1：Type Designation:

RKC B871-RCU AC module

RKC B871-RCU allows you to obtain the ON/OFF status of logic coils (Modbus 0x range) used to control discrete outputs from the addressed slave only. Broadcast mode is not supported with this function code. In addition to the slave address and function fields, the message requires that the information field contain the initial coil address to be read (Starting Address) and the number of locations that are interrogated to obtain status data. The addressing allows up to 2000 coils to be obtained at each request; however, the specific slave device may have restrictions that lower the maximum quantity. The coils are numbered from zero; (coil number 1 = zero, coil number 2 = one, coil number 3 = two, and so on). The following table is a sample read output status request to read coils 0020 to 0056 (37 coils) from slave device number 11. Note: This is the structure of the message being sent out to the Modbus network. The byte values below are in hexadecimal display
