Assuming that you already have 0 in "P" and "C" of your PRV instruction, could you post your code?

On a given screen you select all, then edit properties. You get a table where it is easy to copy-paste text, attribute, etc... between elements.

Hi buzzmethru, you are welcome!

There is how i would do it, based from how i understud what you want to do. Some points were not clear so you will have to make some ajustments. You will notice i used counters instead of increment and compare DM's, i forgot to suggest this alternative the other day. HTRS.SWP

It seem that you not only need help with timers, but with basic logic and structure. Maybe its my poor english, but i have difficult to figure out what you want to do. Here is how i see it, (correct me if i am wrong) and questions about things seem to be missing: 1: You want to start heater1 5 minutes after input 0.01 is ON. 2: You want that timer be cumulative in case the input 0.01 goes OFF before that 5 min. 3: After that 5 min you want to energize heater 1 (output 10.01) Question: Then, if the input 0.01 goes OFF, what do you want heater 1 to do? 4: 15 minutes after that 5 min you want to energize heater 2 (output 10.02) Question: At that moment do you want heater 1 to continue? 5: 5 minutes after the OFF signal (Input 0.02) you want to shut down heater 2 Question: If input 0.01 goes ON before the 5 min, what do you want to do? Your ON and OFF signals seem unusual to me. Your drawing say you have a DTST switch ( so impossible to have input 0.01 and input 0.02 at the same time) but from your explanations i understand that you could have both signals at the same time. Am i correct?

I still dont understand very well but here is how i suggest to replace your timer with 1 sec clock pulses.

Not sure that i understand well your points 4 and 5, but if so, i would advice you to, instead of timers, use 1 sec pulses (255.02) to increase or decrease a DM (INC or DEC instruction) then compare the value of that DM to the number you want.

Hi Ben, I tested with a G9SA. The current for a safety input, when the relay is energised, is 24 mA. So the drop with a 46 ohm resistance would be 1.1V. There is no problem at 1.1V, i tested with a potentiometer and about 4-5V drop before it trip. If you want a relay with less input consuption, i think you could try a G9SX. He is solid-state.

Voltage drop depend on the resistance of your wire X the current drawn by each input channel of your safety relay . Each of your loop would have 2.2km of wire. 18AWG wire has a resistance of about 21 ohm/km, so you have about 46ohm for a loop. G9SP has 6 mA consuption for each input. So the Voltage drop would be 46 x .006 = 0.28V (for 18AWG). 14 AWG has a resistance of less than 9 ohm/km. So it would give a drop of 0.12 V for 2.2 km. I have G9SA and G9SP at my job that i could test monday (measure "real life" input current). The number i used (6mA) were from Omron spec. for G9SP , i did not find it for G9SA.

In "System tab, Project Property": Switch Label tab, No. of label: the number you need. Then you specify a name for each ( english, portuguese...) and wich of them is the initial label. Then when you create an object than contain text (button, messages, etc.) you always have a Label or text tab in wich you fill the text for your 2 languages. Finaly you need a "word button" to write the label number you want to display. With this word button you write to a System ($SW) adress. (Initial allocation that you specified in "System Setting + 10 )

He meant Structured Text... First of all what is your PLC? As lostcontrol suggested can you post your ladder?

I think he had in mind to replace NT20 with NT21. Same panel cutout, easy program conversion. (Resolution not exactly the same)

Maybe there is a better way than this, but i remember that, in the memory window in CXP, we can highlight an area, and copy/paste between that cxp table to/from an Excel table. You could open 2 instances of CXP and copy/paste directly from area of memory window of the 2 projects.

DId you try both ports, mini-peripheral and the DB9?

Can you connect with CX-Programmer or Syswin? If yes you can see the error log there. It would help you, or help people here to help you.

I thought that 30, 40 and 60 I/O CP1L allowed 3 expansion units even if they need 4 words each, as for the TS002. I never found any mention of limitation in term of number of total words for theses expansions. If it is the case it allow 12 thermocouples input. If not i would appreciate if someone would indicate me where i can find it in documentations. CP1H allow 7 expansion or a maximum of 15 words, wich mean that it allow 14 thermocouples inputs. (3x TS002 (12 words)+ 1x TS001 (2 words))

I dont remember if it is Integer or BCD, but there is no need for scaling. If you want it Float you will have to convert it.

Sorry, just wanted to suggest what seemed a better solution. That is one of the goals of this kind of forum. Your CP1L is great for that...just add 2 temperature sensor unit (CP1W-TS002). They have 4 thermocouple input each.

Maybe it is cheaper to buy 10 controlers than add expansions to a PLC to control 10 zones. What is this PLC?

You need a temperature controler (not a PLC). It read the temperature, dislay it, and control your heating device (SSR...) There is an example: https://www.omron247.com/Industrial-Automation/Store/OmronProductDetailView?productId=61447&langId=-1&storeId=10051&catalogId=10051&parent_category_rn=12312
