Hello Everybody I am trying to use Proview with some Modbus RTU devices, using Modbus_RTU_Master, Modbus_RTU_Slave and

Modbus_RTU_Module.

I put all these object in NodeHier but I am new on that, can somebody help me?

I'm going to communicate with Siemens PLC to get five Hexadecimal value.

They include two velocity values, one pendulum length, and two enabling signals.

But I wonder how to get the data from PLC and assign it to the variables in PlcProgram.

H2-Av1 and H2-Av3 is velocity values,H2-Av2 and H2-Av4 is pendulum length,H2-

Dv1 and H2-Dv2 is enabling signals in PlcProgram.

After calculation, the value is returned to PLC.

They include H2-Av1、H2-Av3、H2-Av7.

Can you show me step by step!


Thanks!

Hi Qinliang,
To connect Channels ($Node) to plc variables ($Plant) use Di, Do, Ai or Ao objects instead to Av or Dv objects.
See Documentation, my tutorial video N°7 (part2) at 24min : how to connect ChannelDI with DI object.
Note: use "ctrl" + double-clic to asign the selected ChanDi, ChanAi,... to the corresponding plc variables.
