Is it an explanation in Help: Of course, Output result is changed in accordance to operation and inputs conditions. Do it in Ladder to see how it works.

It may be, But I am not sure. And I cannot tell nothing about how reliable PLC will be from now. Continue follow-up. As I suggested - sheck SD card, or replace for new one from good known manufacturer.

What exactly would you like to do with Inputs/Outputs? Mask/Unmask? There are operations Test bit/Set bit/Reset bit. If this is not fit your needs - you can write simple subroutine for this.

You should newer touch an internal SD card!!! This will brick your PLC with no warranty!!! In your case it is recommended to extract an external SD card and check the next: - Check how many files are at SD card - many files will make load process of PLC slow, or stuck PLC. You have to use SD management option to keep SD card as free as possible. - Scan SD card for File System errors. If found - copy all files to PC and format SD card. *Recommended to make Full Format.

Thank for update, Milosh! This may help for other to solve similar problems.

This is "debug" option in some version of VisiLogic, which should not be used. In last version this option has deleted. Use last VisiLogic version.

Your project is empty, so you cannot manage outputs. EX-RC1 intended to be in pair with UNICAN master PLC and than manage outputs from Master PLC. If you use EX-RC1 alone, you have to reset following 3 SBs: Than you can locally set/reset Outputs.

1. Unitronics recommend to use USB-2.0 sertified USB cable of good quality, not "junk". USB cable should have twisted pair at Data lines (preferred with schield), and common schield. With good USB cable you will have no problem of communication. 1. To use USB connection, you have to install USB driver before you connect USB cable. Wgen connected USB cable before installing USB driver from PLC communication settings, it may not work properly. So you have to uninstall not-Unitronics driver before installing Unitronics driver. *You have to run U90Ladder as Administrator to properly install USB driver and properlu work with U90Ladder

1. Look at following article: https://support.unitronics.com/index.php?/selfhelp/view-article/calculate-totalizing-or-integral 2. Expansion module you use IO-D16A3-RO16 is relatively "slow", as it ise serial type of communication with PLC. But if you read sequential values at fixed time interval, let's say, 1 sec, it will work for you. 2. Other way is to use "Frequency Measurement" option: This can give you estimated frequensy, proportional to flow, at selected time interval. You can use MI or DW for both, High Speed Counter and for Frequency Measurement.

Or you can modify displays in copy of V430 project to fit V350 display, than you will be able to convert project to V350. Anyway, check if all displays are complete after such changes.

Add PLc Model and picture where do you see this option.

Each of Windows updates add more security and require to correct access rigts, especially to allow write/store to directories you previously stored without problems. It is recommended to consult IT (or find at Internet) how to allow to store project files to specific directory. So there is not a Unitronics software problem.B.R.

Just generate 1 to 5 and then use (n-1).

Is old used version 9.8.09, or 9.8.90?

Let's suppose that PLC model allow Remote connection. To access PLC on internal network, you should use WiFi connection to company network. *You cannot reach company internal IP addresses from Internet until IT will allow port forwarding for such connection. *You may need to temporary disable Cellular Data to reliably connect to PLC.

First, please explain your problem in details.

UniLogic is not designed to open an additional sessions. There is no change.

Sent your request to support@unitronics.com Add U90Ladder version number

Hello, You have to follow recommendation to use VisiLogic version 9.8.80 or below. This function is not available in later versions. As a work-around Customer may realize this function in Ladder. Best regards, Accelerate Alternative.vlp

Use string with power-up value.

1. Enter router configuration. 2a. Set Router WAN interface as main interface (disable cellular) and enable DHCP Client. 2b. Or set WiFi as main interface (disable cellular) and enable DHCP Client. 3a. Connect WAN to network (ADSL, Company LAN, etc.). 3b. Connect Router WiFi to Cellular (telephone) or company Access Point. 4. Run Firmware update. *Probably you may bneed to run it number of times, dependent of network condition. Finish Firmware update. *Firmware is 15-20MB. If nothing of this does not help - send request for firmware to support@unitronics.com. B.R.

Oath, I join to kratmel and thank you too! By the way, Unitronics provide Random Number Generator example for V280 and V570 PLCs in directory: C:\Program Files (x86)\Unitronics\Unitronics VisiLogic_C\Examples\Version 900\Project examples\ladder\ There are many other examples. Unitronics has special page "Tools & Applications from the Unitronics Community", where community members can share his examples/utility: https://www.unitronicsplc.com/support-tools-and-applications/ B.R.

By design , only one UniLogic Studio allowed to start.

These modules require EX-A2X IO Expansion Adapter. *All modules with name starting "IO-" require adapter.
