Introduction to the SLC-500 Selectable Timed Interrupt The SLC-500 Selectable Timed Interrupt allows you to guarantee the execution of a routine in a given amount of time. For example, we might have a PID instruction that we need to execute every 50ms. We cannot guarantee the execution time of standard Read More »
Introduction to Delaying an Output On and Off Today, we’ll discuss delaying an output on and off. In this case, I have a heater in the office, and a blower (fan). When the heater energizes, the blower (fan) will start after 2 minutes. This allows the heater time to warm Read More »
Introduction to PLC-5 to ControlLogix Conversion RSLogix / Studio 5000 has a built in utility for PLC-5 to ControlLogix Conversion. Likewise, we can use the same procedure for converting an SLC-500 project. Because the PLC-5 is now obsolete, we will convert a PLC-5 project to use in a ControlLogix system. Read More »
Introduction to RSLinx Gateway RSLinx Gateway is a version of RSLinx which allows you to access other types of networks. For exmple, you will have one computer that has a 1784-KTx or 1784-PKTx. This computer is connected to a Data Highway Plus network. This computer is also on the Ethernet Read More »
Introduction to Communicating with Micrologix 1000 While there are many methods for Communicating with Micrologix 1000, Here we will discuss the most common method. In this case, we will directly connect to the front port using DF1 (RS232) protocol. Other methods include communicating via NET-AIC, or going through a ControlLogix Read More »
Introduction to RSNetworx for DeviceNet We use RSNetworx for DeviceNet to map field devices into a memory location in the processor. Each device on the network has a node number and an image size (amount of data). Therefore, we must configure where this data will appear in the Controller Tag Read More »
Introduction to Studio 5000 (RSLogix) Training When looking for Studio 5000 (RSLogix) Training options, it’s important to find a company that will customize the course. You need a company who will adjust the course according to your training needs. At the same time, the instructor should have knowledge of the Read More »
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 Read More »
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 Read More »
Introduction to RS232 to DH+ Passthru on the SLC 5/04 With RS232 to DH+ Passthru, we will connect through the serial port on a processor, and access the DH+ network. With this in mind, another option would be the 1784-U2DHP. However this device might cost around $2,000 to purchase. In Read More »
