  1. Motor Control Sequencing

    I'm new to Siemens software with little PLC programming experience, but the only mechanic with any experience at all.  So here it goes.  Our plant has equipment using S7 1200 PLC (TIA Portal V13 and Startdrive) and three G120C PN drives controlling conveyors.  Currently the drives are controlled through an HMI to control the speed.  We need to be able to slow the speed of these conveyors automatically after an external counter reaches a predetermined set point so an elevator can empty the product and return to the up position then return the speed control back over to the HMI set points.      We are using a Red Lion counter with a preset count for counting boxes.  When the preset count is reached it will send an output signal to the S7 1200 PLC to slow down the roller conveyors and the counter will reset to ZERO automatically to count the next batch.  After the elevator empties the load and returns to the up position and makes contact with the UP limit switch we need the Conveyors to return to the normal running speed. Any help would be appreciated.
  2. Looks like we may be keeping devicenet, just going with something modern. Thanks for your help  
  3. We cruuently have a AB 5/04 with Devicenet scanner.  We would like to replace the devicenet with a 1747 SN scanner and Flex IO using 1794 A5B2 RIO
  4. Newbee here,  The plant I work at has an old piece of equipment currently using Cutler Hammer DN50 devicenet modules which are getting hard to find parts for.  Each DN50 remote IO rack has 4 modules with the first module and the power supply in one.  Management wants to convert it to AB Flex IO.  My questions are, What will be required to get this done?  Will it involve any reprogramming? Thanks for your help in advance.
