  1. M2I & Modicon M221 interface

    NoamC posted a topic in HMI & SCADA

    Hello, I have an M2I Top RW (model: 1000WD) connected to a Schneider Modicon M221 PLC. The HMI is connected and I is working perfectly reading data from the PLC via ethernet. I can't seem to find a way to write to the PLC from the HMI. I would like to control the PLC from the HMI, I know this is possible with Fatek PLCs with the same HMI model. please help - how would I create a bit command from the HMI to the PLC? what registers? what inputs in the PLC? thanks
  2. Hi guys, I'm in another project with another brand on PLC and this time I thick I hit a pretty solid wall. Long story short, I need to change a -10 +10v signal send to a DC motor drive based on a "recipe" selected with a 10 positions camswitch. I've never programmed schneider PLC, except the zélio one who are pretty simple to understand. Apparently Modicon are much more complex to program with the knowledge I have. Is there documentation available somewhere I can use to understand how to code analog output.
  3. hi guys i am using my Schneider m221 plc  but facing this below problem. how can write modbus address  i am trying below register data address but not accept this register data  address example i write %MW0:=16#10001 %MW1:=16#10002 %MW2:=16#10003 %MW3:=16#10004 so guys how can write this register address can me  share one example so i understand. also share read var setting . ObjType: FristObj: Quantity: IndexData: Thanks
  4. Hi there, Im having issues controlling ATV 320 VSDs over Modbus RTU with a M221 plc, does anyone have any pointers for me to look at? I believe I Have set everything up correctly but when I run the program on the plc the atv's just stay in 'NST' state I have included screenshots if they are any use   My speed reference in this example is taken from the memory word %MW0 which I am inputting via a HMI   I have addressed all my ATVs accordingly in there setting with the correct Modbus parameters and selected Modbus under the FR1 configuration, am I missing anything?? Any help is appreciated as I am really struggling   Tom
  5. Hello! I am new at PLC programming. I am using TM221CE16R PLC with TM3AI8 analog input module and SoMachine Basic v1.6. I am trying to scale analog input value. I am using 4-20 mA pressure sensor. I managed my wiring so that I get raw values in SoMachine Basic. But I don't know how to scale these values to usable values. My sensor works in range 0 - 16 bar. What is best way to get values? Is it PID function block or multioperand function block using equations to get range 0 - 16? I will appreciate your help.   Thanks in advance!
  6. Hi guys, I have an M221 and trying to read process data from a HACH controller via Modbus 485. In the Read_Var function block I need to configure ObjType, FirstObj, Quantity and IndexData. Slave ID is 3 and I am using SL2. So, say if I wanted to read to following registers, Register #40001, Data Type Integer, Length 1, Description- Sensor Measure Register #40005, Data Type Float, Length 2, Description - Sensor Temp Register #40007, Data Type String, Length 6, Description - Sensor Name what do I put into the Read_Var function ? I am completely new to this and it's just not clear to me. Thanks John   
  7. Hello I would like to connect 2 HMIGXU 5512 to my Modicon M221 is it possible please?
  8. Hello, I got a new work job to design a cycle tester for a mechanism to make sure will work for at least 5000 cycles open - close. I never made a pls program I start researching few days ago and seams to be very complicate to make it. I have a TM221C16R PLC from Schneider. please help me with some instructions. the cycle tester will have a start pushbutton, stop pushbutton, door open switch, one air cylinder with solenoid to push and pull and a counter. Thank you, Romica
