Hi, Sorry. no modbus ASCII. it was ASCII protocol. Slave device accept ASCII protocol Update: ok another question, you've mentioned from yesterday you have error, so you have communication established before with Slave via Modbus ASCII protocol and your CP341? - i have used ascii protocal. with cp-341 it was showing error. ASCII it was working in modbus Poll software Device detail is - TC202a , Manufacture is Thermon AttachmentScreenshots.zip (345 Downloads) |
