Page 9: Mounting And Installation
Haiwell PLC - Load Cell Module Application Example 10. Mounting and Installation The PLC should be secured to an enclosed cabinet while mounting. For heat dissipation, make sure to provide a minimum clearance of 50mm between the unit and all sides of the cabinet. -

(This case happens when the number of expansion Modules is too big and external loads are too much). Haiwell extension Module can be used as remote IO, so it will not be restricted by the number of system I/O points, and can be installed distributively, reducing cable wiring and solving the problem of interference caused by the long distance of traditional wiring. -
Page 11: Hardware Configuration
Haiwell PLC - Load Cell Module Application Example The second step: Read the weight. One is average weight and the other is real-time weight. We usually read average weight. The third step: Adjust the stability and responsiveness of weighing. The above two factors affect the sampling frequency, average number and filtering rate. - Page 12 Haiwell PLC - Load Cell Module Application Example An example of 32-bit multi-segment calibration program is as follows: 12 /...

Page 13: Read Average-Weight And Real-Time Weight
Haiwell PLC - Load Cell Module Application Example 6. Read the current weight The weight read by module is divided into average weight and real-time weight. Usually we read average weight. The average weight CR of 16 bits is 10H, and the real-time weight CR of 16 bits is 12H. The program example is shown below. -
Page 14: Adjustment For Weighing Stability And Response Speed
Haiwell PLC - Load Cell Module Application Example The average weight CR of 32 bits is 16-17 H, and the real-time weight CR of 32 bits is 14-15 H. The sample program is as follows. 7. Adjustment of stability and responsiveness of weighing value The stability and responsiveness of the weight read by the module will be adjusted according to different requirements in practical applications. - Page 15 Haiwell PLC - Load Cell Module Application Example 1FH: Filtering Ratio The larger the register value is, the larger the filtering ratio is, the more stable the average weight value (10H), but the delay will increase and the sensitivity will decrease. The function of filtering is to filter the abrupt change so that the average value of the filter can not be affected by the abrupt change.

When the value of 25H is written to 1 and the weight value is 16-bit display, the current 16-bit weight value (10H) is read as the weight value of the leather weight, and the weight value is read as the weight value of the leather weight;... -
Page 17: Automatic Peeling 2Ah (Judge Every 5S)
Haiwell PLC - Load Cell Module Application Example 9.Automatic peeling 2DH (judged every 5S) The weighing platform or equipment will cause dust or residue scattering during weighing process, which will cause the platform to peel automatically when the current weight is not zero without placing any weighing items. If the automatic peeling function is used, as long as the current weight is less than the set automatic peeling weight 2DH value, the weighing module will peel automatically the current value. -

Haiwell extension Module has a RS485 communication port (part models with additional Ethernet communication interface), which supports parallel bus (the parallel interface with PLC host by extending the extension bus) and the serial bus (using the RS485 communication port with the communication port of the PLC, the host plc using the communication instruction to control the remote Module). -

①It can be configured by programming software tool remote Module (recommended). ②The Module can be connected to the host plc by parallel port and configured by hardware configuration and TO instruction. ③The Module can be configured by MODW instruction through serial communication 5.Parameter configuration example: configuring the Module through programming software “remote Module tool”. - Page 20 The default address of the Module is 1 with format 19200, N 82 RTU, and the online success is as follows: If there is only one plc on the 485 port, then you can use “find standalone”. If there are many, set the start address and stop address, so that all the machines on the 485 port can be found and the parameters are configured.

①:hardware wiring: the 485 ports of the host PLC and the load Cell Module are connected by the shielded twisted cable and the A+ is connected by A+ and B- to B-. If PLC connects to multiple weighing Modules, it is necessary to connect by mode of “hand by hand”. - Page 22 Haiwell PLC - Load Cell Module Application Example Step4: If the second calibration is needed, add another standard weight to the weighing unit, and write the weight on the current chassis into CR29H, otherwise Step6 will be executed. Step5: If the calibration of paragraph 3 is required, add another standard weight to the weighing unit, and write the weight on the current chassis into CR2AH, otherwise Step6 will be executed.
