2. Instructions
This manual is intended to provide instructions for the installation and use of the BDL Compact MODBUS function. The BDL Compact MODBUS function can let the MODBUS client device to read out the online measurement values. This manual is not intended to be a complete tutorial on the MODBUS RTU protocol, and it is assumed the end user already has a general working knowledge of MODBUS RTU Communications, especially in respect of client station configuration and operation. However an overview is included in the following section to explain some of the fundamental aspects of the protocol.

3.3 GeneralModbusInformation
The BDL Compact Modbus module complies with the Modbus serial line protocol [Reference 1]. Among other things this implies a client-server protocol at level 2 of the OSI model. One node (the client) issues explicit commands to one of the ,,server”-nodes and processes responses. server nodes will not transmit data without a request from the client node, and do not communicate with other servers. Modbus is a mono client system, which means that only one client can be connected at the time.

3.3.1 Serialtransmissionmodes(RTU)
The BDL Compact Modbus mode support only one serial transmission modes; the RTU mode. The transmission mode defines the bit contents of message fields transmitted serially on the line. It determines how information is packed into the message fields and decoded.The transmission mode and serial port parameters must be the same for all devices on a Modbus serial line.

Bus cable:
Only cables according to the recommendations of EIA 485 standard should be used. A maximum of 64 devices may be connected to one segment. The bus cable must be laid at a distance of at least 20 cm from other cables. It should be laid in a separate, conductive, and earthed cable trunking. It must be ensured that no potential differences occur between the individual devices on the bus.

Cable specification:
Impedance: Cable capacity: Cable diameter: Cross section: Loop resistance Screening:

For easy Ethernet cable connection to your network an ordinary RJ45 Ethernet cable connection is provided.
Cable: An Ethernet cable with category 5 or better is to be used.

5. ModbusRTUcommunicationsettings
Before communication with the client, baudrate, address, and framing must be defined

5.1 AccessingandchangingModbussettings
First step: Main menu Settings Device settings Modbus settings

The settings are all protected by a password! Inputs and changes have to be confirmed by pressing OK in general!

Enter Password

Factory settings for password at the time of delivery: 0000 (4 times zero).
If required, the password can be changed in the Password settings.
The new password must be entered two times in a row and in each case confirmed with OK.

If an incorrect password is entered there appears Enter password or New password repeat in red font.
If you can’t remember the password, please use Master password in order to enter a new password.
