Then we will end at %READ_VAR3 for device 4. Then create similar program for each device to read by add compare value to 1 for each command and change %READ_VAR0 to next %READ_VAR1.2.3 and config IndexData for each READ_VARX function block.Д¦. IndexData : First %MW to recieve data (For this block use %MW0 - %MW11 to recieveДҐ.

Quantity : How many data to read (use 12 for P003 - P014) ObjType : Function code that you use (use 0 For Modbus 0x03 for read multiple registers)ДЇirstObj : First Register to be read (For this softstarter start with 0 for P000 then we need to read P003 that means we start with 3) TimeOut : How long to timeout after wait for resplonse Link: Which PLC port to connect with Modbus Device Example I start with %READ_VAR0 for communicate with device slave ID 1. To allow external network access to your DW Spectrum system, there are two. You need to assign %READ_VARX for each communication block. use compare block for %C0.V (Counter 0 Current Value) = 1 when counter reach 1 it will operate then put %READ_VAR function block after it at EXECUTE pin

In this program I have use system clock 100 ms %S5 to count uo conuter for each READ_VAR command for this project I use 4 device to read then I set preset to be 4 + 1 = 5 when counter reach preset it will reset automatically.Д¤. Config Modbus parameter to set PLC as Modbus Master.ДЈ.

Create program on SoMachine or Machine ExpertВ - Basic then assign communication parameter on PLC serial port to match with Soft Starter Parameter.Дў.

I don't have real hardware then I'm not sure that it will work correctly.ДЎ. Hi have create example program for READ_VAR function block attacth to this post
