i suggest that you have a long hard look at the Host Link (sysmac way) communications manual. have a look at the sample VB code in the down load section Have a read of the CPM2A operation manual to understand what a PLC is and memory structure then come back and ask again..

Might sound a bit silly... but look at a PLC vendor site.... for example - https://www.omron.com.au/ under service and support... just an idea...

from memory the system variables like 1 sec timer bitts will convert automatically... ie old 1 sec timer bt 255.02 will convert automatically to CF102. however there is a address allocation for outputs mainly that does not convert automatically... ie CPM2A will start output addressing at 10.00, 10.01 etc.... the CP1L will start output addressing from 100.00, 100.01... there is a quick replace tool that can update the addresses in a couple of clicks..

Hi Jaakko, Thanks for the info on the FFT. Most people on the forum would not have been taught FFT in their education, and I have never thought of the use of them beyond frequency isolation in communication systems with FSK, AFSK in mind for data protection on radio comm's/ mobile phones etc. Not sure of what you are trying to achieve with the of the application of a FFT on a Low Pass Filter for analogue signal... Are you trying to eliminate noise ?

Found a tech note on omron EU site...and have instructed the client IT with it.... have not heard anything back as yet from them... CX-Supervisor(and CX-Server) require Administrator rights to be installed on a computer, but other users can then run the software. The run time will run without problems as a Standard User (member of Power Users group) and will run as a Restricted User (member of Users Group) although will show errors when trying to update the registry. To avoid these errors specific registry access can be provided by an Administrator to the following registry keys: •HKEY_CLASSES_ROOT\CLSID\{0002D780-0000-0000-C000-000000000046} •HKEY_CLASSES_ROOT\CLSID\{0002D781-0000-0000-C000-000000000046} •HKEY_CLASSES_ROOT\CX-Supervisor.Application •HKEY_CLASSES_ROOT\CX-Supervisor.Project

You would generally use the "out" coil instead of the SETB. The SETB was developed mainly to address setting a bit of a DM address although it can be used for other memory areas. SET w100.0 is usually paired with a RSET instruction, but allows the flexibility to have the RSET in a different rung.The KEEP will form the same effect as above but is only in one rung.Also you could create self hold logic which is equivalent as well. You get a warning because the address w100.0 is listed more then once in the program, ie if you used the Out coil w100.0 down further in the program the software is simply warning you that the last one will have the overriding state.

Memory Used in a PLC... In CX-Programmer go to the "View" tab then -> "Memory View" this will display Total memory, Free memory and used memory. The memory figures are expressed in Steps. A simple LD instruction would take 1 step. where as a MOV instruction would be 3 steps. Regards to estimating the programme size you can look at the instruction reference manual and there is a section on the instructions and the number of steps they use... Regards selecting the PLC.. how many digital IO are you using ? how many analogues ? is there screen interfacing ? is there a lot of calculations ? will there be a lot of FB's?

Wow, another thread resurrected from the dead, seven years later... thats got to be a record.... BTW Tim, did you find your answer on Google ? if not remember to try Yahoo... while your at it try Alta Vista and Bing and ........

I have to laugh when 2 year old threads get dug up... all i can picture is the poor sod still trying to sort the problem out rocking in the corner.. and then alas the thread is resurrected again and he has a glimmer of hope of completing his project...

What PLC model. if CP1/CJ1/CS1 then simply use *(420) #E32C &2 D0 # indicates hex number & is integer D0 is memory location to store result

Hey, Bobb what tI belive the guy was doing was simply embedding a web browser into a citect project so that he could view the inbuilt web data from the device in the field. He wasn't running citect remotely via a web browser shell. for your application though there are a few options for remote control...

Yep you can use that version... both versions were called NT-Series Support Tool.... (except the windows one had the statement "NT-Series Support Tool for Windows Ver 4.7") I do not recall if you could use this version with win 3.1 (i know the dos one could certainly work under win 3.1 in a dos shell) I thought that this windows version was compatible with Windows 95, Windows 98 and Windows NT Please find attached manual below for the Windows version NT Series Support Tool for Windows V.47 Manual Regards

PMCR - great response.

I haven't programmed one of those screen in 17 years... The software is DOS based. You will have to put the screen into a transmit mode before being able to "RECEIVE" the screen data to the PC. I have attached the manuals below for the NT 620C and the NT support software... I suggest that you have a read of them to familiarise yourself with them.

Bob should not remove the "Flag" and this post will continue to be monitored closely. Bob's request was quite reasonable that both dmargineau and Gerry "can" the personal banter and attacks. You both have different approaches to solving the problem at hand. From what I have understood, both of you have a good knowledge base. We thank you for your numerous reponses on the fourm however If you both cannot play nice then the mod team will consider other action. This forum is not a tool to be used as a "pissing contest". Please keep responses on topic and not personal.

Like every other question you seem to be posing on this forum lately, they appear straight out of a text book / class teacher notebook.... You are in Oz, are you going to TAFE or UNI... if so .... don;t you think that the learning process would require more effort on your part other than posting a question and simply assuming that forum participants would simply pass on their hard earned knowledge. We all volunteer our help here, and will generally help where we can, espeically if the person has shown some effort in trying to understand the problem and made a genuine effort... you have more tools available to you to learn about everything then most of us ever did......if you don;t put in the effort then you will start getting the response with another acronym that you can look up.. RTFM...

your wiring for a loop powered transmitter is correct ! but you will need to refer to the manual when programming as there are some settings etc for the analogue card to function correctly.

never really came across a RS485 4 wire... has to do with the line driver arrangement of the electronics for the comm's... gernerally RS485 is also HALF Duplex communications where 422 is FULL DUPLEX comm's. I have paired on an Omron serial RS422 device to RS485, but that only worked because it was designed to be wired that way to convert... i do not recommend it. depending on the distance also you might have to match impedance at both ends (usually a dip switch of software switch...or worse case install a 110ohm resistor at both ends I would persue and recommend the isolator/convertor option...
