Practical Tips and Techniques
Up, down, interval, flashing, memory retentive, etc counters are discussed.
We will now look at the Click PLC Modbus TCP remote io. The Click PLC can use remote inputs and outputs from Stride. The Stride Field I/O Modules are simple and compact. They provide an economical means to connect inputs and outputs to an Ethernet Modbus TCP communication network. Every module operates as a standalone … Read more
Counters are used in a lot of PLC programs that I have seen. A timing chart is a secret behind understanding the counter that you need in your application. Making a timing chart before writing the program will ensure that all of the information will be accounted. The secret to using counters is a good … Read more
A majority of programmable logic controller (PLC) programs will include a counter instruction. The Productivity 1000 Series PLC has a couple of different counter instructions for your program. Under the data handling instructions, we have the increment/decrement instruction (INC). We could use this with the compare contact (CMP) instruction that we discussed in our Contact … Read more
A majority of the programmable logic controller (PLC) programs will include a counter instruction. The BRX Do-More series of programmable logic controllers have several different counters available for your program. There are five different basic counter instructions in the PLC. The memory area for counters (CT) includes the Counter PVs (Present Values) Counter SVs (Set … Read more
The Omron CP1H series of programmable logic controllers are capable of having 4096 basic counters. There are two basic counter instructions in the PLC. Each of the basic instructions can be either binary or BCD. The memory area for counters has separate areas for the Counter PVs (Present values) and the Counter Completion Flags. We … Read more
Timers and counters are used in the majority of PLC programs. We will not look at how timers and counters can be programmed in the Horner XL4 OCS all-in-one controller.
