hello to everyone,
I will explain you my little project, I have been trying to set up a modbus communication between an RX3I and an HIMA F35 in order to read a coil from the HIMA.
I set in the HIMA F35 Development software, the modbus slave communication configuring some coils as Output Coils.
For what concerns the RX3I, after configuring in the cpu the Standard modbus addressing communication I developed a program that performs the following tasks:
1 open a channel, channel #1 to the HIMA ( 192.168.0.90 )
2 Read the value of a coil from the HIMA.
3 close the channel
I read a guide about configuring this communication but my code does not work.
I listed below 3 links related to my program to allow you to better understand my problem:
