Note: I:0.01 is normally open in the logic. Place your cursor over the I:0.01 Stop contact. This will override any conditions on that bit and will always be Forced On or Forced Off. AccPLC Monitor Mode is shown.įorcing On, Forcing Off – Omron CP1H Online EditingĪ forced contact is one that is always at that state regardless of what the actual I/O or program states. In the project tree window, the mode is always displayed next to the PLC name. Selecting YES will then change to the new mode. When modes are changed in the PLC, CX-Programmer will ask you if you want to proceed. Notice that the icons on the taskbar will also allow you to change the PLC mode. Ctrl + 3, Monitor Icon or PLC | Operating Mode | Monitor from the main menu. Let’s put our CP1H controller into monitor mode. Present and set values cannot be modified using programming devices. The operating status of the CPU unit can be monitored, but bits cannot be forced and/or set or reset. RUN mode is used for normal system operation. This mode is used for system adjustments.
The present values of word data can be modified. The set values and present values of timers and counters can be modified. The operating status of the CPU unit can be monitored, bits can be forced and/or set or reset. I/O is processed in the same way as in RUN mode. In MONITOR mode the CPU unit is running, so your logic will be executed. Depending on the PLC type there may be other options as well. User programming can be created or modified, memory can be cleared, and programs can be checked. In PROGRAM mode the CPU unit is stopped so your logic will not be executed. Omron PLCs usually have three different modes Program Monitor and Run. If the items are not being monitored (Green highlights on the ladder diagram) then click the monitoring icon, Ctrl + M or go to PLC | Monitor | Monitoring in the main menu. Your screen should look similar to the following: We will start by calling up our Start Stop and Jog circuit program from our previous post.

Here is the URL link for this free literature:Ī copy of this guide is a good tool to use when you learn to program using the CX-Programmer.ĬX-One software has been around for a number of years. The CX-Programmer Introduction Guide provides step by step of the process of using the software. Setting, Forcing and Online Editing – Video Previously in this CP1H series, we have discussed: Online programming (online editing) will also be done with our CP1H controller. Forcing and setting the inputs and outputs will demonstrate to us the operation of the logic. We will use the Start Stop and Jog circuit that we have developed to test the program in the PLC.
This is usually used for troubleshooting and testing of the PLC logic. CX-Programmer can also set or force inputs and outputs in the controller. The next scan will now solve the new or modified logic in the PLC. This is when the PLC is solving logic and at the end of the scan, programming logic is added or modified.

The Omron CP1H series of programmable logic controllers are capable of online programming. We will now look at online editing, setting, and forcing that can be done on the Omron CP1H controller.
