error occurred during controlling PLC using Modbus

[RyanFan]

Hi

I'd like to control a motor via PLC using Labview modbus, i can control the motor to rotate while given a certain parameters (angle), but when i want to read the angle of motor during the motor rotation, there will be an error. i also tried reading the angle motor separately, and it works.  could any guys help me?

thanks.

Thanks for your reply.

i think the problem you mentioned in the post is he has two slaves, but i only have one. i try to clean the specific error which i get during test, up to now, it works, but i am not sure it's the right way to solve the problem.

thanks again.
