Lowpass filter function block
By pat.stave
Lowpass filter for Omron PLCs.
Only tested on CJ-series CPU. Use at own risk!
Many thanks to Peter Nachtwey @ PLCS.net for providing the mathematical formula.
Unfiltered = raw unfiltered value in INT.
TC = Time constant tau, given in seconds.
Filtered = Filtered value in INT.
FilteredReal = Filtered value in REAL.
- The FB can be duplicated.
- The FB can only be used in program parts that are scanned every CPU cycle, as it relies on the "P_Scan_Time_Value" variable.
According to the working principles of a lowpass filter, it will take the filtered value tau amount of seconds to reach 63% of the unfiltered value.
The value will reach within 1% of the unfiltered value in approx 5x tau.

FINS Ethernet Master / Slave Solution
By PMCR
Drop in code for Single Master and up to 30 Slave PLCs on FINS Ethernet.
The Master PLC can be a CP1L-E, CJ2M, CJ2H, CS1, or any PLC capable of sending FINS commands.
Originally designed to share data across a network of CP1L-E PLCs.
Each PLC shares 100 words in each direction with the master PLC.
The reads can be setup to read as fast as possible, or at a given interval.
The writes can be change of state (COS) driven, as fast as possible, or at a given interval.
.pdf manual included.

FB : Password Set
By ne0tec
There was already a nice FB made available by PMCR, but it had little restriction which I didn't liked. So I made this one. This FunctionBlock enables you to set a password like '1234OOPS' rather instead of being limited by HEX digits (0-9..A-F)
So it's kinda a alternative to the one PMCR made available.
I also added another functionality. This Function Block is configurable to work in automatic mode (password will be set on certain PLC hour) and/or manual mode, where you can give a trigger to the Function Block which will set the password (as example, when you're finished with online editing you can trigger the FB)
I think it will explain itself. If you have questions, you can PM me.
Have phun!

Easy to use Modbus RTU Master for CP1L CP1H CJ1 CJ2 CS1
By PMCR
This application is a ready to use Modbus RTU master for CP1L, CP1H, CJ1, CJ2, and CS1.
The user creates 'tables' of items to read and write. The ladder code automatically performs the communications as setup by the user.
The CJ1 / CJ2 / CS1 solution requires the use of a Protocol Macro on an SCU31 / SCU41 module, and the CP1L / CP1H function uses the Serial Gateway function of the CP1H / CP1L on a CP1W-CIF11 or CIF12.
Sample NS screens are provided with an Omron 3G3JX inverter as an example Modbus RTU slave.
Updated 1/7/2011 to include 3G3MX2 screen for NS, and to include CJ1W-SCU22,32,42 in documentation.
Updated 9/19/2012 to support 2 ports on an SCU card (CS, CJ1, CJ2) or 2 ports on a CP1L / CP1H.
