Initializing Output Data YES or NO This parameter determines if the output data for the module should be initialized with values from the processor. If the value is set to NO (0), the output data will be initialized to 0. If the value is set to YES (1), the data will be initialized with data from the processor. Use of this option requires associated ladder logic to pass the data from the processor to the module. Block Transfer Size 60, 120 or 240 This read-only parameter specifies the number of words in each block transferred between the module and processor.

Float Flag 

YES or NO This flag specifies how the Slave driver will respond to Function Code 3, 6, and 16 commands (read and write Holding Registers) from a remote Master when it is moving 32-bit floating-point data. If the remote Master expects to receive or will send one complete 32-bit floatingpoint value for each count of one (1), then set this parameter to YES. When set to YES, the Slave driver will return values from two consecutive 16-bit internal memory registers (32 total bits) for each count in the read command, or receive 32-bits per count from the Master for write commands. Example: Count = 10, Slave driver will send 20 16-bit registers for 10 total 32-bit floating-point values. If, however, the remote Master sends a count of two (2) for each 32-bit floatingpoint value it expects to receive or send, or, if you do not plan to use floatingpoint data in your application, then set this parameter to NO, which is the default setting. You will also need to set the Float Start and Float Offset parameters to appropriate values whenever the Float Flag parameter is set to YES.

Float Start 

This parameter defines the first register of floating-point data. All requests with register values greater-than or equal to this value will be considered floating-point data requests. This parameter is only used if the Float Flag is enabled. For example, if a value of 7000 is entered, all requests for registers 7000 and above will be considered as floating-point data.
