Hi guys, I'm a beginner in the PLC world and i would like some advices because i'm stuck in my program with the temperature controller.
I work on TIA portal V13, CPU 1217C DC/DC/DC, i have a CM 1241 RS485 module and the temperature controller is a DTE-10-T from DELTA.
I have tried the function block MB_COMM_LOAD with MB_MASTER to write/read data on the controller but when i try to read something it always fail and when i write something the led of the controller is flashing i guess the link is working but maybe i miss some parameters or character in the variable i use to read data.
The string i send to read max value is ':010310100002' and it does nothing :/
but when i try to write with ':010610100300' to put 300 ° on max value the led of the controller flash a little bit
Here is the doc of the temperature controller : https://www.automation.siemens.com/...ttachment.aspx?attachmentID=49595&Language=en
in MB_COMM_LOAD i have set : 2400 baud rate, parity none, 7 bits ..
if someone have an idea i'll be grateful
