  • Page 10: Transmission Media For Modbus

    2 Modbus protocol description Transmission media for Modbus Serial interface For data communication via a serial interface, the Modbus specification provides the trans- mission modes RTU mode (Remote Terminal Unit) and ASCII mode (transmission of data in ASCII format). Device type 703571 supports the RTU mode only. Here, the data are transmit- ted via the serial bus in binary format (RS422/485).

    3 Interfaces Location of interfaces Device type 703571 features an interface RS485 (COM 1) as standard. It is designed for trans- mitting data using the Modbus protocol (slave or master) and for connecting an ER8 relay mod- ule. An RS422/485, PROFIBUS-DP, or Ethernet interface are also available for retrofitting in the COM 2 expansion slot.

    3 Interfaces TIP! A twisted connecting cable with shielding must be used to connect the RS422/485 interface; to the greatest extent possible, it should not be laid close to current-carrying components or cables and its shielding should be grounded on one side. To avoid transmission errors, only the signals listed above may be connected.
  • Page 32: Configuring Interfaces

    TIP! Changes to the configuration settings described in this chapter can be made directly on the device or by means of the JUMO PC setup program. TIP! Changing settings in the "Configuration" menu is possible only if a user is logged in with the appropriate user rights.
  • Page 33 3 Interfaces Settings for serial interfaces For all user devices on a bus to be able to communicate with one another, their interface set- tings must match. The table below shows the setting options for the serial interfaces on device type 703571.
  • Page 34 Settings for Ethernet interface A patch/crossover cable with an RJ45 connector is required to use the Ethernet interface.

    4 Modbus via a serial interface Modbus timing for serial interface RS422/485 Device type 703571 features a serial interface RS485 on COM 1 as standard. An RS422/485 can also be retrofitted on expansion slot COM 2. These interfaces can be used to connect the device to up to 2 bus systems. In each bus, one master can access several slaves that are accessible by means of unique device addresses.
  • Page 38: Modbus Master Operation

    4 Modbus via a serial interface Character transmission time The beginning and end of a data block are identified by pauses in transmission. The character transmission time (time to transmit one character) depends on the baud rate and the data for- mat used.
  • Page 39 4 Modbus via a serial interface regardless of whether a process value has changed or not. This rules out a transmission that depends on the condition of a change. The complete frame is always transmitted with the frame length configured in the setup program. TIP! Double writing of a target variable, e.g.
  • Page 40: Modbus Slave Operation

    4 Modbus via a serial interface Modbus slave operation If device type 703571 has been configured as a slave, it responds to Modbus queries from the master on the network. The master controls the data exchange and the slaves only have a re- sponse function.
  • Page 41: Modbus And Other Protocols Over Ethernet

    5 Modbus and other protocols over Ethernet Modbus/TCP protocol Modbus/TCP uses the Ethernet interface for communicating with the Modbus data. The Mod- bus telegrams are transmitted via an Ethernet network (IEEE 802.3) using the TCP protocol of the TCP/IP protocol family. The device type 703571 can assume the role of the slave or master here too.

    5 Modbus and other protocols over Ethernet Networking with Modbus/TCP The image below provides an overview of the networking options when using the Modbus/TCP protocol: Each Modbus/TCP node is accessible via a unique IP address. The "Unit ID" also contained in the protocol (= device address) must be 0xFF for the node directly attached to the network.

  • Page 46: E-Mail (Smtp And Pop3)

    5 Modbus and other protocols over Ethernet E-mail (SMTP and POP3) Device type 703571 can send e-mails (e.g. alarms). In this case, it is the master (client) and can access SMTP servers at the standard port (25) as well as POP3 servers at the standard port (110).
  • Page 47 5 Modbus and other protocols over Ethernet Serves as a gateway between the local company network and the worldwide Internet. It is also used for the conversion of "local" IP addresses (used in the company network) to "one-time" IP addresses (used on the Internet).
  • Page 48 5 Modbus and other protocols over Ethernet Sending an e-mail via the Internet Here, several steps depend on configured device parameters. An error code of the event entry (particularly the error codes 120 to 175) can suggest an incorrectly set parameter. An incorrect- ly entered IP address of the DNS server, for example, generates the error code 153 = "No IP received via DNS".
  • Page 49: User Frames

    6 User frames General information Device type 703571 allows the user to individually compile Modbus frames for his application. This achieves a high level of flexibility and the user can thus reduce the data exchanged on the bus to the volume he requires. This provides a significant advantage with regard to the transmission speed.
  • Page 50 6 User frames TIP! When actively transmitting as a Modbus master, repetitive errors are entered in the event list. Corresponding error codes can be found in Chapter 2.8.3 "Error codes as integer return val- ues", page 24. Error monitoring Each frame is monitored for data transmission. If an error occurs, the corresponding error flag is set, an error code is also stored for each frame, and an entry is written in the event list.

  • Page 52 6 User frames Parameter Selection/settings Description Interface The selection determines whether the frame is actively transmitted as a master or only available for queries as a slave. In the case of a Modbus master, the interface on which the relevant frame is used is also specified. If it is a LAN interface, the external device to be addressed must also be selected.
