Device part of <Figure 1> input Com Port(COM8), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to setting of controller.
Wizit Dongdo Calorimeter communication driver read schedule
Read schedule setting parameters are as follows:
1) Station Address – 0 ~ 255 station Address.
2) Read command – command = fixed to CURR.
3) Read start address – don't care.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – fixed to 1. ( refer to <table 1> )
Read schedule example)
READ, 1, CURR, 0, 0, 1,
<Table 1> is data saving address and contents for CURR read command.
| Data saving address | Contents | Remarks |
| start add + 0 | error status | 8 = normal, 40 = error |
| start add + 1 | status | |
| start add + 2 | status value for sum calori data | refer to <Table 2> |
| start add + 3 | sum calori value | float, double unit |
| start add + 4 | status value for current calori data | refer to <Table 2> |
| start add + 5 | current calori value | float, double unit |
| start add + 6 | status value for sum flow rate data | refer to <Table 2> |
| start add + 7 | sum flow rate value | float, double unit |
| start add + 8 | status value for current flow rate data | refer to <Table 2> |
| start add + 9 | current flow rate value | float, double unit |
| start add + 10 | status value for supply temperature | refer to <Table 2> |
| start add + 11 | supply temperature | float, double unit |
| start add + 12 | status value for recovery temperature | refer to <Table 2> |
| start add + 13 | recovery temperature | float, double unit |
| start add + 14 | status value for supply pressure | refer to <Table 2> |
| start add + 15 | supply pressure | float, double unit |
| <Talbe 1> Data saving address and contents for CURR read command | ||
| bit position | Contents |
| bit 0 ~ 7 | data type : 0 = calori, 1 = flow rate, 2 = supply temperature, 3 = recovery temperature, 4 = pressure, 5 = etc |
| bit 8 | Off = sum value, On = current |
| bit 9 ~ F | don't use |
| <Talbe 2> Each bit data for status value | |
Wizit Dongdo Calorimeter communication driver store the same data in WORD, DWORD, FLOAT, DOUBLE memory, but the data formats are different.
If you click the icon
