  • Page 65: Linearization

    Linearization Conveyor applications where the ideal belt scale location has been compromised, or where there is a high degree of variation in belt tension, typically cause the belt scale to report load non-linearly. The BW500 and BW500/L provides a linearizing function (P390 - P392) to correct for the deficiency in the weighing system and to provide an accurate report of the actual process.

  • Page 69: Operation

    Operation Load Sensing For the BW500 and BW500/L to calculate rate and totalize material flow along the belt conveyor, a load signal representative of weight of material on the belt is required. The load signal is provided by the belt scale. The BW500 and BW500/L is compatible with belt scales fitted with 1, 2, 4, or 6 strain gauge type load cells.

    Example: Setting P398-02 = 30% will allow the 4 - 20 mA input to correspond to 0 - 30% moisture. The Zero and Span calibration is not affected by the presence of a moisture meter. It is understood that the calibrations are performed using dry static weights.

    The mA output value can be tested to output a prescribed value using parameter P911. P911 Refer to on page 145. The optional mA I/O board provides two additional mA outputs , programmable as outputs 2 and 3, using the same parameters as the standard output (1). If programmed for PID control, output 2 is assigned to PID control loop 1 and output 3 is assigned to PID control loop 2.

    PID Control The PID control algorithm in the BW500 is designed specifically to work for feed rate control applications. It is based on motor control type algorithms and includes several anti-wind up provisions. One way to prevent wind up is to monitor the input speed frequency from the weighfeeder.

    The control output cannot reach the setpoint using only the term. Since the term acts on the difference between the setpoint and process variable, a small difference between these two always exist and the difference is never zero. A small term can get the process very close to set point, but it would take a very long time.

  • Page 89: Batching

    Batching The batching process, as it relates to the BW500 operation, can be defined as the transfer of a predetermined quantity of material. The process supports a count up operation (P560), in that the total (totalizer 5) begins at zero and increments up to the programmed setpoint (P564). A relay (RL1 through 5) programmed as the batch setpoint function (P100 = 8) is actuated when the material total reaches the setpoint.

    Operation Once the BW500 relays are connected to the process logic, and it is programmed, the BW500 is ready for totalizing the batch and stopping the process when the batch setpoint is reached. The batch operation: start, pause, resume, and cancel are controlled externally by the process control (e.g.

  • Page 101: Modbus Rtu Vs. Ascii

    Modbus RTU vs. ASCII There are two main differences between Modbus RTU and Modbus ASCII. The first is that Modbus RTU encodes the message in 8-bit binary, while ASCII encodes the message in ASCII characters. Therefore, one byte of information would be encoded into 8 bits for RTU and into two ASCII characters for ASCII (which would be two 7-bit units).
