Operating Instructions BW500 and BW500/L

Application

Milltronics BW500 and BW500/L operate with a belt scale and a speed sensor. Belt load and speed signals are processed for accurate flow rate and totalized weight of bulk solids.

BW500 can take on lower level control functions traditionally handled by other devices, and it supports popular industrial communication buses. Its proven load cell balance function eliminates matching of load cells.

The PID function may be used for rate control on shearing weighfeeders - where belt loading is constant - but can also control pre-feeding devices. Operating in tandem with two or more weighfeeders, the BW500 may be used for ratio blending and controlling additives. Batching, load out, and alarm functions are also provided by the BW500.

Benefits

Automatic zero and electronic span calibration
Alarms for rate, load, speed, or diagnostic error
On-board Modbus and optional: PROFIBUS DP, Modbus TCP/IP, PROFINET, EtherNet/IP, and DeviceNet
Comprehensive weighfeeder control functions
PID control and on-line calibration with optional analog I/O card
Differential speed detection with second speed sensor
Moisture meter input with optional analog I/O card for calculation of dry weight
Inclinometer input with optional analog I/O card to compensate for conveyor slope
Suitable for belt scale custody approval
Measurement Canada, OIML, MID, PAC Russia, and NTEP approved

SmartLinx Module

The SmartLinx modules offer seamless digital connectivity to widely used industrial communication buses, ensuring straightforward plug-and-play compatibility with Siemens-manufactured products. This facilitates easier integration and interoperability within industrial setups.

Operating Instructions SmartLinx Modules

Operating Instructions LVDT CONDITIONER CARD

Application

With the addition of a SmartLinx module, Siemens instruments can be connected to a variety of industrial communications networks.

They’re fast and easy to install, and can be added at any time. The module simply plugs into the socket on any SmartLinx enabled product. They require no secondary private buses or gateways and no separate wiring. There are no extra boxes to connect to your network so there’s a minimum load on engineering and maintenance staff.

SmartLinx provides all data from the instrument, including measurement and status, and allows changes to operation parameters to be done over the bus or telemetry link. The user can select which data in the application layer to transfer over the bus. This selection saves bandwidth and memory and optimizes data throughput and speeds up the network, enabling you to connect more instruments to your network.

Selecting a communications module: PROFIBUS DP-V0 versus PROFIBUS DP-V1

The PROFIBUS DP-V1 card was added to MultiRanger 200 HMI and HydroRanger 200 HMI to provide acyclic communication and SIMATIC PDM support over PROFIBUS and PROFINET. For backward compatibility, the PROFIBUS DP-V0 card can also be used with MultiRanger 200 HMI and HydroRanger 200 HMI.

MultiRanger 100/200, HydroRanger 200, BW500/L, and SF500 are compatible only with the PROFIBUS DP-V0 module.

Benefits

Fast, easy installation
Direct connection: no additional installation required
Scaleable application layer allows for optimized network bandwidth and memory requirements (for PROFIBUS DP-V0 and DeviceNet only)
Modules available for PROFIBUS DP-V0, PROFIBUS DP-V1, PROFINET, DeviceNet, Modbus TCP/IP, and EtherNet/IP
