Hello all, I have been doing a project for a bit now, trying to get data from a NOx sensor. Nonetheless, I have tried to initialize the CANbus (SAEJ1939 Protocol) connection, but when I check the voltage for the CAN pins, there is no voltage. It should have 24 Volts so the sensor initializes. I have also connected the sensor and it does not start heating up whatsoever. I have tried other example programs for CANbus that do not use SAEJ1939 with no avail. If anyone could tell me what I am doing wrong I would really appreciate it. I have attached my program and the mentioned pins that have no voltage. Also what does PE (see picture) mean? Thank you!

Hello all. I am very new to PLC programming and I encountered something a bit out of my scope. Recently, I was tasked to create a program that would be able to read the values of a NOX sensor using CANOpen and Visilogic. Currently I am using a SAMBA PLC+HMI SM43-J-R20. The NOx sensor's model is UniNox 24V 5WK96614H by Continental. I followed the example of a webinar online that showed the steps for programming an encoder. I am unsure of how to know which bytes I would need to program to be able to read the sensor information. Such as NOX ppm, oxygen percentage , lambda, etc. The sensor package did not provide an EDS file. Basically, my question would be how to know which bytes I need to extract data from a sensor? And how to program it? I have attached the pages that have the pertinent information and the program I have so far. I would really appreciate any thoughts or comments for this. Thank you.

Hello, i have a JZ20-J-T40 and four 4-20mA pressure sensor´s. I need connect for two 4-20mA sensor´s for 0-10V analog input´s. How it could be done . Can i use 500ohm resistore? Sorry for my bad english.

hello everyone, i got conductivity sensor TetraCon 325, which i connected to monitor LF 296 and its showing some values. I need to connect sensor to PLC modules and show data on PLC screen (V1210).
