Sleepy wombat: Maybee ill get back to you if i cant get it to work sorry about asking so much

no no was only if anyone had some examples of PID use of setpoint entering etc etc im not asking for a complete program im aware of that this program takes time but maybe there was some one out there that had made some steering for heating or cooling or something else then i could look at theese examples and maybee get som good ideas hope maybe you guys had some examples or knew of some places or books were there was some good illustrations of heating systems or just some good examples of tranfering data fra plc to pt i have used the examples in the guide i found on the hmi example side. And i have learned a lot soon ill post some of the first programming i made so far

why ar you shaking your head

jay thanks very much cant wait to get some programmed have a little question ill make some thing that control the burning process in my pellets burner and i was thinking something like this Have a Setpoint for the HEAT ex. 60 setpoint for the oxygen level ex 13% setpoint for the pulse of my feading system ex 0-4 sec setpoint for time between the pulse for feading pellets 0-4 sec setpoint for snailmax "feading system" 0-100% setpoint for Blower 0-100% setpoint for ignite the pellets 0-100% setpoint for time for the ignition of pellets 0-180sec Reading af temperature in pelletburner 0-200grades "pt100" The exhaust pipe 0-450grades "pt1000" The exhaust pipe in the top of exhaust pipe 0-200grades "pt100" The oxygen level 0-100% thru a Lamda sonde with these things i would like to make the controller modulating the input of pellets and oxygen for making the best burning process i would like the controller to regulate the use of pellets by calculating the oxygen and the heat in the burner. If the heat isnt rising the it should automaticaly feat more pellets. Then it should read the o2 if this is to weak it shall blow more when a good o2 is ok. it shall look at the temp in burner is it rising it shall stay there until getting near of burner setpoint. when getting closer the controller shall give less pellets and less blow by the end reach the setpoint of the blower Any one knowing some smart ways of programming this i think ill use the temp controller cardd i have with 2 loops for the burner process and the oxygen process theese should be use together with a PID regulator The other input is put in the plc thru the AD041 cards The output for the blower and snail are controlled by 2 frekvenscontrolere and gets there setpoints from a DA02 ill use MOV(21) for moving data into data words these ill compare with the setpoints and make the burning process work anyone have time to help making some small aplication, hints or small bites of program examples please post them they are more than welcome ill be posting the things ill be making

Found this and i have located the analog in and out so please help with the other AD041 card and im on my way!!!! IR237 Analog output 2 IR236 Analog output 1 IR235 Analog input 4 IR234 Analog input 3 IR233 Analog input 2 IR232 Analog input 1

cpu45, OCH, ID212, ID211, OC212, OC212, IS01, DA021 am i right when i say this OCH 000.00-000.15 ID212 001.00-001.15 ID211 002.00-002.15 OC212 100.00-100.15 OC212 200.00-200.15 or is it some other adress DA021 ?? what adress do this get i have read some place 191, 192, 193, 194 and if i connect the following next to the DA021 AD041 What adress are theese getting AD041 What adress are theese getting IS02 And maybee one more DA021 What adress are theese getting IS01 I have seen on some papers that the cqm1 cpu45 should have 4 analog in where and how do i use them ? thru one of the ports in the front or thru the indput card hope you guys can help

thanks guys i think i got closer to the finish line now this is a super forum. i have learned a lot here ill try start making my program and then ill post some in here mabye you guys have some changes thats make it very good keep up the good work guys

yes i think so have the following setup cpu45, OCH, ID212, ID211, OC212, OC212, IS01, DA021 what should i then call them can i call them 013 and 015...........099 how many can i use hope you can help have seen you have the answer for almost everything please dont write look at manual im better with learning by doing

have a problem when i use the MOVE(21) then i move data from a thumbwheel to a data string move(21) 003 to 005 but it wont work im using a 10.00 contact activated from the screen to set the move function for calling the screen im using Mov(21) #0001 to Hr00080 this is activated with and activation bit thats comes when start up plc under PT config im using H80 and H90 the last window area what is this for do i have to have any H?? there

are there any premade program for this aplication mabye for cqm1 cpu45 http://forums.mrplc.com/index.php?autocom=downloads&showfile=102

im also in the learning stage have you found some sites on the net or some traning course im programming a cqm1 cpu45 and a NT31c touch screen i also have cpm2a and a cqm1 cpu 21 mabye we could exchange ideas and programs

Thanks a lot for all the information ill start making some simple programs at once i have made a lot of programs for the omron plc in my early years but when you dont work with it every day you forget a lot of things but ill look in the manual for finding out the mystery of controling the plc with the pt

that would be nice have send you a pm i have a problem i can get online with the plc thru the Cif cable and i can also get online with the peripheral port and the pc i can download screens into the NT31C from plc i can connect the screen to the plc and get connection but i cant program the plc with the peripheral port when i have the NT31C connected to the plc on the rs 232 port i think its some parameters i have to set But were are they it have something to do with dip switch 5 because when switch on and of i have a different senario should you not be able to program the NT31C through the plcs peripheral port when the NT31C is connected to the plc via rs 232 and plc via the peripheral port hope some have a little more help because im a little stuck at the momment but i have already discorvered a lot and im going in the right direction i also have a litle problem with PT setup on NT31C the things about holding relay bits etc etc. Anyone who can explain this in a simple way. thank to all have a nice weekend

I have some examples of the CQM1 setup with the TC modules, but not the analogue with the separate power supply, as well as NT31C. I dont have enough time just now to post some basic examples, I may get a chance over the weekend. With manuals, you have to read, absorb, read, absorb some more, read, absorb, read, absorb some more, read, absorb, read, absorb some more...... then try some for yourself, well thats what I find anyway. If you persevere, I am sure you will get there in the end.

yes ill look in them i got the solution on the last problem here on this site it was more if anyone had some program examples i could look at so i didnt have to discover the deap dinner plate again you can read and read some time you cant get any were but then you see a example and all things seems more clear to you but still if anyone should have anything a old book from schooltime or some program examples come with them are there any cqm1 plcs for dummies making some examples from start to end combined with NT31C
