1.2.3Operating Power
AC/DC Models
These models are supplied with a power cable of 6 ft (2 m) length for operation from
All of these models except the
DC/DC Models
These models operate from a 125 Vdc or 24 Vdc source. ower connects to a terminal strip on the rear panel. A grounding terminal is provided. The dc power source must be fused externally to the B85.
1.2.4Configuration Methods
All B85 models must be configured internally for your application before you can connect them for operation in your application. This is necessary because the B85's internal configuration specifies how each serial port will operate.
Each model has two sets of rear panel switches. ne set assigns the
odbus lus node address. The other set allows you to either configure the unit or set it into its U mode.
Configuring the Modbus Port Models
For the odbus serial port models, you configure the unit locally at a serial terminal connected to one of its ports.
Configuring the Programmable Port Models
For the programmable models, you create an application program externally to the B85 and then download it to the unit across the odbus lus network.
Setting the RUN Mode
hen you have properly completed your configuration of the B85, you can set it into its U mode for operation in your application.
Caution:Do not connect the BM85 into your application environment unless you have set its internal configuration. Do not connect it to your network or to any device unless you have set its switches properly for configuring or running.
