Ecopetrol, the national oil company of Colombia, is using Opto 22 SNAP PACs to maximize output and securely monitor and control its pumping locations throughout the country. The SNAP PACs communicate via Modbus and Profibus as they regulate valve positioning, pumpjack motors, variable frequency drives and other devices to maintain the desired flowrate. Equipment status and other data is communicated over wireless Ethernet to Ecopetrol headquarters in Bogota.
