ABB CI840 3BSE022457R1 Input electronic module

Registers 4200 to 4299 are utilized for the transfer of event messages from the master driver to the SLC. These data are passed to the module when a value of 9903 is placed in register 4200. The ladder logic should copy the information contained in the block of data and then set register 4200 to 0 to inform the module that the messages have been accepted. Registers 4100 to 4199 are used to control the module with ladder logic. For example, if the processor places a value of 9998 in register 4100, the module will perform a warm-boot operation. If the processor places a value of 9999 in this register, the module will perform a cold-boot operation. In this application module, both of these operations perform the same function. They exit the program and then restart the program. Many of the program parameters set in the user configuration must be set at program initialization and cannot be set while the program is running. Therefore, both functions operate the same. The command functions supported by the module and there data formats are discussed in the following section.

Special Function Blocks

 Block identification codes greater than 9900 are utilized to perform special functions in the module. Each Special Function block recognized and used by the module is defined in the following topics. User Constructed Command Block (9901) Block identification code 9901 issues one or more user constructed commands. When the module receives a block 9901 identification code, it places the included commands into the command queue.Session index defined in the module to associate with the command.

Refer to the command list 

section of this documentation for a detailed definition of the fields contained in this block. They are the same as those used in constructed the commands in the command list. There is no response block built by the module to send back to the processor after the block is processed. The module will set register 4100 to a value of zero after the commands have been processed. The commands are placed in the command queue and issued at a high priority.For step control, if the database value is set to -1, the regulating step command of next lower will be executed. If the value in the database is 1, the regulating step command of next higher will be executed. Using block 9901 control of end device may be more reliable.
