PD-01 PROFIBUS-DP Module
Item | Name | Type | | Description | Default |
13 | LossSPComTreat | UINT | This variable indicates that the PD-01 will | 0x0000 |
| | | take action when the SP communication | |
| | | (SCANport communication) is lost, the value | |
| | | can be assigned as follows: | |
| | | 00 | – Stop data exchange and report fault; | |
| | | 01 | – Continue data exchange and report | |
| | | | alarm; | |
| | | 02 | – Ignore and continue data exchange. | |
If the address in Data Output 1 ~ Data Output 4 is continuous, then set d_state to 1, PD-01 will get starting address from Data Output 1. The next data will be got from the address next to the starting address, and the reading length is determined by dout_len. If the MODBUS address for reading is discontinuous, please set d_state to 0, PD-01 will also get starting address from Data Output 1, but the difference is the other data will be got from the address saved in Data Output 2, Data Output 3 and Data Output 4 in order.
Example, if | |
Data Output 1 | = 0x2100; |
Data Output 2 | = 0x2101; |
Data Output 3 | = 0x2102; |
Data Output 4 | = 0x2103; |
dout_len = 0x0003;
The MODBUS address in Data Output 1~Data Output 4 is continuous, so you can set the d_state to 1, then PD-01 will monitor the address starting from Data Output 1, and monitor 3 words from VFD series Drives one time. When the dout_len is 3, PD-01 will ignore the address in Data Output 4. If d_state is set to 0, PD-01 will read data from the address in Data Output 1, and read data from the address in Data Output 2, and so forth.
