Item Name Type Description Default
13 LossSPComTreat UINT
This variable indicates that the PD-01 will
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.
0x0000
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.
