I started using Unitronics not long ago and I do not have much experience with their hardware/software nor Modbus protocol.
I am using a V570 + optidrive E3 which I have to slower its speed with the program based on an Encoder.
the problem I am having is that sometimes the PLC wont send the instruction for the driver to change its speed. i have noticed from a lot of reasons that it happens because the data wont be transfered.
I am using modbus with RS485 which is already right.
i would like to know if you guys would have any advice or probable solution for it. Could i solve it by changing the baudrate (which is 57,6k).
thank you all!
I have the same problem.
I already did a post last week about this, but no reply on it until now.
I am using the same programm version 1.28.34.
At the alarm summary the list is well right sorted at date/time.
By using the alarm history it seems to be that it is sorted only at time and no date is used.
So it seems to be that it is a bug in the software.
I check at the newest version the upgrade items on the list, but did not find that this isue is solved.
So hopefully Unitronics read this at will fix this bug.
I would ask You for information about reading data from SD card on PLC HMI.
Program is done, costumer demand is to have possibility to record and read a trend (with temperature and pressure data) from every machine cycle. My V700 does it well, and costumer read data from SD on one of HMI screens.
Problem is with preview of trends, because first what i see is oldest recordings and ofc (depend of number of recorded cycles), we need a lot of time to find newest trends.
Is there any system solution for previewing, first from the newest trends (last recorded trend) to oldest?
Thank you in advance,
