Communication 11 Communication All devices are equipped with an Ethernet interface with an RJ45 socket. Other communication interfaces can also be available optionally. – RS-485 – PROFINET – EtherNet/IP™ 11.1 Ethernet All device versions are Ethernet-capable via an RJ45 interface. The devices support 10/100 Mbit full/half duplex. It is recommended to use at least Cat.5 cables (EIA/TIA-568) for installation. 11.1.
EMpro - multi-functional energy measuring devices for front panel installation 11.1.2 Configuration of the communication interface You can adapt the following parameters of the network interface: Table 11-2 Adaptable parameters of the network interface Function Information Web server Display Register Mode The mode is used to define whether a static IP configuration from the device memory has to be used, or a dynamic configuration should be performed via DHCP instead.

EMpro - multi-functional energy measuring devices for front panel installation 11.2.2 Modbus/RTU In the case of Modbus/RTU, the Modbus application layer protocol is supplemented with additional information and physically sent via an RS-485 interface. The start and end of a Modbus message is coordinated by means of timings. Modbus/RTU describes a master/slave protocol. Here, the EMpro acts as Modbus/RTU slave. An exception here is the gateway mode.
Communication 11.2.2.2 Using connections and designations Internal GND BΩ A+ Ω Figure 11-2 Connections and designations The RS-485 interface has four assigned terminals.

Communication Figure 11-4 Modbus settings Please observe the following: – Each slave is assigned an address between 1 and 247. – Each address is used only once. – There is only one master per RS-485 network. – All devices use the same parameters for the baud rate, stop bits and parity.
EMpro - multi-functional energy measuring devices for front panel installation 11.2.3 Modbus/TCP In the case of Modbus/TCP, a special header (Modbus Application Header [MBAP]) is prefixed to the Modbus message. This Modbus/TCP message is then transmitted via an IPbased network in a TCP frame. The EMpro acts as Modbus/TCP server and opens port 502 for communication with any Modbus/TCP clients. This port cannot be configured by the user.
Communication The following questions regarding the behavior of a gateway remain open: – Forwarding the broadcast in the RTU network. Since there is no broadcast in the case of Modbus/TCP, it is not defined whether or not the MBAP address 0 is forwarded in the RTU network by the Modbus gateway. – Response messages with the unit identifier 0. Neither is there a definition on whether the gateway itself generates an answer to messages with a unit identifier of 0.

EMpro - multi-functional energy measuring devices for front panel installation R: Register The “R” stands for Register and designates the lines that each describe a register. Only lines that also contain registers are relevant for automatic processing of the register table. U: Unused The “U” describes unused entries. These can be, e.g., address ranges that do not have a function (yet) and are reserved. E: End The “E” describes the end of the table.
Communication R/W: Read and write It is possible to both read and write to these registers. W: Write only These registers can only be written. Attempting read access to these registers causes an error. W/R0: Write only and read 0 These registers can only be written. Read access to these registers results in a zero as response. Datatype This column contains the data type to be used for decoding the contents of each respective register. ASCII Each register (16 Bit) contains two ASCII characters.
