3.4 Modbus Port Parameters 3.4.1 Information You Will Need You will need the following information for each port that you will use in your application. Parameters are explained in the sections indicated. Port Type (see Section 3.4.2) Modbus Master Modbus Slave Modbus Network Modbus `Silent Master' Network Slave Device Address (see Section 3.4.3) 1 ... 247 Communication Parameters (see Section 3.4.4) Baud Rate: 50 ...

PAGE 41
3.4.3 Slave Device Address If the port is to be configured as a Modbus single slave device port, a slave device address must be assigned to the port in the range 1 ... 247 decimal. The address is part of the configuration of a port to which a single slave device is attached. This address is not applicable to Modbus master devices, as they do not use a device address. It is also not applicable to Modbus networked devices, as multiple devices can exist on the port. 3.4.

3.8.2 Using the V1 Screen Select the port you want to configure. For example, enter P4 to select Port 4 and make it the active port. Your currently selected port is shown on the bottom line of the screen. Specify the port type by entering T with one of the following types: M (Master), S (Slave), N (Network), or X (Silent Master). For example, enter TS to setup the currently active port as a slave port. A Silent Master port will be labeled `xmaster' on the screen.

4.2 Required Equipment 4.2.1 Equipment for Writing the Application Program First, you must create your BM85 application program. For this you will need the BM85 Program Development Software Tool Kit. Part numbers and ordering information are provided in the BM85 Section 1.7.2. For compatibility with the BM85 development software, your PC hardware should be an MS-DOS compatible platform with at least 4 Megabytes of RAM. You will also need the Borland Cā/āC++ compiler at version 3.

4.4 Installing the Development Software This overview of the software installation process is supplied to assist your planning. Complete documentation is provided in the software kit. Substitute the paths and parameters used in your Borland development environment wherever applicable. 4.4.1 Default Parameters The development software is supplied with two default parameters for downloading to your BM85.
PAGE 73
Start your Borland compiler development environment as described in your compiler documentation. Update the BM85 Project file BM85.PRJ to set the correct directory paths for your Borland environment. For example, in the Borland 3.1 environment, you can use the following key sequence: Key Sequence Purpose Alt–P Project open BM85.

5.2 Connecting the Power Cables See Sections 1.6 and 1.7 for details about the BM85 operating power and connector requirements. Caution:ąYou can connect power cables to the BM85, but ensure that the power is OFF before connecting the network or serial cables to the unit. AC/DC Models AC/DC models are supplied with a power cable of 6 ft (2 m) length for operation from 110-120 Vac or 220-240 Vac single-phase power. The cable connects to a socket on the rear panel. Grounding is through the cable.
