Technical support / Re:Modbus RTU
« on: January 03, 2009, 08:17:13 PM »
This is the situation now.
I have the T100MD connected to the VFD.
I have setup a function (1st scan) to change the port #3 to 19,200 8,2,n (setbaud 3,14) to match the VFD.
I have another dCfn to read the parameter 105
DM[1]=READMODBUS (13,1,105).
I change the ID=2 on the PLC, the VFD ID=1.
I am suppose to receive 50 on DM[1], i have no answer from the VFD.
I disconnect the cable from the VFD, if I check the voltage on the plc port is 2.1v and when the function is activated, the voltage change to -1.5v and go back to 2.1v. That may show that the port is sending the signal, I don't know.
On the VFD cable I have 2.57v (disconnected from the PLC). When I connect the VFD to PLC port, the voltage is 2.4 and also when the function is activated, the voltage changes.
What am i doing wrong and have no communication?

Thanks,
Philip

Does the plc transfer any value to the parameter?
Example: Parameter 1.14 use text strings intead numbers and I want to write on it A1.A2 via Modbus RTU.
A="A1.A2"
WRITEMODBUS (13,02,A)
Will that work?

Thanks,
Philip

Hi,
I am looking on some help to get comunication between a T100MD+ and a Control Techniques VFD thru Modbus RTU.
The VFD support functions 03,06,16,23 and 40.
If parameter on VFD Pr 1.02 = 40102 (MODBUS PLC register) = 101 (Register address), what will be the format to read/write to/from that parameter?

Thanks.

Do you have any DC or AC drive to control the speed?
What are the input that the drive have (DI,DO,Comunication-RS232,RS485)?

If you have a drive you can start thinking about control the speed of a motor.

General Discussions / Barcode Printer
« on: December 23, 2002, 12:26:11 PM »
Does anyone know where can I find a barcode printer with RS485 connection and ID?

I have some PlC's connected through a network, but I need generate barcode at diferent places. I cann't connect the barcode printer to every PLC, because I have 4 PLC and I need 10 or more barcodes. I know that the TX PLC's have 2 RS232, but if I use them, that mean that I need one PLC for every 2 barcode printers.

Hi, I'd like to install a bar code scanner to a t100md1616 and save that code to a data memory DM's.

Where do I  need to install it?
How should I program that input?
What are the better models and manufactures that work properly with this plc?
