You can use remote connection for check V130 PLC in Info mode. Hardware configuration present in info mode.

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
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

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...

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.

Here I would have a problem since the transmission chain is commanded by a variator of frequency
I think you have little choice. Unfortunately, the equipment you have is not up to the task as stated above by many contributors.
Therefore, you need to add one more delta servo to the circuit and apply the proposed application. Or look for a set of equipment from well-known manufacturers with a ready-made application - and this can cost a lot of money.

In this document
Electronic CAM (E-CAM) Function for used servo drive appear.
Please read about this function and try to install ASDA-Soft software

Please post your input diagram connection

In fact, this task is an example similar to the rotary knife or high speed labeling. I doubt you will be able to achieve the accuracy you want with used hardware and software. In such systems, not only speed PID is needed, but also position PID.
In my opinion, you should consider mechanical synchronization between the large print shaft and the chain conveyor in your system. Accordingly, their speeds were the same, and the stop bar on the chain exactly periodically coincided with the start of printing on the cylinder.
By the way, what type of servo driver is used for the large shaft?
p.s. Please read some info in pdfs...

Please post V350 model #. Is it plc new or used?
Please read manual and check jampers inside PLC.

The best way is to use the high-speed counter built into the PLC (I0 or I2) and assign it a to large integer number (ML or DW) in Hardware Config - High speed counter to accumulate an energy value with 0.1 kW increments. Further, this number can simply be displayed on the screen by moving the comma one unit to the left in the display.
Then no floating point calculations are needed.

V130-T38 Connected to IO-A14-A02 How to check if Faulty or Not
in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Posted
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.
