In such conditions, the frequency of the signals arriving at the discrete inputs from the absolute encoder is approximately 5000Hz (1/1.2Hz=0.8s 4096/0.8s=5120Hz). The operating frequency of discrete inputs is 100Hz (10ms Response time). Therefore, they will not have time to see rapid code changes in standard mode. It will not be possible to use high-speed inputs because there are only 3 of them in this PLC. The only way out is to try to quickly read standard inputs using interrupts in the PLC. Read about it in the help and experiment with the absolute encoder if you have one available.

I think you need to test your RS232 port. Please found terminal program and set COM port. Try to connect TX and RX pin in RS232 DB9 connector (pin2 connect to pin3). Type any symbol in TX and send it to port - you must see the same symbol in RX menu. If you do not see sended symbol in RX display - your hardware-software configuration is not correct or Ethernet to RS232 adapter is damaged. P.S. Is it this adapter correctly powered?

Marking rungs with color even caused a scroll bug that was already fixed in version 94. It is interesting that now there is no file with version changes on the Unitronics site. This is probably to introduce information about the following new 96 version features.

Yes. Only set Analog Input MI... in Hardware Config and place number on screen with the same MI.

Check list Power supply connection (for IO) >>>>Comm Cable >>> EX-A2X>>>>IO-A14-A02 >>>PLC Sometimes power supply for IO is separate and sw on after PLC power supply. Than no IO Expansion in PLC. Please try to reset PLC via Info mode and check IO.

You can use remote connection for check V130 PLC in Info mode. Hardware configuration present in info mode. https://www.unitronicsplc.com/Download/SoftwareHelp/VisiLogic_Knowledgebase/Utilities/Information_Mode.htm

In Communication and OS you can check OS version. If it is not updated, Visilogic go to OS update mode and load needed SW to PLC. If this process does not start or fails, please send message to support@unitronics.com

In standard multi-pump control used one PID loop for one pump. All other pumps works in start-stop mode. Some info about multi-pump configuration ATV610_Multi-pump_en.pdf Schneider-VW3A3502-Manual.pdf you can see standard multi-pump application setup.

Actually, this topic is about what to do with the PLC if it does not respond. This action is called Factory Boot mode. Try to get there by tapping on the screen before turning on and several times after turning on. This is described in detail in the topic.

Please see this topic If all recovery steps filed - your PLC has damaged hardware. I think the PLC has a problem with corrosion inside. This is suggested by the appearance of the front panel of the device where the PLC is installed - perhaps something wet leaked from above.

I try to find some info about STO, SS1, SS2 safety function in standard servodrive. Maybe it is useful AN00206-Implementing_safety_functions_on_ABB_servo_drives_Rev_G_EN.pdf And some info for forum users about STO, SS1, SS2 safety function TB-Understanding Servo Safety Funcionality and SIL ratings.pdf

Unfortunately, you did not say anything about the application itself, for which the servo motor is used. There are probably safety requirements and standards for this application. Usually, the standards are based on the current state of technology development. Special safety inputs for converters have appeared quite recently and have accordingly been added to existing standards as additions. On the one hand, you want to stop the engine quickly, and on the other hand, you say that the fastest way to do this is to turn off the power. So I think only following the safety standard is correct. If it involves turning off the power supply of the power unit, then it should be done that way. The frequency of turning on and off the power will not be high anyway.

It is in Hz for High Speed Counter As far as I remember, with Shaft encoder, it is 2 or 4 times larger, depending on the selected encoder.

Paying attention to servo motors, we must take into account that they are usually used in positioning mode. This mode involves setting the final coordinate in advance. That is, the activation of the safety system must change the task of the servo drive so that it stops as soon as possible. Disconnecting the motor from the servo drive via safety relay is generally unacceptable. This will probably cause the driver to crash. Disconnecting power from the servo driver will not provide the desired instant stop. Therefore, after studying manual for the Unitronics servo driver, I came to the conclusion that the most effective in your case is the use of discrete input signals P-OT and N-OT. This two signal can be selected via Parameters (p.64-65). This two signal can be used as a command for an unconditional stop. Using the zero clamp settings to work out the P-OT and N-OT mode, you can create safe application. Additionally, you can add Unitronics motor with a brake and create a configuration for guaranteed holding of the motor in the stop position. Safety relay has two ot more contact - that can be used for generate P-OT and N-OT signal simultaneously. For additional information please contat support@unitronics.com. P.S. I must draw your attention to the need for careful study of legal norms - national standards that regulate the operation of the safety system for the equipment where the operation of the servo drive is planned. I have studied these documents for many types of equipment, so all your steps and schematics should follow these requirements.

If you use MB0 with SET condition - your configuration is restartet at every scan. Please use Direct SB2 for Ethernet configuration startup.

If other parts of the code of similar content without the network variable work, then I think that it is just that variable that is pulsating. It is updated very quickly and the condition that should be fulfilled simply "does not see" it. I suggest you "remember" this variable via SET Coil (Part There is Direct Coil now) and see if it works.

Is it CPU-for-Panel plugged into the back of a UniStream® HMI panel?

Please post used Unisream hardware. Software Version needed also.

It is possible Tag is used for Button on screen - it can not be active in ladder. Please use Find option for this Tag

Please post your PLC model # V700 and other Vision plc (V350...V1210) has different Ethernet setup.

While browsing the Internet, I came across one of the forums on the topic of play sets for children and teenagers of different years of production. This 1950 set is definitely unique... link with some info

To deactivate the variable - the Disable view option bit present in the properties, for the button - the Disable mode option bit present in the properties. You can set this bit by pressing a button and starting a timer to reset this bit. You can also use the Hide option bit for the button - touch is not possible if there is no button on the screen.
