I need to write a C code for our communication board to control a Temperature
Chamber with Watlow F4 Controller. Watlow F4 uses MODBUS protocol. Then,
through RS485 it is controlled by our software implemented in our computer:
Computer <--RS485---> Communication Board <-- RS232 --> Chamber.
(software) ( write new C code ??) (MODBUS)
The C code will be flashed in the EPROM in our MCS251-based Communication
board.
I am new to MODBUS and need some suggestions and source code examples.
I really appreciate your great help.
