5SHY4045L0001 3BHB018162R0001 IGCT module

This parameter defines the maximum register in the virtual Modbus database. You should size the database for your application, leaving room for expansion in the future. Requests for registers outside of the range selected are returned with an error message

This value represents the relative starting position in the module's internal Modbus database where the Error/Status data is stored. The table can be placed anywhere in the module's data space. The content of the Error/Status table is updated at the frequency defined in the following parameter. If a value of -1 is set for the parameter, the data is not placed in the database

This parameter specifies the number of program cycles between each update of the Error/Status block data in the module. If the parameter is set to a value of 0, the data is never updated.

BT Read Start Register

This parameter specifies the starting register in the internal Modbus database to write over the backplane.This parameter specifies the number of registers in the internal Modbus database to write over the backplane. This parameter computes the number of blocks to transfer from the module to the backplane. The number of blocks must be >=2 for proper backplane data transfer.

This parameter specifies the starting register in the internal Modbus database to fill with data read over the backplane.This parameter specifies the number of registers in the internal Modbus database to consider from the read operations over the backplane. This parameter computes the number of blocks to transfer from the backplane to the module. The number of blocks must be >=2 for proper backplane data transfer.

This parameter specifies the number of consecutive backplane transfer failure before communications is disabled. If the parameter is set to a value of 0, communications is not disabled.

Description

This parameter specifies if the port will emulate a Modbus master device (0), a Modbus slave device without pass-through (1), a Modbus slave device with pass-through and data swapping (3), or a Modbus slave device with pass-through (4).This flag specifies if the floating point data access functionality is to be implemented. If the float flag is set to Yes, Modbus functions 3, 6, and 16 will interpret floating point values for registers as specified by the following two parameters.

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 in the Float Flag is enabled. For example, if a value of 7000 is entered, all requests for registers 7000 and above are considered as floating point data.
