When I was in school PLC’s were just in their infancy. We were taught that the PLC consisted of the central processing unit (CPU), analog and digital inputs and outputs. Everything was programmed with dedicated handheld devices and/or software devices on specialized hardware. We now have modern PLC systems that are capable of so much more. Let’s look at how we can now break up these modern PLC system into the seven essential components.
Inputs and Outputs (I/O)
Networking Continue Reading…
We program the Horner XL4 OCS all-in-one controller by using Cscape. We will now use our Cscape software to establish communication. Last time we customized Cscape with icons to make it easier to find, communicate and control the unit. There are two different ways to communicate to the XL4 OCS controller, Ethernet and Serial. There are several different methods within these two ways that the XL4 will communicate. The Cscape software package will communicate both of these ways. We will look at establishing communication using Ethernet, USB (Serial) and Serial RS232.Another two serial ways to communicate would be RS485/RS422 (Serial) and CAN Bus (Serial). These two methods allow multiple controllers connected to the communication network. This is similar to Ethernet. Continue Reading!
The Horner XL4 OCS all-in-one controller is programmed using Csape. Cscape (Control Station Central Application Programming Environment) We will now setup the Cscape software so we can easily communicate and program our controller. Continue Reading!
The Horner XL4 OCS all-in-one controller is programmed using Csape. Cscape (Control Station Central Application Programming Environment) This single programming software package is designed to be easy to use and maintain. We will now install this programming package onto our computer. Continue Reading!
