George Thomas Reflects on Contemporary Controls' 50 Years "in Control"
To commemorate Contemporary Controls' 50-year anniversary, President and founder George Thomas was interviewed by a long-time friend and industry veteran, Ken Sinclair. In the interview, George and Ken reminisce about the evolution of the industrial and building automation industries and solutions built upon technologies such as ARCNET, Ethernet, Modbus, BACnet, and Sedona.
White Paper: Simplify Machine Integration with Customer's Existing IP & Ethernet Network Infrastructure
Modern machines are comprised of various complex subsystems that communicate via the Internet Protocol (IP) – the backbone of the Internet. The machine builder pre-defines each subsystem IP address and the range of addresses devoted to each machine. This addressing convention may conflict with the addressing policies of the customer potentially jeopardizing a speedy integration of the machine or machines to the plant. This whitepaper examines how an IP router can quickly and effectively integrate these machines to the customer's existing IP infrastructure benefiting both customer and machine builder alike. Additionally, industrial-grade managed, unmanaged, and diagnostic Ethernet switches provide a robust and reliable infrastructure that is beyond par than commercial grade equipment.
