#151861 - RTU Communication is working! Responding to: ???'s previous message |
Hi guys,
Finally the communication for RTU is working. I spotted I put a 100ms delay during polling of RTU slave reply. It cause the uC processing routine is too long which cause the RTU string not being processed. Till then, thanks for your great helps and support. Chin Liang |
