I am monitoring half duplex communication by LE-7000. I cannot receive data because of some problems in RS-485 line-control. There is two types of non-communication state, 0 and 1.
You need to control a control-line to make Drives to be non-active. Please follow the below instructions in the "Program Simulation".
Make a control-line to be active to control Drives.
- Transmit data.
- Leave it for a while.
- Make a control-line to be non-active to control Drives.
