Hi new to the forum, and first post, however, I have found an abundance of great information here, so I was hoping someone might able to help me with an issue. PLC is BRX BX-DME1-10ED13-D I am trying to read an analog output from a sensor that is capable of essentially outputting a mA signal proportional to where a printed line, or contrasting edge is at in its field of view. It is used for web guiding applications to make sure the web is tracking straight, so you can identify if the line or edge is moving to one direction or the other, and correct the web with an articulating web guide. I have attached the diagram for the sensor, but I cannot for the life of me figure out 2 things 1) The power supply to the sensor is listed as follows Supply current - From fife control +/- 12vdc 50ma (+)12vdc AND - 40ma (- )12vdc how do you provide both (+) and( -) 12VDC for the supply power to a sensor- 2 power supplies with the the opposite polarities grounded on each? 2) The outputs are listed as "Sum" and "Differential" so apparently there are two outputs, i dont know if anyone has come across these terms relative to sensors before, but I am trying to sort these out. According to the OEM Sensor Output Range -20 mA to +20 mA for line guiding -20 mA to +10 mA for edge Guiding I have attached the pin out diagram as well as the sensor spec sheet, but I am curious to see if anyone might have insight as to how I would get an analog input reading from this configuration? Thank you in advance for any help! 224615.pdf SE-26B Product Sheet.pdf
Hi to everyone, i'm a junior programmer. My boss told me that i have to study a new plc: BeckHoff. I ask you if somewhere there is a guide about this plc, and about ST language used in this plc. I tried to use the help function on TwinCAT 2, but it doesn't explain lot of things. Before that, i used to program with ladder language, so i don't know nothing about ST. I hope in one of your help.
I have restored a crashed IFIX to a new PC. The restore is ok and installed GE9 driver. With the GE9 power tools, we can observed that data transmits and recieve. The problem is that the screen scada is not updating i.e. no status/feedback, anything is happening. The LAN network TCP/IP was configured i.e. IP, subnet and gateway. Any remedies/advice is most welcome. Please provide a guide on the communication/configuration setup. Thanks
