That's great SoCold,
Everyone's done such a thing in missing a "typo" during programming.
That important document you spend hours on proof reading till it's perfect? A minute after you send it you notice another error!
Hi everyone, i'm new here, i'm working with plc, but i have unitronics usp-104-b10 on my desk up to now. unilogic version: 1.28.34
I need to solve crc checkum rs485 specific protocol of one noname thermostat. I tried it through message composer but it failed. Thermostat works, I tested it with com debug, connection is ok.
Checksum definition: checksum = (header + command + id1 + id1 + data0 + data1 + data2 + data3) and FF xor 3C
example: # H30 = (# H0B + # H00 + # H01 + # H00 + # H00 + # H00 + # H00 + # H00) & #HFF xor # H3C
it should look like this: txBuffer = 0B 00 01 00 00 00 00 00 30 do you have any idea how to solve it?
I have this software, it uses the same connection as the port RS485 but the software communicates via RS232.
I want to modify the speed of the motor with the samba with RS485.In fact I have a machine with two of this servo driver and the speed is a value used for the good functioning of the machine.
The operation must be this one : someone writes the speed on the HMI of SAMBA and SAMBA modifies the speed of the driver.
