No response from the slave


Thread Starter


We are writing a programme to communicate Through RS485 using modbus protocol. Although we seem to getting output (as viewed on CRO) accross data lines of RS485, we are not getting any response from the slave. Slave is a temp controller manufactured by Brainchild Electronics Co. Ltd, Taiwan.

Do you have a driver written in VC++ which can be downloaded by us and used. We need the source code to incorporate into our programme.

Thanks in anticipation
