Hi Humphrey,
I have managed to get both SLAVE and MASTER working on the same project.
The Dynamic C library is not complete and ready to go and will require a bit of
work from yourself to get it going. If you are a dab hand at programming you
will figure it out but it will be a bit of work.
If you are doing this over serial, you need to provide the driver for that part.
Same for the TCP/IP version.
I can’t supply any code because of the commercial nature but read the PPP
document as this will guide you.
Once you get going, please feel free to ask questions on what you find.
Dave...

Subject: [rabbit-semi] MODBUS RTU RS232
Hello Fellows, my name is Humphrey. I am completely new into this
I am using a JackRabbit BL1800 and I want to make a serial RS232 comunication
over MODBUS RTU.
I have no idea how to use any of this libraries and specially the one for MODBUS
RTU
Please can any kind soul, could send an example? Or where i can read about
this?
Thanks in advance
Humphrey

Sorry Humphrey, long day. I meant the HEADER files for the libraries.
Try to locate the library file for the LP3500 as this has a lot of the support code for Modbus. I can’t seem to locate it on my system but I know it is installed with the library.

OK. I found them
Check these libraries out as they give you more information about how the code works.
MODBUS_SLAVE_BL26xx.LIB
MODBUS_SLAVE_LP35XX.LIB
They are both in the Modbus library directory. I made my own libraries based on these to suit the exact hardware I was using. My design was also running under UCOS II.
Good luck.
