Hint: to transfer larger amounts of data, you could use an Array. 0000118345 00000 n We will be making two MSG instructions, so we will have to create it with two or more elements. The ControlLogix requires no other configuration. Normally, our logic would populate this data file with information that is being sent to the ControlLogix. This will be file #9 (Integer), and well name this file MGCTRL. Im also going to place a random value into the outbox tag (in Monitor Tags mode), and download the project to the target processor. To verify that communication is working, we can add values in the Micro820 controller tags and see if the ControlLogix tags are populated with the data. We will just name this file TOCLX. The easiest way to do that if you have relatively small or simple program is to just use the .EN bit of the MSG itself. ControlLogix messaging is used to send or receive information to another processor. At the bottom of the help file there is a link to the error codes. To enter the processor from the backplane (Step B), specify 0 for the processor slot #. This will bring up the configuration screen. Introduction to FANUC Dual Check Safety (DCS). Learn more in our Media Guide here, or contact us using this form. Heres a simple example of why youd want to communicate data from one PLC to another. For the purpose of this tutorial, we specify that the instruction will be used as an SLC Typed Read, will read from the tag B12:0 and store the data into a controller based tag MSG_ML1100_B12_READ. The Micro820 will only have the array tags that will need to be created for reading from and writing data to.
