ControlLogix Message to PLC-2

Introduction — ControlLogix Message to PLC-2 Processor In this section, we’ll cover how to send a ControlLogix Message to the PLC-2. The PLC-2 is now old, and obsolete. However, there are still quite a few systems that exist, and we need to get data from them. In this case, we’ll […]

ControlLogix Messaging over DH+

Introduction to ControlLogix Messaging over DH+ ControlLogix Messaging over DH+ allows us to read or write data over a DH+ Network. In this case, we will send a message to a PLC-5. We also use the same procedure to send a message to a SLC 5/04 over DH+. The PLC-5 […]

ControlLogix DF1 Messaging

Introduction to ControlLogix DF1 Messaging In this section, we’ll discuss ControlLogix DF1 Messaging to an SLC-500 processor. Connect the Serial port of an L6x or earlier ControlLogix to the serial port of an SLC-500 processor. We’ll use a NULL MODEM cable in this case. Albeit, there are faster communication protocols […]

SLC-500 Messaging

Introduction to SLC-500 Messaging With SLC-500 Messaging, we will transfer the contents of a data file from one processor to another. There are many reasons this might be necessary. For example, if one section of a conveyor shuts down, we might want to tell the upstream conveyor to shut down […]


SLC to ControlLogix Messaging 2

Introduction to SLC to ControlLogix Messaging SLC to ControlLogix Messaging might be easier than you think. In this example, the SLC 5/05 will take 5 integers from the N10 data file, and send those 10 integers to the Allen Bradley ControlLogix processor. The ControlLogix does not have the same addressing […]
