All MDSA winches are designed to be connected to the Customer’s telemetry system and to Debit-E Express Telemetry system via a free RS-485 port over MODBUS RTU.
Express Telemetry system by CTD:
Allows for monitoring the winch operation in near real-time mode:
– Allows for viewing summary information about all connected winches (status, depth, power, speed, communication quality etc.) on 1 page:
Winch operation graph
Allows for obtaining winch operation graphs for an arbitrary time interval;
– Allows for sending text messages about the winch operation process to specified telephone numbers:
Allows for remote SA Unit control: lifting and locking in the lubricator before the service team arrives, unscheduled startup of a cleaning cycle, lifting from error state, etc.
– Allows for monitoring and control from any device connected to the Internet (computers, tablets, or smartphones) without installing additional software:
Summary for the entire stock
Allows for remote changing of setpoints.
Allows for differentiating access rights in the Personal Account:
– Allows for connecting non-standard functions (operator presence control, text message about cabinet opening, sensor polling, and other telemetry data transmission, etc.).
