ABB 3BHE031065R0020 Pulse accumulator module

Refer to the DF1 Command Set for ProSoft Technology Communication Modules documentation for a complete discussion of the structure and content of each command. Care must be taken in constructing each command in the list for predictable operation of the module. If two commands write to the same internal database address of the module, the results will not be as desired. All commands containing invalid data are ignored by the module.Peer-to-peer communication is accomplished by the master constantly polling all the slaves on the network and relaying the messages received. The slaves must contain ladder logic with MSG commands to generate and accept messages. This routing can be used in conjunction with the normal command processing discussed above. If the slave node to be polled is not included in the command list, a special command is required in the command list. Enter a 999 in the Enable Code and the slave’s node address in the Node Address fields of the command. No other parameters are required for a device poll message. This command will force the master port to issue an enquiry request to the slave device without first issuing a command.

This parameter specifies the starting

 register in the internal database to fill with data read over the backplane to the module (processor write block).This parameter specifies the number registers in the internal database to be considered from the read operations over the backplane. This parameter computes the number of blocks to be transferred from the backplane to the module. The number of blocks must be >= 2 for proper backplane data transfer.This parameter specifies the number of successive transfer errors that must occur before the communication ports are shut down. If the parameter is set to 0, the communication ports will continue to operate under all conditions. If the value is set larger than 0 (1 to 65535), communications will cease if the specified number of failures occur.

Error Status Pointer 

This parameter specifies the register location in the module's database where module status data will be stored. If a value less than 0 is entered, the data will not be stored in the database. If the value specified is in the range of 0 to 4940, the data will be placed in the user data area.This parameter specifies the number of milliseconds to wait between the initial issuance of a command. This parameter can be used to delay all commands sent to slaves to avoid "flooding" commands on the network. This parameter does not affect retries of a command as they will be issued when failure is recognized. Enter a value in the range of 0 to 65535. N32:26 5026 Command Error Pointer This parameter sets the address in the internal Modbus database where the command error data will be placed. If the value is set to -1, the data will not be transferred to the database. Enter a value of 0 to 4999.
