The code of this project also works with CJ2M-CPU34, using the peripheral port (USB). The response of this PLC has some fields different, but the value of memory is in the same position.   Jorge

Hi @gclshortt, thank you for the reply!   I was studying the code of this project and I changed it to read the memory. Now, it works fine with CP1E too  :)   But I still do not understand some message fields... In the next week, I will test the code with CJ2M, also have the USB port. The serial port is busy and I just have the USB port free to read counters (in DM)    Best regards, Jorge    

Hi, this is my first post in Mr.PLC :) In CP1E-N20 I can send c-mode commands to RS232c port to access the memory. The access memory through the USB port is possible? And What is the protocol?    I find a project in https://program-plc.blogspot.com/2015/12/omron-plc-usb-protocol-used-for.html to CP1L-L10 When I send to CP1E the "PLC_Run_Mode" = [AB,0,11,80,0,2,0,0,0,0,0,0,69,4,1,FF,FF,4,3,AE], I should get  [AB,0,10,C0,0,2,0,0,FB,0,0,0,4,1,0,0] but I receive [AB,0,10,C0,0,2,0,0,0,0,0,0,69,4,1,0,0,1,EB]   I need to understand this protocol/message, but I not find information. The Omron W342 does not refer to these messages starts with "0xAB, ..."   Someone can help me? Thank you. Jorge
