Hullo neighbors, We've got a LOGO! 0BA8 configured to use I8 as an analog input, and the goal is to read the current operating speed of an ABB ACS310 VFD. (we want our PLC to be able to react to any changes in speed from the VFD) Problem is, nobody can figure out how to hook up the analog output from the VFD to the analog input on the PLC. Have tried going from AO -> I8 and have also tried adding a connection from the LOGO! input neutral back to the GND... nothing works. Attached is the terminal diagram for both devices with our poor attempts labeled. Any insights?
Hi dear friends, i'm working with a Siemens PLC LOGO 8 (OBA8) that connected to a Wientek HMI model MT7081IE via Network. and my Problem: i'm trying to get the PLC LOGO time for displaying and editing on the HMI panel, i know that the Time address in the plc logo8 is VM988 and VM989 and VM990 (Hour:Minute:Second) but in easy boilder when i selected an Numerical object there is only VD and VW variables available to select and there is not VM selection (Please see the attached picture). thats way i select VW pisition with the same position Number (for example VW988) for get the Hour value and it's displays a big binary number that contains Hour and minute value in binary, also i can find that witch characters are for hour value and witch one are for minutes value. Please help me that how can i separates the characters and dispalys them into another numerical objects? or another ways to get time values from the OBA8 and displaying on the HMI. Thanks and Regards Saber
Hi I just buy brand new 6ed1052-1md00-0ba8 (Logo 8) PLC and a USB-PPI logo cable from tradeindia.com, I am a embedded system hobbyist and fond of exploring embedded system things such as microcontrollers, FPGAs/CPLDs etc, but this time I want to try PLC. Now my problem is that I am a pure newbe to PLCs, I have a 12 V 1A DC adaaptor can I use it as PLC power supply? and input for switches? How to program my Ladder logic, function block to my plc using PLC Cable (USB) and Ethernet cable. ? Can I use Logosoft7 or only version 8 ? is my usb-ppi cable is useless, can i program my plc by my usb-ppi cable Please guide me how to get start with my PLC?, is there any step-by-step tutorial? because I googled tutorials, getting started but i am confused. Please reply soon Thanks in advance.
