Hi all, Working in GXWorks2 with an FX2 CPU. When i powercycle the PLC, the plc stays in STOP. With the software i can put him into RUN, also found an setting to give RUN signal by an digital input. How can i configure the PLC to always go into RUN after power up / power cycle?
Trying to figure out a fix to a processor issue, I have 2 1785-L40E processors a series E and F. Both when inserted into the rack and powered up go straight to a solid red BATT and PROC light as well as a Solid amber Force light, they both wont even attempt to start a boot up sequence. When connected through DH+ and ENET there is no visibility to either of these processors. These are refurbished processors.
After getting my logic to work. I went in and implemented the logic with my plc. It worked but in order for me to test part 2 of it, I have to turn the machine off and turn it back on as part of a reset feature. When I turn the machine back on, it wipes out my logic and goes back to its default logic. It's almost like I never changed anything. I connected my pc to the plc and connected to plc, pulled up the code and ran it on "Online Mode" where i can make changes and send them to the plc and yet again it wipes out whatever changes I had made and goes back to its default. Any suggestions?
Hi everyone, I need some help with my PLC programming. I am currently using a twincat 2 software and a Beckhoff CX 8090. Basically, the gist of my program is to send and receive data and datalog the input data received from the sensors and timestamp the received data for every 1 second. I want to create a boot up counter where it will count the number of times my data logging program has restarted(if it did). This boot up counter serves as a health monitoring check to ensure that my program is running perfectly and thus, not restarting randomly when it shouldn't. I am more familiar with structured text so if you have a solution, kindly post it in structured text form. Your help would be greatly appreciated. Best regards, DeadPool
