AB-PLC5 TCP communication driver’s read schedule
Read schedule setting parameters are as follows:
1) STATION – Don't care(fixed to 0).
2) memory type(and file number) – memory type = B3, N7, F8, N9, N17 ...
3) Read Start Address – read start address of memory.
4) Save Start Address for Communication Server – save start address.
5) Read Size – word unit size.
Read schedule example)
READ, 0, N7, 0, 0, 10,
READ, 0, B3, 0, 10, 10,
FLOAT, 0, F8, 0, 0, 1,
FLOAT, 0, F8, 1, 1, 1,
FLOAT, 0, F8, 2, 2, 10,
FLOAT, 0, F8, 35, 35, 10,
You can write AB-PLC5 by writing settings.
Bit Write
Bit write setting parameters are as follows:
1) PORT : Port no. (0 ~ 255)
2) STATION : Don't care.
3) ADDRESS : Upper 3 digit = word unit writing address (10 digit), Lower 1 digit = 0 ~ F(16 digit) writing bit pos.. (ex : 001A = 1 word A bit)
4) EXTRA 1 : Memory type = B3, N7...
5) EXTRA 2 : Don't care.
Write example 1)
PORT:0 STATION:1 ADDRESS:0003 EXTRA1:N7 EXTRA2 :
The setting parameter shown above is an example of bit write for 0 word, 3 bit of memory N7 for AB-PLC5 connected with 0 port.
Word Write
Word write setting parameters are as follows:
1) PORT : Port no. (0 ~ 255)
2) STATION : Don't care.
3) ADDRESS : 10 digit word unit writing address. (ex : 0010 = 10 word address)
4) EXTRA 1 : memory type = N7, N10.
5) EXTRA 2 : Don't care.
Write example 1)
PORT:0 STATION:1 ADDRESS:0015 EXTRA1:N10 EXTRA2 :
The setting parameter shown above is an example of word write for 15 word of memory N10 for AB-PLC5 connected with 0 port.
