Stay tuned for a free bonus lesson on MSG instructions for communicating between ControlLogix controllers via ethernet. Remember that in CIP Paths, " 2 " is the Network port and " 1 " is . From the Initiating L71 processor, look at Step A. Then the number of elements we are reading, so if its a tag array inside the source controller we can choose how many elements of the array we want to read. At this point, we come out the front port with a 2, then go to the IP 172.25.154.51. See PRODUCE_DATA[16] is 999 but CONSUME_DATA[16] is still 0. You have to be careful because the word length might not mach up if you are sending a DINT to the SLC (which is 16 bit). A small Video howto, setup communication between 2 Controllogix (and compactLogix) plcs with Consumed and Produced Tags. Ok, so back to the topic at hand. %%EOF It is thus advised to program all the MSG instructions within the same routine. Keep in mind that any time you download, your processor will stop executing logic. In ladder logic, you will need to set up a timer and two MSG instructions. 0000005551 00000 n For an EtherNet based system, we need to input the address of the MicroLogix PLC and specify that this communication will be sent over CIP. You will notice the Enable (EN) bit, the Done (DN) bit, and the Error (ER) bits to the right. 0000003920 00000 n In that case, it would be modbus devices you want to access right?
