The SOLO Temperature Controller is a single-loop dual-output process temperature controller that can control both heating and cooling simultaneously. It is available in 1/32, 1/16, 1/8, and 1/4 DIN panel sizes and is UL, CUL, and CE-approved. There are four types of control modes: PID (Auto Tuning (AT) function) – Solo Control Modes P stands … Read more
People often ask “What is a PLC?” and “PLC Meaning”. A programmable logic controller (PLC) is a piece of hardware that isolates inputs from outputs. Programs are written to look at the inputs solve logic and set the outputs to perform work. Today we are going to look at the basic fundamental way we program. … Read more
I have been recently asked how you can move data conditionally on an excel spreadsheet once the information has been obtained from the PLC? Monthly data was being collected from the PLC and put on an excel spreadsheet using Omron CX-Server DDE. They wanted at the beginning of each month to move the data to … Read more
Manufacturers have software to program the programmable logic controller (PLC) or the human-machine interface (HMI). However, there are a few free tools that will help in the development of your PLC programs. We will look at three software tools and show how beneficial they can be to you. Free PLC Software Tools Synergy – Share … Read more
Sending email messages from the PLC sounds like an easy task. However, very few applications do this on the production floor. This is probably due to the networks involved, and authentication can be complicated. In our example, we will use a restricted Gmail SMTP server so that no authentication will be required. We will walk … Read more

Let’s look at takt time and determine how to use it to our advantage. What is Takt Time? (Discover Takt Time) This is a German word taken from beats … Read more
PLC programs are typically written in a particular application on a personal computer, then downloaded to the PLC. This downloaded program is similar to compiled code to keep the program efficient. The program is stored in the PLC in battery-backed-up RAM or non-volatile flash memory. Five Different PLC Programming Languages Albert Einstein said, “The world … Read more
Simple mail transfer protocol (SMTP) is the email protocol for sending information. We can use this ability to email from our data logged from the PLC. Faults or errors the PLC detects can be emailed to individuals for correction. Shift reports on productivity can be automatically emailed to recipients. Note: Google is removing “Less Secured … Read more
Process control can be a bit intimidating. We will try and break down both On/Off and PID control in a fun way. This is a simple analogy without any math. On-Off Control Explained On/Off control can be used effectively with temperature control. Everyone’s house usually has a temperature controller that uses an On/Off control. The … Read more
Speaking to individual people is thought to be an easy task. Are you being heard and understood? Talking to individuals is a complex thing. Everyone is unique and has something to contribute.
