SLC500 Measure Resistance
By panic mode in PLC Sample Code
This was one of my early projects. I had to measure resistance in pretty
wide range on a delicate circuit (subject was changing value and in range
from few ohms to more than 1MOhm).
Normally I would have used something like RTD transducer but I just couldn't
find anything suitable for that range (every transducer I could find was
stopping at some 8 or 10k i needed at least 100x more).
The time was running out so I had to put something together and fast.
This is it. Initially this circuit was using dedicated regulated
low voltage power supply but since I had spare analog input(s)
I replaced that power supply with voltage divider (Panel had existing
24VDC power supply) and simply had to monitor that voltage because
it was not regulated any more (the 24VDC was regulated but the output
of divider was changing depending on test conditions).
Although we like to avoid custom designs this turned out to be so simple
cheap easy to use and worked extremly well. It is so small that there
was no need for PCB two resistors ware connected directly to terminals.
Accuracy off course could not match the 8-digits of precission benchtop
multimeter but it was on pair with my multimeters which is more
than I could ask for. I didn't test it for significant ambient changes
(temperature and humitity).
There are several ways to do the math for this and in fact used aproach is
not the simplest or most efficient. But it is good example on how simple
DC circuits knowledge and very basic match can be used in practice.
R1 and R2 are not critical and don't need to be accurate either (just need to
produce voltage that fits selected range for used input card.
It is robust enough. In fact I was surprised to see results when R1/R2 ratio
was adjusted to produce only 1 Volt (what kind of ADC they have in their cards?).

simple backup utility
By panic mode in Free Utilities
simple command line backup utility. monitors one folder and when files of given type are detected, they are copied to another location (or two). original can be deleted or renamed. to avoid typing, all options are stored in an INI file. if missing, this file is created once the program is started... successful actions are highlighted in green, failed ones are red. this should also work on older Windows such as Win2K (tested) and WinXP (not tested).
use at own risk, this was literally something i just winged... if there is a bug or feature required, let me know. i will try to get to it as time allows.

Pick and Place
By panic mode in PLC Sample Code
I just tried to contribute a little for our Mitsubishi section.
This ladder code was written for FX PLC but it will work with
little or no changes on any PLC. For those who don't have
software I provided pdf version of the printout (it doesn't
look nearly as good as on screen version but I don't have or don't know
way to change that - i don't remember need to print plc program in
such a long time...). Maybe someone will like screenshot version...
Sequencer is counter based. This imaginary machine uses only three
pneumatic actuators (gripper lift and transfer) with reed switches
there is pair of photoeyes and it even controls two conveyors.
Load conveyor runs until part reaches photoeye then it waits for
pick and place to pick part. Unload side conveyor moves just
enough to make room for next part and then stops.
Program sections include alarms sequencer etc and has
auto manual and step mode. Step mode is same as auto but
intended for step by step execution which can be very handy for
troubleshooting. I hope someone will like it because it took me
nearly two hours to make darn thing and about half an hour
to make those pdfs.

NT31 data entry
By panic mode in HMI Sample Code
Attached file is sample basic HMI application for Omron NT series HMIs.
It shows how to do numeric and string input and it contains compact
version of ASCII keyboard which will fit NT31 (will work on any other NT screen)
which is something my version of NTST does not include and keypads for 620
screens don't fit (NTST menu Windows Symbol Manager).
Note when creating keypads they have to be in "1-3999 (Window/Keyboard)"
while normal screens are in folder "1-3999 (Standard)"
When creating new keypad from scratch:
create new keyboard screen note dashed line rectangle. that indicates size
of the popup window. all new keys/buttons must fit inside (what doesn't fit
into frame will not be downloaded to HMI and will not show up)
when creating standard screen:
drop numerical input or string input object onto screen. note that there are
two overlapped objects that are linked. one of them is tied to PLC memory and
specifies focus type (i changed it from flashing inverted to just inverted).
the frame around it is touch switch object which brings popup window
(Input Key window/keyboard specify keyboard screen number).
notes:
you can have different functions assigned to touch switch.
pay attention to cursor location or you may end up overwriting wrong value.
objects on screens interact with tables (numeric string etc.).
tables contain reference to PLC memory locations.
