Hi,
In FC7, Im using the eblocks CAN and RS232 modules to make a translator for communication between two pieces of kit (see HiUCV FC 7 file attached). The programme works BUT the RS232 messages outputted from the eblock have extra characters attached (see Screenshot), the extra characters being !<SYN>T. Unfortunately these characters mess up the kit receiving the message so I need to remove them. I think they are being added automatically as some sort of synchronisation but have no clue how to resolve / stop them. Please help!!

Regards,
Chris

Hi Chris,
Have you attached the correct project? I don't see any UART or output

Oops... sorry, to many programs on the same project, the attached file is the one with the RS232 stuff!

Hi Chris,
This is probably due to our string concatenation not liking more than two strings.

Could you try changing this ...

Code: Select all

Vmax_serial = "SOUR:VOLT " + ToString$ (Vout_Max) + "\r"

To something like this ...

Code: Select all

Vout_Max_Str = ToString$ (Vout_Max)
Vmax_serial = "SOUR:VOLT " + Vout_Max_Str
Vmax_serial =  Vmax_serial + "\r"

There has been some work in this area recently by our team on V7, so hopefully this won't be needed once the update is released.
