Abstract
A system for controlling equipment at a wellsite includes a surface PLC, a first subsea PLC, a second subsea PLC, a first CAN module, a second CAN module, and a CAN network. The surface PLC is configured to receive a parameter that is measured by a sensor and to transmit a first signal to the first subsea PLC, the second subsea PLC, or both in response to the parameter. The first subsea PLC or the second subsea PLC, or both are configured to transmit a second signal to the first CAN module, the second CAN module, or both in response to the first signal. The first CAN module, the second CAN module, or both are configured to transmit a third signal to the CAN network in response to the second signal. The CAN network is configured to control the equipment in response to the third signal.
