication
Permits communication via the following protocols:
●
The device can be configured via Modbus TCP
●
Protocol can be used to read out the measured values via web browser.
●
The SNTP (Simple Network Time Protocol) is used to automatically synchronize the internal
clock with a time server within the network.
Three function modes are available:
● No synchronization.
● Date/time synchronization via device request
The IP address of an NTP server must be configured. With this, the PAC2200
automatically requests the current time from the server and resets its internal clock, if
necessary.
● Date/time synchronization via SNTP server - Broadcast
The PAC2200 receives Broadcast time telegrams, which are sent from an NTP server.
This is practical, if the internal clocks in several devices in the same network
should be synchronous.
If the IP address of the NTP server has been configured, the PAC2200 only responds to
these telegrams. Furthermore, it can send a request to the server, if necessary.
●
Stands for "Dynamic Host Configuration Protocol". Protocol for obtaining network settings
from a DHCP server. Network settings are automatically assigned.

RS 485
Note
RS 485 termination is recommended!
In order to avoid reflection on the bus cable, we recommend fitting a 120
resistor at the beginning and end of the bus cable.
2.5.3
M-BUS
2.5 Communication
Permits communication via the MODBUS RTU protocol. This interface features simple
topology and high immunity against EMC interference.
The data is transmitted differentially via two wires A and B. The third wire "COM" serves as
the common ground potential.
Grounding of the cable shield:
The serial Modbus data cable should be shielded. The shield should be connected to
protective ground at one end of the cable at least.
Grounding of the COM line:
Many masters do not have a common terminal. If this is the case, then RS 485 common
should reference the same functional ground as the master (at a single point). If the
master has a common terminal, then the common is connected to it, and it is not connected
to functional ground.
Ohm terminating
M-BUS is the abbreviation for Meter-Bus according to EN13757. The M-BUS is used as a
fieldbus for the acquisition of consumption data. The data is serially transmitted over a
reverse-polarity protected two-wire line.
PAC2200 data can be read out with an M-BUS master. The PAC2200 is then implemented
as an M-BUS slave.
To read out measurement data stored on the device, the slave address must be known.
The user can give a primary address to the device manually, or use the secondary address
of the device. The secondary address is automatically created from the serial number of the
device and must therefore not be set explicitly. Furthermore, the interface of the PAC2200
must be set to the baud rate used in your M-BUS system. Additionally the user can choose
between two different DIF / VIF codes ("mapping"). In "Mapping 1" the measured values are
coded in more detail with DIF / VIF with the result that all the data records have different
coding.
Different measurement data is available, depending on the connection type, 3P4W or 1P2W.
(With MID devices only connection type 3P4W is possible).
The connection type and the parameter setting in the M-BUS communications menu on the
device display define the data record structure or contents of the RSP_UD2 long datagram.
At the M-BUS interface the setting can be determined by means of the version number in the
header of the RSP_UD2 response datagram of an REQ_UD2 request (see M-BUS
specification)

The measurement data is presented on three pages (Mapping 0) and on four pages
(Mapping 1). Multipage-capable masters can read out all three or four pages.
As an example, the coding of the data record with ID 13 (connection type 3P4W, Mapping 1,
i.e. version 32) is more accurately explained in the RSP_UD2 response datagram (see also
