  1. Hello guys, I'm in the need to use floating values and do some arithmetic operations with it, as well as comparisons, do you know which function allows me to do that in ST? Or what is the way to do it? If you have an example that would be great, Thanks a lot for your help guys,

    Thank you guys for your support, yes hardware and system parameters were the same, the problem was that I was in the wrong simulation mode that's why I couldn't see any change when I forced to ON the Memory (M3) to start writing to multiple registers command , (I know silly mistake haha) but now its working.  Thanks again guys!

    Hello guys, I'm using a FX3U PLC and I have FX3U-485ADP to communicate using Modbus RTU, I set up the communication in GX Developer using ladder diagram and it's working. So now I put the same code in GX works2 using Structured Ladder and its not working I don't know if in GX works I can use the devices name or I have to use label? It seems that auxiliary relay M8411 is not being activated  , anyone knows if I have to do a different set up for the communication using GX Works? Below you will find the two codes, Thanks a lot for your help,

    Hello guys, I'm new with modbus communication protocol, I try to communicate between PLC and Oriental Motor Controller, but I cannot establish the communication, the RD and SD are turned off. Im using 1 pair wiring, and I connect the TR+(From Oriental controller) to SDA-RDA and TR-(From Oriental controller) to SDB-RDB which is indicated in the manual. I don't know if this is correct because I was reading in the forum and I saw that some of you recommended to invert the  wires? Im trying to setup the PLC as a master and try to write in a register in the slave (Oriental motor controller), but as I mentioned to you I have no communication at all, I think maybe I have something wrong in the code (See attached picture of the code),  Please If some one here can help me to solve this issue, I will be very grateful. Thank you guys
