ABB CI854 3BSE025347R1 Output electronic module

This block and block 9902 should be used when controlling single-point, doublepoint and regulating step data points in remote units. If the persistent output qualifier is used in a command list, the command list can be utilized. For points that are controlled using the short or long pulse or no definition given qualifier, block 9901 should be used to control the output. For example, if the command list controls a short pulse output for a single point using the enable code of 2, any time the point’s value in the database changes the command will be executed. When the point changes to a value of 0, the short pulse off command will be executed. When the point changes to a value of 1, the short pulse on command will be executed. This may not be what is desired for the application. If block 9901 is utilized instead, the ladder logic can execute a short pulse on command using a database point it that is set to 1.

Command Control Block (9902) 

The block 9902 identification code is used by the processor to send a list of commands to be placed in the command queue from the user configured command list. Commands placed in the queue with this method need not have their enable bit set in the command list.These 60 words of data contain the command numbers in the command list to enable. The commands in the list will be placed in the command queue for immediate processing by the module. The first command in the list has an index of 0.This field contains the value of 9902 identifying the enable command to the module. 4101 Command count This field contains the number of commands to enable in the command list. Valid values for this field are 1 to 60.

There is no response to this block by the module.

 The module will place the selected commands into the command queue and set register 4100 to a value of 0. If the command references a unit that is not defined, the command will not be placed in the queue. Normal processing of the command list will continue after the commands specified in this block are processed.For digital output control, the use of block 9901 and 9902 is preferred to the use of the command list. The exact state of the output can be specified in the command list and then the command can be enabled through the use of block 9902. Therefore, the command list can contain an short pulse on command. When the user wishes to execute this command (knowing the state of the command), can enable the command with the block 9902 request.
