  1. I2C Communication

    The communication is strictly serial.  The chip that I would be communicating with is embedded inside a finished product.  The communication is used to calibrate the device prior to shipment.  The customer is currently using a PC-based control and a National Instruments USB-to-I2C converter.  It works, but it's a band-aid system.  They want to upgrade to something that can better handle the industrial environment and is easier to troubleshoot.  If necessary, I can use the PLC for setting the calibration conditions, then a mini-PC to handle the communcation between the PLC and the finished product.  I'd rather not as it adds another layer to the system, but I can if that's my best bet.
  2. I2C Communication

    Has anyone heard of a way to communicate with an I2C device over Ethernet/IP from a CompactLogix PLC?  There are plenty of ways to do it from a PC over a USB-to-I2C converter, but doing it from a PLC seems to be a rare event. I appreciate the help.
