Mud Pump Console
The Mud Pump Console forms the interface between the operator and Mud Pump control/status I/O of the PLC system. The Mud Pump Console I/O is connected to one remote rack, located in the console and connected by dual Ethernet Fiber Optic cable to MOXA, also located in the console, which convert the signals for use by the fiber optic cable running to the PLC. Below is an overview of the signals exchanged between this console and the PLC system.
