 Parity Bit, Data Bit, Stop Bit can set at AB SLC PLC Ladder program.

 

  AB-SLC Serial communication driver’s read schedule

Read schedule setting parameters are as follows:

1) STATION – station = 0 ~ 255.

station no. of peer to peer connection = don't care.(0, or etc)

2) memory type(and file number) – memory type = O0, I1, S2, B3, T4, C5, R6, N7, F8, …

File Number 9 ~ 255  : B, T, C, R, N, F (setting by Ladder program)

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. 

T, C, N  : 1 ~ 119 WORD,

F  : 1 ~ 59  Float(double WORD).

  When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.

 

 

2. Writing settings

You can write AB SLC PLC by writing settings.

 

 

Bit Write

Bit write setting parameters are as follows:

1)  PORT  :  Port no. (0 ~ 255)

2) STATION :  station = 0 ~ 255.

station no. of peer to peer connection = don't care.(0, or etc)

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 =O0, S2, B3, T4, C5, R6, N7, …

5) EXTRA 2 : R, T, C memory =  0 – status bit, 1 – setting value, 2 – count value,

Other memory  = Don;t care.

 

 

 

Write example 1)

PORT : 0   STATION : 1   ADDRESS : 002F  EXTRA1 : B3  EXTRA2 :

The setting parameter shown above is an example of bit write for 2 word, F bit of memory B3 for AB-SLC PLC connected with 0 port, 1 station.
