Hello Duris_I I've tried all different settings for the communication and the only one that appears to work is that in my previous post. I have attached the Data sheet for the PM sensor I'm trying to use. Richard AttachmentPMS1003 series data manua_English_V2.5 .pdf (345 Downloads) |

Hello, uuuuuh I see same system as we expected but poor documentation in my opinion. In this case I'll recommend instead of your PLC connect PC with some Serial application which can send/receive to serial port, maybe also standard Hyperterminal can be used. Connect to device via suitable converter and look to received messages. Really now probably no other way how to correctly investigate that message structure for sure, now simply you can't believe now to PLC. Pls try that and give us info. Also you can look to this topic: https://www.dfrobot.com/wiki/index.php/PM2.5_laser_dust_sensor_SKU:SEN0177 |
With best regards... |
