I didn’t understand about this formula. I have tried this in output channel, but the server is showing error.
Trailing image for your reference.
Kindly help me how can i convert the standard command to byte.
I understand that coil is only one bit. But the device which i bought was using two register for coil. I have already sent you image in the first post that i have turned ON a coil by assigning it as UINT.
This device modbus request is not as per standard modbus commands(Only for output coil).
How can i do this in Rapidscada ??
I have followed the entire procedure same. I succeed in reading and writing holding registers which are specified in register map. I also able to read the status of digital inputs and digital outputs. I can force the multiple digital outputs from available holding register provided in manual by sending the command 1 to turn on output 1 or 4 to turn on input 5, but this is not feasible for me. So i would like to TURN ON one coil at at time just by sending decimal 01 to the register.
But the problem is that in order to force on one digital input at a time, i have to declare the coil type as unsigned int instead of bool and have to send 00 01 command instead of FF 00 to TURN ON.
If i declare as holding register in command properties then the communicator will send the command the as 02 06 00 00 00 01 48 39 (since device address is 02 and function code of write holding register is 06)
I would like to send the command with function code – 05 and want to declare the register as 02 bytes uint. Kindly help how can i achieve this.
Trailing image for your reference, i have declared command as holding register and it is sending command as function code 06. I have clearly shown you the image in the previous post that i would like to send the command as 02 05 00 00 00 01 along with CRC.
Waiting for your help.
Please find the link for the image in which i have assigned command. But element type was disabled and was not unable to modify it.
I would like to set the element type or data type as Unsigned Int (2 bytes). Kindly help how can i set that.
Trailing image in which i have written output coil by assigning coil as 16bit unsigned int. Kindly verify this too.
It was unblocked successfully in windows explorer and i was able to use it.
Thanks for your support.
Right click was not able to do. I have activated it, but showing the error as stated earlier.
It worked Now.
Device was not responded, since i have assigned the Holding registers(one register – 02 bytes) as Unsigned(16) initially. Later on changing them all to Signed(16), it worked well.
Serial connection was good, since it worked with other Modbus Master software.
Thanks for your immediate response.
I have downloaded meters image pack from rapid scada website and started using them. I have given the input channel to the meter, but unable to find the object in the bottom which was default assigned to channel 843.
Version of webstation is 126.96.36.199 and version of chartpro plug in is 188.8.131.52. But version of charts and schemes plugins was 184.108.40.206
Yes i have started the addres from 3020 to 3021 and it worked. thanks for your valuable reply.
