This resolution explains how to access the REAC_OUT parameter for the 'BMXDDM16022' module located on an ERIO rack.

Product Line

Environment
Unity

Resolution
The following steps can be used to access and set the REAC_OUT parameter for the 'BMXDDM16022' module located on an ERIO rack. (In this example, the 'BMXDDM16022' module is located in slot 1 of the ERIO rack. We will be setting the REAC_OUT' bit for channel 16)

Create a DDT variable with the type ' T_M_DIS_STD_CH_OUT_CMD'. (This variable will be used to access the REAC_OUT parameter for the BMXDDM16022 module located on the ERIO rack.)
Create a variable of the type 'BOOL' . (This will be used to enable the 'WRITE_CMD_MX' block
Create a variable of the type 'WORD'. (This is used to monitor the status of the 'WRITE"CMD MX' block.
Create a variable of the type 'INT'. (This is used to define the length of the command for the 'WRITE_CMD_MX' block to send)

Expanding the DDT variable will show the 'REAC_OUT' bit.

Add the following FBD logic to the Unity application:
Change the input to the 'ADDM' block to match your application

Note for the ADDM block:

0.0.3 refers to the CPU rack, slot and channel. (This should not be changed)
In this example, 192.168.11.2 is the IP address of the 'BMXCRA31210' module

Assign the variables that were created earlier, to the 'WRITE CMD MX' block.
Assign the 'CHANNEL' parameters. (This is the location of the 'BMXDDM16022' module on the ERIO rack and the channel to set the REAC_OUT parameter. In this example, we use rack 0, slot 1, channel 16)

Build the changes.
Transfer the application to the PLC.
Open the FBD section for the WRITE_CMD_MX' block.
Right click on the WRITE_CMD_MX' block.
Select 'Initialize a new animation table'.

Expand the CMD variable
Set the 'CMD_LEN' value to 1 word. (This should always be set to 1)
Set the REAC_OUT' variable to a value of 1.
Set the enable variable for the 'WRITE_CMD_MX' block to a value of 1 to send the REAC_OUT command.(i.e., 'Enable_WRITE_MX')
