The reason why an ushort is used for modbus is that registers are organized in 16 Bits. WebEen Modbus netwerk wordt opgebouwd uit 1 master en maximaal 247 slave units elk met een uniek adres. Communicatie binnen het Modbus netwerk kan via RS485 (Modbus-RTU) of op basis van ethernet (Modbus TCP/IP). Afhankelijk van de toegepaste bussnelheid (baudrate) mag de bekabeling ongeveer 1200 meter zijn. Het aantal op de Modbus …
