[TD preset on HMI]

I'm having another Timer problem to program a coil that we be energized  for a specific period of time

Use a TE Timer and activate it with a positive transition.

[TD preset on HMI]

Did you look at the Help file? The example is for an older PLC, but the basics are the same. When you place the Timer HMI element on the screen, link to the timer operand you want, check the Preset box, and the Keypad Entry box. Also, set up the Format and other niceties for your HMI element. That's all there is.

[V570 to EX-A1?]

Not 100% certain, but I believe you can. You must use the correct connection cable though.

By the way, the direct replacement for the EX-A1 is the EX-A2X, not the EX-RC1. The EX-RC1 connects to the PLC using CanBus and is a REMOTE expansion adapter. The EX-A2X is a LOCAL expansion adapter, like the EX-A1.

Is there any way that i can set the time and date from the HMI on the Samba.

Just place the circled item on the HMI:

You will need a separate one for each of Date & Time.

You may want to make an action to jump to another screen and then when  the screen is touched jump back to the last display.   This way no buttons you have on the screen are activated when filming out of sleep mode.

This is good advice.

[Sleep screen]

You would run a timer activated by an inverted contact of the General.Touched bit. Use the Out bit of the timer to trigger an Action to change screen brightness.

Mainly because Paul said he has been converting a program to the 350 for only a month.  So in some ways it is sensible to have the 350 working on the very latest version possible at the time. 

Somehow that got past me. Yep, agree that it was warranted.

No doubt we'll hear from Flex saying "why update" and I generally agree with this, but in your case it probably seemed sensible!

Not seeing the sensible reason here, but that doesn't mitigate the issue with the new software.

Paul, my immediate ask would be did it run itself as admin automatically, and if not did you try it manually? 

What Ausman is asking here is did you install VisiLogic "as Administrator" and did you run VisiLogic "as Administrator"?

Can you explain exactly how to index the data table down a line each time?

You appear to be using Data Table Indexed. There is a function for "Insert Row to DTI" that automatically shifts the rows down below the point of insertion.

[Reset TYPE bit]

Not if you want the action to perform only once per button press. Resetting the bit on release would keep the bit set for many cycles.

You're right of course, but that's what the positive transition contact is for.

In ladder, use RESET  COIL to reset the bit you use in HMI button

Better to use the "Release" function of the HMI button to reset the bit.

I see you numbers the time to #1 and the date to #9.... are those arbitrary numbers?  What do they represent?

If you look at the top comment line of the RTC to ASCII UDFB, it explains what the numbers mean. It's basically selecting which format style you want your Time and Date strings to be in.

[Reset TYPE bit]

Having difficulty understanding what you're trying to do. Can you post your code?

My problem is creating a data table that acts as a log. It is supposed to keep track of  - 1. the time when a button is press, and  - 2. the date.

You're on the right track using the UDFB RTC to ASCII. Just place a line like this in your Main Routine:

Then copy those operands over to your Data Table Struct triggered by a positive transition of your button press. You will also need to index the Data Table down a line each time.

the timer off command doesn't seem to work in my programming, which is supposed to turn off the outputs after 5 seconds. of being activated,

Use a positive transition of your button push to activate a Time TE. Use the output bit of the TE to activate your outputs.

Something like this:

You appear to have the Horn coil in both rungs 1 & 2. THAT WILL NOT WORK. You can only have a direct coil in one ladder rung.

[IO UIS-08TC Fault Connection]

Moved to the correct forum.

[Remote web host]

The UniStream line does allow for more complex web pages to be built more easily, but with either the Vision line or UniStream line you will need to have the PLC visible to the internet in order to view a web page from a remote location. That's not a function of the PLC, but rather a function of your network. It's not the most secure method, but I usually just do port forwarding from the router that has the internet connection to the local PLC.

From Joe's explanation, the 4/20 with a 14 bit would round to 3277, but I'm asking if the value in the linear function should be -1 from that (3276)

Ah, sorry, I misunderstood.

but then shouldn't the lower bound be 3276.8 - 1 = 3275.8

Where are you getting a decimal point from? Everything in the context of this discussion involves integers only. Don't confuse the 4-20mA analog input with thermocouple or RTD inputs that provide temperature directly. Even with those, the input is still an integer with an implied decimal point.

aside from using 16383 vs 16384 for whatever reason

It's 16383. There are 2^14 counts, but it starts at zero, so the highest number is 2^14-1 (all 14 bits on would be 2^14-1, or 16383). This is what goes into your linearization block, though you would likely never notice it in the real world if your linearization was off by 1 part in 16384.

[all operand will clear if i download]

Just reply with "Yes". It is suggesting that you clear all operand values, but isn't forcing it.

All M-operands (MB, MI, ML, DW) are retained.

X-Operands (XB, XI, XL, XDW) are kept in memory. Therefor they are processed faster, but they are not backed-up by battery.

This is correct. Thanks for expanding.

is it possible to do a reboot from Ladder/HMI

This handy feature is available with Vision PLCs, but as far as I know it has not been incorporated in the UniStream line.

[Retaining Memory Integers]

Oops, for some reason I thought I was in the UniLogic forum. With VisiLogic, all operands are retained through power cycle or reset if there is a working battery in place.

[How can I implement a high speed counter for paper rolling project?]

The first expansion I/O module always starts address at 32. This allows room for a potential Snap-In module that starts at address 0. Each (digital I/O) module after will start at the next increment of 16, regardless of how many addresses were taken up by prior modules.
