  • Page 45 Modbus Information 4.0 Command Operation: Command operation on the BMS-350 utilizes the “mailbox” concept. The general sequence is as follows: 1. MASTER reads Command Status register (Modbus 40010). If it reads as 0x55 (IDLE) then proceed. Otherwise wait a short time (a few hundred ms would be reasonable) and poll that register again.

  • Page 47 DISCUSSION: Due to the hardware constraints on the BMS-350, the LED display will flicker slightly during normal operation when the Modbus is in use. If the Modbus master polls the BMS-350 for data at a rapid rate, or transfers many registers during each poll, the flickering becomes worse. If the Modbus is being queried on a continuous basis, the display and keypad may become difficult to operate.
