Omron PLC Center

Welcome back to Om-ron PLC dot com , Last time we mentioned the maintenance of PLC in the Relay output. In the event that lead to the induction load. That require additional protection circuit. From now on, we have learned circuit protection first then there is the use of electronic equipment, electronics, called RC (RC Method) well then come to learn each other to the protection circuit in the lead. relay output to the load to the induction of a second. That is the use of electronic equipment, electronics, called a diode.

2. Diode Method.

Circuit of the use of diode circuits can be found in Figure 1, below.

For this method, we use a diode parallel to the load on the circuit. When the touch of a Three layout of the PLC input will work with current flowing through the contacts of the relay to the load. The direction of current flow in a stream running through to the positive load. (Which is a load inductance) to stop with the negative terminal of supply. The magnetic field points in the load inductance. Make the work load. In the diode-stroke does not affect anything because the timing circuits reason that the diode itself to be bias. But when the Tree Layout output to stop working. (Contact output layout of the Three separate instantaneously) in the stroke itself, this magnetic field that points in the load inductance is caused to emit energy. In the moment of birth itself will emit this energy at a voltage proportional to flow rate changes. Resulting voltage across the contacts of the Tree layout output (transient). (more…)

Get to know maintenance and PLC Troubleshooting. Start with the output of each unit before a prelude In this example, Omron PLC’s that many of you may be familiar with in the past or are still in use today are the same. (Nanjing tolerance of him is on) are the output of generation units CP1L.

1. Unit Contact Output.

Contact Output for the maintenance of essential. When it is time to use one of relay contacts page and then the resistance will be more The more frequently cut. The high volume flows. Lifetime of relay contacts page just so short. Thus, during the re layout output to use it regardless of load current to be output to relay to the cut with Be very careful and to consider the application output to the relay unit is used in the circuit. In the event that leads to the load inductor (coil), which in this case. Moment of contacts separated abruptly Magnetic field in the coil is reduced. This will cause a voltage proportional to flow rate changes. Own rhythm and this is the voltage across the contacts page. Which was high enough to destroy the contacts page at a glance. Pressure that occurs when the contacts page, we first separate the pressure “Transient” as the voltage during a short period at the beginning. Because of this pressure may be high enough to damage the contacts page. Therefore, if a load inductor (coil) to the more external protection circuit. With many different types depending on the voltage used in editing Horizontal resolution which can be viewed from the circuit as shown. (more…)

“Change” PLC old version of the “new” to reduce costs. Decrease in production. How to optimize each.

Change the PLC to your old, better … to help save money on the maintenance of the lower Decrease in production. Because the stability in the new work. Reduce waste at work. Add high performance version is a lot to choose from. A new function. Easy to use, easy to choose …

Old generation
C20, C @ @ P, C @ @ K, C @ @ H, CPM1/CPM1A, CPM2A.

The new version is CP1E.

Feature:
-Supported I / O up 160 points.
-Sequence for a simple program.
-Supports High-speed pulse Input / Output. (more…)
