    • Industry standard 52mm panel cutout allows the use of exising panel/tool designs thereby lowering development cost. • Battery State-of-Charge (BSOC) can be calculated in the 3140 or sent to the 3140 by the Model F2A (or equivalent CANopen-based motor controller).

  • Page 5: 3: Canopen Communications

    NODE ADDRESSES The node address of the Model 3140 can be 1 to 127 and is used by CANopen to route messages to the Model 3140 and to denote messages from the Model 3140. The node address is part of the COB-ID and therefore also plays a part in message priority and bus arbitration.
  • Page 6 NMT (Network Management Transmission) messages are the highest priority message available. The NMT message puts the Model 3140 into one of the four defined states. These messages have 1 byte of data sent by the master; the slave does not respond with any data to an NMT. The Model 3140 state value is transmitted with each heartbeat message.
  • Page 7 The heartbeat message is a very low priority message, periodically sent by each slave device on the bus. The heartbeat message has a single byte of data and requires no response. Once the Model 3140 is in the Pre- Operational state, the next heartbeat will be issued and will continue until communication is stopped.
  • Page 8 Curtis 3140 Manual – Nov. 2017 POWER-UP SEQUENCE Upon power-up or transition from Pre-operational to Operational state, the 3140 will go through a three- second diagnostic sequence. The LCD will be blank for the first second, then turn on all segments for one second, then blank for one second.
