Pinstamp
By neilr216
TASK:
Do more with less.
Write PLC code for an ancient Telesis pinstamp printer
from the early 1990's, replacing a flaky ink jet printer
that never worked properly
Existing control system is an AB SLC500 PLC controlling
a sixteen station assembly line.
An AB basic module was used to communicate to the ink jet.
Our options were:
1) Modify basic module code to suit ancient pinstamp
2) Find another way of doing it since we were in a hurry
and didn't have enough experience with the AB system
to do it in time.
We opted to take an existing OMRON CQM1 PLC that we had
gathering dust in the corner, and write code for the pinstamp
Our part model and reject codes would be sent from the AB
discretely as binary inputs to the CQM1
Using the CQM1 RS-232 port, the Telesis functions strictly
as a printer with no confirmation signals sent back to the CQM1
Having installed a clock module in the CQM1 we were able to extract
the Julian day and year and print it along with the model # and
reject code .
Not exactly the finest example of modern technology, but it
works.
Who said that OMRON and AB can't get along!
P.S. - DM memory saved in project!

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.

NJ/NX Get IP Address
By photovoltaic
A Library containing a function Block that can be run on any Omron NJ or NX PLC. The Function Block will retrieve the host PLC's IP address, Subnet Mask, Gateway, and MAC Address. The Port Details are displayed through 2 structures , 1 per-port. In the event you only have 1 Ethernet port then the structure for the 2nd port will contain all 0s. Data Format:
IP Address - USINT[4]
Subnet - USINT[4]
Gateway - USINT[4]
MAC - BYTE[6] (hex value)
Access the retrieved details by the typical parent-child tag structure. ex. Port_1_Detals.IP_Address[0] will get the first octet of Port 1's IP.
Tested on: NX1P2, NX102, NX502, NX7, and NJ301
IMPORTANT: This Function Block should not be run immediately after startup. Allow the PLC a few seconds to establish a connection with the Ethernet network.

Sysmac Studio Simple PID Example
By photovoltaic
A simple test program and starting values for the PIDAT instruction in Sysmac Studio. Simply run the simulator (Simulation-> Run) and toggle the Test_PID bit. Simulated feedback will allow the loop to operate normally. The setpoint can be adjusted by modifying the PID_SP variable. There is a pre-programmed data trace that traces the SP, MV, and PV.
To use the data trace navigate to DataTrace0 and start the trace, flip the Test_PID bit true and the trace will log 10k samples. Change the SP and view the behavior when the trace finishes.

MY PIDAT CONTROLLER SIMULATOR IN CX PROGRAMMER
By suresh_
this is my PIDAT simulator for CX programmer. D100 is the Steady State (50BCD in the example), D410 is (simulated) Process value. It needs a Omron PLC ( kind of CP1E) with n.01 AI, n.01 AO ( AO needs to be wired to AI to run the simulator). When starting set D410 (0:100) and start PIDAT to see the regulator at work. Keep AT OFF to see tracking process.
