Ethernet Port - Siemens SENTRON PAC4200 Manual

Description

3.10 Ethernet port

● Status monitoring: Capturing statuses of connected signal encoders.
● Energy signal for active or reactive energy or freely definable energy types.
A maximum voltage of 30 V can be applied to the digital input. Higher voltages require an
external voltage divider.
Signal input
Either edge or pulse counting.
Data is transferred with the help of weighted pulses or edges, e.g. a parameterizable number
of pulses or edges is transferred per kWh.
The countable unit can be defined separately for each application.
The implementation of the pulse shape corresponds to the IEC 62053-31 standard.
3.10 Ethernet port
SENTRON PAC4200 is equipped with an Ethernet interface. This interface facilitates:
● Configuration of the device using the SENTRON powerconfig software
● Communication between the device and the energy management system
● Device firmware updates
Properties of the Ethernet interface
● Transmission rate 10 / 100 Mbit/s
● RJ45 socket (8P8C) on the top of the device for RJ45 connector with EIA/TIA T568B
assignment
● Cable type 100Base-TX (CAT5)
The Ethernet cable must be grounded for data transmission according to the Fast
Ethernet standard. You can find information on grounding in the "Connecting" chapter.
● Autonegotiation
● MDI-X auto crossover
● Communication over MODBUS TCP
Autonegotiation is a method used by network communication peers to automatically
negotiate the highest possible transmission rate. SENTRON PAC4200 is automatically set to
the transmission rate of the communication peer if the latter does not support
autonegotiation.

NOTICE
Interference with other network nodes due to incorrect network settings
Incorrect network settings can adversely affect or interfere with the functions of other
network nodes The network settings for Ethernet are defined by the system
administrator and must be set accordingly on the device.
If the settings are not known, the (patch) cable must not be connected.
