Hey I am new member to this site.
This may be a repeat of a post I sent yesterday, but was unsure
if it made it on to the board. Any way here it is again:
The system is 4 Unitronics V280's 3 are slaves, 1 is the master.
I have talking and sending data between them. This is setup using the
MODBUS UPD over IP just like it shows in the examples.
The problem is, if 1 of slaves goes off line the comminications between the other units stop. I have read the help screens and found this is correct. I have added some handshaking between the units to indicated the communication status between the units and to take the apporate action. This is how I found the
problem.
However this is not what I need. I need the others to continue
sending data. I do not need the other machines(the slaves) to
stop if one is taken out of production.
Can any of you dig into your little bag of tricks and help me
with a work around?? Or am i just stuck due to the nature of this
beast.
According to the help screens the Unitroincs will use MODBUS TCP
over IP, but according to the examples thsi requires a lot of
additional code. It's not desirable but it might be my only
solution.
Let me know your thoughs.
Thanks
AJW
