Use this parameter to identify the module and the configuration file. Read Register Start 0 to 9999 Specifies the start of the Read Data area in module memory. Data in this area is transferred from the module to the processor. Read Register Count 0 to 10,000 Specifies the size of the Read Data area. Write Register Start 0 to 9999 Specifies the start of the Write Data area in module memory. Data in this area is transferred from the processor to the module. Write Register Count 0 to 10,000 Specifies the size of the Write Data area. Backplane Fail Count 0 to 65535 Specifies the number of consecutive backplane transfer failures that can occur before communications are halted. Error/Status Block Pointer -1 to 9939 Starting register location in the module’s database for the error/status table. If a value of -1 is entered, the error/status data is not placed in the database. This data must be placed in the read data range of module memory. This data includes the module version information and all server error/status data. Refer to MBS.STATUS (page 64) for more information. Initialize Input Image Yes or No This parameter determines if the input image data and the module’s Read Register Data values are initialized with Read Register Data values from the processor. If you set the parameter to No, the Read Register Data values in the module are set to 0 upon initialization. If you set the parameter to Yes, the data is initialized with Read Register Data values from the processor. This option requires associated ladder logic to pass the data from the processor to the module. Block Transfer Size 60, 120 or 240 Specifies the number of words in each block transferred between the module and processor. Slot Number 1 to x Specifies the slot in the CompactLogix or MicroLogix 1500- LRP rack for the module.

If you set the parameter to YES, the CTS line is monitored and must be high before the module sends data. Normally, this parameter is required when half-duplex modems are used for communication (2-wire). This procedure is commonly referred to as hardware handshaking. Float Flag Yes or No Specifies how the Slave driver responds 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. Note: Most applications using floating-point data do not need this parameter enabled.

Page 41 of 159 If the remote Master expects to receive or sends one complete 32-bit floating-point value for each count of one (1), then set this parameter to YES. When set to YES, the Slave driver returns 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 sends 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 floating-point value it expects to receive or send, or, if you do not plan to use floating-point data in your application, then set this parameter to NO, which is the default setting. You 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 0 to 9998 Defines the first register of floating-point data. All requests with register values greater-than or equal to this value is considered floating-point data requests. This parameter is only used if the Float Flag is enabled. For example, if you enter a value of 7000, all requests for registers 7000 and above are considered as floating-point data. Float Offset 0 to 9998 Defines the start register for floating-point data in the internal database. This parameter is used only if the Float Flag is enabled. For example, if you set the Float Offset value to 3000 and the float start parameter to 7000, data requests for register 7000 use the internal Modbus register 3000
