ABB 07KT98 GJR5253100R427807KT98 H3 module

Command Control Bits Block (6000) Use block 6000 to list up to 16 Modbus Commands in the configuration file MNET.CFG, then dynamically set the specific commands to execute per Client. The Modbus command execution will be continuous and sequential by the Client order and within each Client by the Command sequence order as listed in the configuration file. To dynamically modify the Client number and/or the Modbus Commands to execute from the list, modify the bit structure in the Client assigned registers and then re-activate the Block 6000.

Command Control Bits Request description (Write Block) 

The Command Control Bits block places commands from the command list into the command queue. The Client has a command queue of up to 16 commands. The module services commands in the queue before the user defined command list. This gives high priority to commands in the queue. Commands placed in the queue through this mechanism must be defined in the Modbus Command List section of the configuration file. Note: The Enable parameter in the Modbus Command List section of the configuration file must be set to either 0 or 1 and no other value, otherwise the configuration file will not be properly read when the file is transferred to the module. The value can be either 0 or 1 because the execution of the command is controlled by Blocks 5001 to 5016 and by Block 6000.

Block Request from Processor to Module

Words 5001 to 5030 each contain set bits that correspond to the Command sequence position for each client in the configuration file. For example, when Client 17 has in its configuration list all 16 Modbus commands and it is desired to execute only commands indexed 1, 8, 10 and 13, then word offset 5018 will have the following bits set:(MSB 0010 0101 0000 0010 LSB). Command Control Bits Response description (Read Block) The module responds to a command control block with a block containing the number of commands added to the command queue for the port. The following table describes the format for this block.
