Enhanced Vision OPLCs support SD cards that enable application data to be stored and remotely accessed. SD Suite enables you to view and manipulate that data, as well as format cards and perform other tasks. Note that SD Cards also enable , complex web-page hosting, and application cloning between OPLCs.
Remote Operator enables you to use a PC to view and work with a remote controller's HMI panel. You can define any number of controllers, then open multiple sessions to view them simultaneously, while docking or cascading windows according to your preferences.
DataXport creates logs of run-time or stored data from Data Tables and operand regions within Unitronics PLCs. DataXport saves the data logs in .ulp format. You can open these data logs using DataXport's companion application, DataXls, and then export the data to Excel files.
This tool downloads compressed control applications to local or remote Unitronics controllers. You generate a compressed application from within either U90 Ladder or VisiLogic. Your end user will be able to download the application, but will not be able to view or modify it. The tool can download applications and OS.
Here is how you place a user-configurable timer on the HMI screen (click on the element circled in red). Notice the settings I used in the example, particularly Type = Preset, and Keypad Entry box checked.
Unless you're using a V700, the most devices you can communicate with by MODBUS TCP is 4 (without socket sharing, which I won't get into here). Yes, if your data exchange ladder rungs are set up properly you can communicate with up to 4 devices simultaneously.
I'm just showing 2 of the 4 here. Just make sure your timer is long enough to make it through all 4 devices you're communicating with. If you're both reading AND writing to non-Unitronics devices, I would do it a bit differently. Instead of the timer Setting the comm requests, I would have the timer toggle another bit and use a positive transition of the bit to initiate all the reads and a negative transition to initiate all the writes.
If you're communicating with other Unitronics PLCs, there is a handy Read/Write Mixed Data FB that will do both the reads and writes in one operation.
