1:Type Designation:
RORZE RD-023MS Pulse module
RD-023MS Code allows you to modify the contents of a Modbus 4x range in the slave. This writes to a single register only. Any holding register that exists within the controller can have its contents changed by this message. However, because the controller is actively scanning, it also can alter the content of any holding register at any time. The values are provided in binary up to the maximum capacity of the controller. Unused high order bits must be set to zero. When used with slave address zero (Broadcast mode), all slave controllers load the specified register with the contents specified.
RD-023MS provides a series of tests for checking the communication system between a master device and a slave, or for checking various internal error conditions within a slave. The function uses a two-byte sub-function code field in the query to define the type of test to be performed. The slave echoes both the function code and sub-function code in a normal response. Some of the diagnostics commands cause data to be returned from the remote device in the data field of a normal response.
