PAROCK1: AB Logix To Modbus (Master / Slave)
 
Now a software solution is available for your Modbus needs in Rockwell Allen-Bradley Logix family processors. It is an Add-on instruction for v16 or later, (other solutions are available for pre v16 systems). For hardware interface use PLC’s channel 0 (for serial) or TCP/IP via EWEB modules to have as many TCP/IP devices or serial devices (via MOXA or similar product), (some limits apply based on system configurations. Com settings depend on hardware used. Contact Parijat Control ware, Inc., (PCI), for details). Connect any Modbus Master or Slave device (s) to your Logix PLC, including flow computers, analyzers, VFDs, Power Monitors, Level gauges, Smart I/O, etc. All the public/native function codes are supported. 32-Bit integers/floats as single entity are supported with byte and word level swapping.
